"The surge in math deficiencies after dropping the SAT highlights a systemic issue: grade inflation. Without a standardized baseline like the SAT/ACT, a 4.0 GPA from a high school with relaxed standards looks identical to a 4.0 from a highly rigorous one.

Paradoxically, removing test requirements harms underprivileged students the most. Preparing for the SAT requires a book and an internet connection. In contrast, building a competitive profile based entirely on expensive extracurriculars, sports, and elite summer camps is far more wealth-dependent. Standardized testing isn't perfect, but it's often the only objective equalizer we have."

ceejayoz•47m ago
> Preparing for the SAT requires a book and an internet connection.

Sports frequently just requires a ball or a place to run.

In both scenarios, you can still purchase better equipment/training. There are very expensive, effective SAT prep options out there for the wealthy.

Your analogy works against you, given that tons of professional athletes come from poverty.
ceejayoz•42m ago
Professional athletes are like people who get 1600s on the SAT; a bit of an outlier.
Aarostotle•33m ago
That's exactly the point. Top schools are looking for outlier intellectual talent, but the egalitarian approach (high school grade inflation plus weakening of standardized testing) smooths the differences and makes it harder for them to admit the right people.

The visible result has been the weakening of these institutions. Do also observe that this is recursive — as these institutions have lowered their standards over decades, the people who go through them and end up leading them are weaker, too.

ceejayoz•29m ago

My kids were able to take some SAT test prep course through their school (partially funded by the PTA) and it helped a lot. They wrote a bunch of practice exams and each time their scores went up. Also, test taking itself is a skill and the more you practice it the better you get at it. If you’ve written the SAT 15 times over the past 2 years, then the 16th time won’t be as stressful and you will know strategies that work and the questions will be familiar.

If you are in a school that doesn’t have a well funded PTA, you are at a disadvantage.

When I was in high school in California more than 20 years ago, SAT math alone was insufficient for admissions to STEM programs at mid-ranked and top-ranked universities. I was required to take the SAT Math IIC subject test, which went up to pre-calculus. We were also strongly encouraged to take calculus in high school. There are two AP Calculus exams: AB (which covers the first semester of university calculus) and BC (which covers the first two semesters).
lokar•38m ago
The problem is as never the tests. It was pretending that the difference between a 600 and 625 (or whatever) really predicted anything.

It was the silly idea that with tests you could produce a fair ordering of students based on potential to succeed.

jpadkins•31m ago
who uses SAT scores as "potential succeed"??
lokar•15m ago
The original argument for standardized tests was to pick based on how well you would do in university (vs who your parents know).
raincole•30m ago
Any working system has to rely on some arbitrary rules. Drawing a line between students who scored 600 and 625 is still infinitely better than drawing it based on the decision-makers' moods.
lokar•16m ago
Or, treat 600-625 as a tie, and use a lottery.

I wasn't underprivileged but I did go to a terrible evangelical high school that had no honors or AP classes (AP bio at a place teaching creationism would've been something else...) and I think I only got in to a decent college on the strength of my SAT and ACT scores. My grades were OK (except in bio, where I refused to acknowledge young Earth creationism) but not amazing.

i dont understand why the teachers would go out of their way to reteach middle-school math.

i teach. my courses have prerequisites. if a student somehow makes it into my class without a passing-grade grasp of the prerequisites, i will point them in the right direction to get caught up, but i am not spending any class time on it. its not fair to the other students.

It's kind of like how if you owe the bank $1000, you have a problem, but if you owe a bank $100M, they have a problem. You just can't reasonably ignore a huge portion of the class as a professor without a serious amount of documentation, and proof that you've tried to escalate and solve the issue. Ultimately, people are paying for these courses, and it's probably better to teach something rather than nothing.

>Critics call the SAT inequitable and say high school grades are a good predictor of college success.

I mean, it seems pretty clear from the last 6 years of experience by professors and others that grades (or at least grades in isolation) aren't a good predictor at all for this. The problem is removing the use of standardized tests here was done for ideological reasons. You can already tell by the use of the word "inequitable" here, because a certain insane subset of policymakers and the public believe that we should push for equal outcomes ("equity") over equal opportunity (usually referred to as simply "equality").

ceejayoz•45m ago
> the public believe that we should push for equal outcomes ("equity") over equal opportunity (usually referred to as simply "equality")

This is the direct inverse of what's actually asserted by people talking about equity.

https://en.wikipedia.org/wiki/Educational_equity

Providing a hearing aid to someone hard of hearing so they can learn is equity. Their outcomes aren't guaranteed; an obstacle to achieving them is removed.

As a product of the STEM post-SAT UC system (UCLA ‘26), I never personally experienced “middle school math” being taught or a lack of mathematical understanding.

I’ve had my fair share of classes which throw you into the deep end and not many which coddle you. Never seen any professor teaching middle school mathematics. A lot of professors started off with a vague idea of prerequisites, covered the basic ideas and usually go straight into the deep end with new material. It is up to the student to make sure they are acquainted with the prerequisites, go to discussions or office hours to ask TAs or the professor, or just drop the class and do it next quarter (without penalty). At least in my four years at UCLA, we have ample opportunity to do it and the TAs are 90% empathetic towards “stupid questions.”

So in my personal opinion, I think profs shouldn’t be wasting time teaching basic math and there are more than enough opportunities for the student to learn it at their time in the UC.

Anecdotal data point: My son is finishing 9th grade, and he's taking 10th grade math because he got ahead a year when he was younger. At his school, you're exempted from having to take the final exam if you're passing with a reasonable grade at the end of the semester. He said there are about four students who don't have to take the final exam.

Math has always been hard to teach well, because issues with earlier math classes compound so much. With all the societal interruptions to education, and the impact of addictive tech on young people's minds, it's only gotten more difficult.

kleiba2•41m ago
I used to teach high school math. There was a big push for doing everything digitally. And admittedly, for some topics the use of technology in the classroom or at home can really be a benefit, for instance visualizations or interactive exercises. But having a digital device in class was the number one cause of distraction every time.

For a lot of things, good old blackboards are just fine as are pen + paper exercises. Maybe even for most high school math. That was frowned upon though by the higher ranks. If I was evaluated as a teacher and didn't include some iPad shenanigans in the class that I was getting audited for, I would have been in trouble. How behind the times!

I got along really well with most of my teenage students, it was a lot of fun interacting with them. But the politics behind it all got too annoying. Also, you're under very tight control on what you teach and how, that was super annoying. So I stopped teaching a few years ago and never looked back.

My nephews came to the US in their early teens as non English speakers. They struggled in some of the courses but still got good grades reported to their parents. So, apparently some teachers will put them on a bus together with other minorities and take them on a day trip to the museum instead of math class, but they would still get graded. They retuned back to Spain and had a very difficult time graduating from high school because of math. So I’m not sure how well of a predictor high school is.
godsinhisheaven•38m ago
Out of the current population of college students today, what percentage shouldn't really be there, be it for lack of intelligence or too much? (e.g. smart ceo guy dropping out.) 10%? 20%? 50%? If you can't do high school level math, much less middle school, do you deserve to be in college? It really strikes at what the purpose of college is: is it for educating people, no matter their prior abilities? Or is it to foster our best and brightest to put them on a path towards advancing society? Or is it to create well-rounded individuals, knowledgeable in many different domains? I admit, perhaps the purpose is all of the above, but if so, things that try to be everything for everyone often have to make sacrifices in one area to improve another.
BigTTYGothGF•38m ago
> "We now observe preparation gaps so severe that instructors must reteach middle-school mathematics while simultaneously teaching the material students need for sciences, engineering, economics, and other quantitatively demanding fields,” they warned.

When I was a grad student in a mediocre university in a different state thirty years ago we had a lot of kids in a similar situation. This was resolved by means of a pre-placement exam, and the ones who scored the worst had to take one of two remedial math classes, the lower of which was solidly at the middle school level. The university had a SAT requirement at the time.

The pre-placement exam had two versions that were used on alternate days, and a student could take it as often as they liked.

This may be a new experience for those particular UC faculty, but it is not a new phenomenon.

jdw64•34m ago
Looking at the world, it seems we all go through similar systemic issues. Naturally, in East Asian cultures where the fervor for education is overheated, this phenomenon tended to manifest much earlier.

When specific exams are abolished or watered down under the banner of 'diversity and equal opportunity,' the wealthy actually gain a massive advantage. Of course, the exam system itself inherently favors the rich as well.

The reason is simple: weakening exams naturally forces the strengthening of alternative metrics. During the transition period when a new system is introduced to society, wealthy parents are far better equipped to adapt than poorer ones.

Korea’s 'Spoon Class Theory' (where rich parents are gold spoons and poor parents are dirt spoons) and Japan’s 'Parent Gacha' (parent lottery) stem from this exact dynamic.

Sure, standardized testing benefits the wealthy because they can hire top-tier tutors. However, when the rules of the system change entirely, the underprivileged simply do not have the buffer or resources to keep up with the shift.

collabs•34m ago
something that came to my mind as I was reading the comments here -- the thing is that in the quest for professionalism, we have sidelined a lot of people who would be good at teaching in favor of people who are good at jumping hoops. there is a famous quote saying "when the measure becomes a target, it stops being a good measure"
ryukoposting•3m ago
Goodhart's Law (that quote) is actually one of the motivations for moving away from ACT and SAT as college entry benchmarks. "Teaching to the test" is a rampant problem in the US.

UC is seeing flaws in departing from those benchmarks, though. The thing is, % of students getting admitted to college is itself a measure for schools and school districts. If GPA is how you get kids into college, well...

To me, it seems that Goodhart's Law is an inherent problem for education in the information era, no matter how you cut it. If there's one good thing that can be said about ACT and SAT, they're relatively difficult for schools to game. GPA inflation is trivial.

hedora•32m ago
This doesn't surprise me at all. From what I can tell, California's education system has moved from "equality" (which I would define as providing similar opportunities to all the kids) to focusing on "equity" (which I think they define as dictating the same outcome for all kids).

To get an idea of how off the rails this has gotten, go read up on their statements trying to justify banning high school calculus. They explicitly (in the abstract / introduction of their plan) reject the idea that some kids are more talented at some things than other kids, so if you can compute a derivative by 12th grade, it's due to racial discrimination benefiting you or something. On a related note, instead of writing some Rust code, today, I think I'll go paint a Banksy or something after I finish my coffee.

That plan caused a lot of uproar and was blocked before being implemented.

Anecdotally, when I asked our local public school for a copy of the curriculum, the teacher said they just teach common core. If you go to the common core website, somewhere towards the top it makes it clear that it is not a curriculum, and just meant to be a lower bar that gets supplemented.

Personally, I think all funding in California education (other than terminal levels like 4 year bachelors and up) should be a function of the percentage of students that succeed at the next step.

If a local district starts losing funding, then it would have to close / shrink schools, and people from outside the educational system would be allowed to establish independent (secular) charter schools within the district.

Those schools would also not be paid unless the students do well in the next phase of their education. This solves the problem of trying to use this as a curriculum back door for climate denial and Islamophobia (or whatever the red states are pushing).

ryandrake•27m ago
Measuring (and funding) schools based on student outcome is fraught because a student's performance / preparedness for the "next level" is not entirely a function of the school. There are other significant parameters, including parental upbringing, home life stability, neighborhood safety, friends, hunger/nutrition, various trauma and abuse, the list goes on. I'm sure it's been studied, but I'd bet "school quality" is not even close to number 1 on the list of predictors of educational outcome.
pgh•29m ago
The lack of any subject level standardised US high school certification to prove skill-level for matriculation still boggles my mind. I realise this is fundamentally a curriculum issue, as it’s set at a local level. There’s AP, but that’s not universally available.
WillAdams•17m ago
For my part, it has always killed me that schools don't do as one system which I once briefly attended did --- divide courses between academic and social --- academic classes are attended at one's ability level, while social classes are at one's age level.

I was in 4th grade, but attended 8th grade math, science, English, and history (there was a 4 grade cap until after 8th grade classes) while my homeroom, Phys. ed., and social studies were with my 4th grade age peers.

Some teachers at the school were also accredited as faculty at a nearby college, and for students who were able to take courses which weren't able to be taught, either a professor from the college would come to the school to be taught, or arrangements would be made to bus students to the college.

It wasn't uncommon for students to be awarded a college diploma along with their high school diploma at graduation and there were multiple instances of multiple majors being completed.

A mixture.

1) They were delusional and thought SAT/ACT scores werent useful signals for selecting qualified candidates.

2) They didn't care and prioritized the ability to admit people based off race and other demographics.

And now they are resolving the dissonance between their mission and admission policy.

Johnathan Haidt detailed this dynamic a long time ago in a lecture at Duke entitled "Two incompatible sacred values in American universities." The incompatible values being "truth" and "social justice."

There is a nother factor worth mentioning in the admissions piece - the proababilistic accuracy in admissions alongside massive increases in the number of applications students send out. The first admissions criteria is basically the ability to succeed at the institution academically. It used to be typically applied to a handful, maybe 10 max, universities. Now it is not uncommon to hear from students they applied to 40 or 50. In 2017, my university got 31k applications and accepted 7.4k students. In 2025 those numbers were 68k and 8.5k - the number of acceptances were up 20%, the applications were up 115%. If you assume admissions process has a 95% accuracy, that predicts a huge increase in 'false positives' dropping from 85% of students we expect to be 'correctly' prepared to 74%.

Add to that that the quality of math learning outcomes and math learning in K-12 has gone WAY down. I point this squarely at 2 factors - No child left behind and the rejection of the common core because parents no lnoger felthtey understood the math their kids were learning. (and teachers did not understand math well enough to teach it well as a conceptual matter).

Even if they are getting the grades and even getting the test scores, they increasingly undersstand very little. They are not prepared for understnading they are prepared for question answering. Even in advnaced classes I see students actively reject learning and understanding for just answering - answering is the point they have learned. Right answers are the point, the only point.

A colleague and I were recently talking about what they see their middle nad high schoolers being taught in math classes. They termed it 'calculation as a defense against analysis'

SATs might help some but they aren't the problem they are a stop gap. K-12 (and by extension college) have so heavily sought to (poorly) quantify every aspect of experience to evalute people that they have stripped any meaning from the process. The problem is nothing has useful predictive value anymore in a process that is oversaturated by a 115% increase in the number of decisions an admissions office has to make. Its a math problem more than a cultural or standards problem.

scarmig•23m ago
You can absolutely make a bet on who's more likely to succeed based on a 100 point difference, though. It's not absolute, but it's highly predictive. And the reason the SAT was dropped wasn't because admissions were being forced to blindly accept 620 over 610 (they never were), but so that people who scored hundreds of points below the mean could be admitted (in the pursuit of other institutional goals).
lokar•16m ago
We have decades of data (test score vs grades and degree completion). They should gather it up and calculate the answers.

Flip answer: the bucket width should be 2.5 times the score improved of a prep course.

whenever i have had a larger-than-normal percent of my students failing, i am provided an opportunity to explain it.

SpicyLemonZest•45m ago
The full letter (https://ucstudentsuccess.org/) gestures towards "growing pressure to dilute quantitative rigor". The strong implication seems to be that some administrators have told some faculty that the failure rates you'd get from holding the line are unacceptable. Presumably they don't want to frame this issue as a faculty vs. administration thing, which makes sense to me.

That is the entire problem in a nutshell. You cannot reject more than one or two students in a year or the school will reject you.
scarmig•32m ago
That's a symptom of the problem, not the problem itself.

Treating universities as a system, it is deeply problematic and even immoral to saddle students with tens or hundreds of thousands of dollars of debt to enter programs that it is entirely predictable that the student will fail at.

The solution is to use all the methods available to predict how successful the student is likely to be after matriculating, not to water down curriculum to the point where the most marginal student in the class will pass.

No, moral is to make student loans subject to regular bankrupcy. Student should be also able to get refound, if university misrepresents or lies about their job prospects!

Universities are business as any other!

SoftTalker•20m ago
But universities need the tuition to support ever more bloated administrative hierarchies and salaries. Most are in a state of abject panic because international graduate enrollments (a cash cow) are way down in the past couple of years. Staff layoffs are starting to happen, which were previously almost unheard of.

>You cannot reject more than one or two students in a year

this seems absurdly low, from my experience. but i have only taught in one school, so maybe we're the outlier? i would say one to two failing students per course is the baseline, not the cap.

can you share where you are getting this number from? is that the guideline where you teach?

everdrive•25m ago
In part this is a consequence of blank slate ideology, which presupposes that all students are equally capable of identical outcomes and that individual student fails are always / usually systemic failures in disguise.

This is a silly perspective, but the blank slate folks really got their tendrils in just about anywhere. In reality, some people are simply bad at math. More education will help, but they will always be disadvantaged to people who are more naturally predisposed. (note, I'm quite bad at math myself)

It may seem altruistic to err on the side of caution here and try to catch the kids that fall through the gaps, (again, assuming that they are falling through the gaps due to systemic failures) but as the article points out, there is a limit to this approach; eventually it brings the talented students down and degrades the program.

If I may assume, I think GP is alluding to the likelihood that such students are going to be minorities from poor socioeconomic backgrounds. If they are failing in large numbers, that will open the door to claims of systemic discrimination.

Also these are most likely the first classes. You can not block most of your entering cohort. Or even any way significant part. At least in the system these professors exist in. In some other systems like say German where getting in easy and getting rid of some is normal would be different.

This shouldn't be a hard problem to solve. At the state university I'm most familiar with, every incoming Freshman takes a math assessment test. If they don't pass it, they have to take remadial coursework (which does not count towards their degree requirements).

And yes, every student takes it, even the ones with high school AP math and high SAT math scores. The only exception might be if they have already completed and passed actual accredited university math courses for credit.

Do they not have remedial classes for these students? It's been more than 20 years, but back in my day, if you weren't ready for entry level classes (but still got in to university) you took remedial classes first.

The processes for delivering remedial classes no longer work at the scale required. UC San Diego published a detailed report (https://senate.ucsd.edu/media/740347/sawg-report-on-admissio...): their remedial math placement grew from 32 students in 2020 to 921 students in 2025, and 665 of those 2025 students placed into an extra-remedial course covering grade 1-8 math which had not previously been needed.

i dont have any 1st-year courses though, which is where a lot of students are filtered out (for various reasons), so im not in the best position to answer that question.

malshe•37m ago
I agree with you and think this claim needs a lot more evidence. In my university we have been providing remedial math classes for freshman students for a long time. They must pass these before taking regular classes that have math prerequisites.

I had to take a math placement test which was exactly "do you need to take remedial math?" in test form, passing the test was a prereq for a large swath of math/science/engineering classes
fabian2k•34m ago
It's a different country and a different time, but when I studied (a natural science) there were dedicated courses at the start for refreshing high school math. Those were optional, and covered relatively simple topics.

There was also a real math lecture that went into topics above high school math, but also contained some repetition. All other courses mostly relied on what was contained there.

So I would fully agree, but I'd also be a bit surprised if you don't have any dedicated "math for scientists"-like courses to cover the stuff usually needed.

john_strinlai•32m ago
>So I would fully agree, but I'd also be a bit surprised if you don't have any dedicated "math for scientists"-like courses to cover the stuff usually needed.

we do! those are dedicated courses, where it is expected that the students are taking it to catch up (i.e. no prereq)

students can also drop a course within the first 4 weeks for no penalty, and retake it in a later semester if they figure out they they are behind and would not perform well.

delusional•28m ago
Because the like teaching and believe in giving their students/customers the best possible education?

I get not wanting to waste the time of the better students, but if too many student are behind, whose time are you really wasting?

thinkingtoilet•4m ago
But it goes both ways. If a student doesn't have the prerequisite knowledge for a class it is absolutely unfair and decidedly not the best possible education to slow the class down for students who are prepared. If a class requires X, and you don't have X, that's a you problem, not a university/teacher problem.
jancsika•11m ago
> i dont understand why the teachers would go out of their way to reteach middle-school math.

"gaps" implies a critical mass of students who require middle-school math reteaching.

> i teach.

If you've taught for a non-trivial amount of time, you did one of the following with that class:

* graded on a curve so you don't fail half the class

* failed half the class, and got suspended (pours one out for my compsci professor in college who did that!)

Which was it?

rTX5CMRXIfFG•6m ago
What isn’t fair is for schools to take students’ matriculation and set them up for years of debt, apparently without any intention of educating them properly as per your comment. Better for schools to just screen based on standardized test scores

Sure, but the reality is that such conditions do interfere with the potential of academic success, as much as proponents of equity like to argue otherwise. If I had a severe brain injury as a child, or my mom drank and did a ton of drugs while pregnant with me, or any number of other reasons, I will probably be far less academically successful than in the counterfactual reality where I didn't get a brick dropped on my head as a child.

Equality proponents argue that brick-on-head and no-brick-on-head should be judged by the same standards. Equity proponents argue that brick-on-head should be given advantages over no-brick-on-head to make them obtain substantially similar educational outcomes.

Once again, from your own link:

>Equity recognizes this uneven playing field and aims to take extra measures by giving those in need more than those who are not. Equity aims to achieve equal outcomes for groups, also called substantive equality. Equity aims to ensure that everyone's lifestyle is equal, even if that requires unequal distribution of access and goods.

ceejayoz•31m ago
In your scenarios, equity proponents would tend to advocate for things like extra testing time, access to tutoring, etc.

(And systemic efforts to prevent dropping bricks on childrens' heads in the first place.)

JCTheDenthog•23m ago
>In your scenarios, equity proponents would tend to advocate for things like extra testing time, access to tutoring, etc.

So you claim, but in reality proponents of equity instituted a system that gave Black students a roughly 450 point advantage over Asian students on the SAT:

https://www.nytimes.com/2017/01/30/opinion/white-students-un...

Note that the NYT, in their pure, non-partisan spirit of fairness and equity, somehow found a way to describe this as an unfair advantage for White students.

ceejayoz•19m ago
> somehow found a way to describe this as an unfair advantage for White students

Make up your mind? If their having to score higher than Black students is unfair, how is "Asian-Americans had to score 140 points higher on their SATs than whites" not also unfair?

What if raw SAT score doesn't perfectly reflect lifelong achievement? As I noted elsewhere in the thread, wealth (translated to parenting time, tutoring access, better schools, etc.) can help do better on the SAT. How does one account for that?

JCTheDenthog•4m ago
I didn't say it was fair, I was pointing out the NYT being racially biased (as per usual). Imagine at a school that Jenny gets 10 cookies from the teacher, Timmy gets 3, and Johnny gets two. Billy sees all this, but he has a crush on Jenny, so when he tells everyone on the playground about it he doesn't say "Jenny got way more cookies than Johnny, that's so unfair!" Instead he says "Timmy got more cookies than Johnny, that's so unfair!". That's the ridiculousness that I'm pointing out here.

>What if raw SAT score doesn't perfectly reflect lifelong achievement?

It was never intended to?

>How does one account for that?

It's impossible to account for everything. As much as the thinkers of the Enlightenment and their successors have attempted to quantify and measure everything, it's simply not possible in reality. If someone could devise a better means of measurement than current standardized tests like the SAT and ACT, I would happily welcome them.

But one thing is pretty clear and certain: the SAT is a far better measure of mathematical aptitude that high school grades, and until better measures can be found and implemented I fully support continuing to use it for college admissions and college math placement.

TimorousBestie•19m ago
> Sure, but the reality is that such conditions do interfere with the potential of academic success, as much as proponents of equity like to argue otherwise.

This is a bizarre claim in the second clause. Proponents of equity do recognize that various conditions impact academic potential; otherwise, they wouldn’t attempt to ameliorate them.

You even quoted, “Equity recognizes this uneven playing field. . .” so where did “. . . as much as proponents of equity like to argue otherwise,” even come from?

JCTheDenthog•12m ago
The person I was replying to quoted the article saying "conditions should not interfere", my point was that they do interfere, and will continue to interfere, in spite of all the efforts and hands on the scale and discrimination that equity proponents try to implement. Equity fundamentally arises from a more or less "blank-slatist" view of humans, which is why it leads to such insane outcomes when it comes into contact with reality.
JCTheDenthog•43m ago
>This is the direct inverse of what's actually asserted by people talking about equity.

From the wiki article you linked:

>Equity is equality of outcome for all subgroups in society. Equity proponents believe that some are at a larger disadvantage than others and aims to compensate for this to ensure that everyone can attain the same lifestyle.

If you hold a race, but some people start further behind others, they have a longer track to run. I think we can agree that to call it a fair race, we'd want to accommodate for the track length.
JCTheDenthog•30m ago
Sure, but if some people are faster than others because they have longer legs or because they've trained more etc. then people without such advantages aren't given special accomodation. It actually runs in my family that we have very short legs in comparison to our torsos. For example I'm 6' tall but look like I'm 6' 4" or thereabouts when sitting down next to someone with more normal proportions. In spite of this disadvantage, one of my brothers did cross country in high school and still runs half-marathons every year or so. He doesn't demand to be given a head start or to have time subtracted to accommodate his inherent disadvantage, because that's the difference between equality and equity.
9dev•6m ago
And that's commendable, but what if your brother would not have had time for doing cross country in high school because he had to care for his siblings as your parents were poor and working double shifts? Or so heavily indebted due to a cancer therapy that he couldn't afford running shoes?

> people without such advantages aren't given special accomodation

They are not - but I'm specifically talking about the reverse case, where people start with extra disadvantages that cause them to start even further behind their peers. Curiously, everyone seems to understand the purpose of handicaps in Golf, but it's an outrageously leftist concept in social contexts.

elteto•3m ago
That all sounds great in theory but in practice it devolves not into only giving extra help to those in need, but also to _take away_ from those perceived to have some sort of advantage. See for example NYC's idiotic plan to close gifted and talended kindergarten programs in public schools.

The truth is that it is a hell of a lot easier to lower the bar for everyone than to raise it. I.e. it's a lot easier to make dumb kids than to make smart ones, so in the name of equity we shall have dumber ones.

Yes it is cheaper and who will steal or rob a student of pencil and paper compared to a iPad also pencil and paper doesn’t require age verification.

It's also probably good to make sure students know how to figure using a pencil and paper because pulling a calculator out on a job site is pretty impractical.

It’s definitely actively bad to involve a device in the vast majority of education. And, it’s a purely selfish thing by tech companies to insert themselves into education.

A student should not see a computer until college or vocational school unless they are taking e.g a high school programming or electronics class.

They got rid of paper because teachers are lazy and do not want to spend time grading things by hand.

I’ve spoken to the head of curriculum at a school asking why when given the choice of paper or digital format of a math exam, they picked the digital. I specifically mentioned it’d be inferior as students would not be able to draw atop geometry problems or cross out numbers when simplifying expressions.

The response I got was, “we encourage students to redraw the entire picture on paper as rewriting the entire question is helpful”.

It’s strictly worse. They know it is. And they do not care.

I suggest you glance at the novel Ananthem by Neal Stephenson. The core plot device is about "universities" stripping all worldly items away from the students, so they are left with simple clothes and chalkboards. Fascinating topic, well executed by Neal. One of my favorite books.
hedora•9m ago
This is true. There are safeguards (that are currently failing) that my program would engage:

- The state is legally required to provide those kids with an education.

- There is funding allocated to help those districts.

If "we will not pay you if the kids do not learn" means there are zero schools in those districts then (1) the state government will get sued for not doing its job (because closing 100% of the schools makes the failure objective and obvious) and (2) it will have to update those funding formulas so that it is possible for some school (state run, or private) to break even while providing an education in those areas.

> I think all funding in California education (other than terminal levels like 4 year bachelors and up) should be a function of the percentage of students that succeed at the next step.

This seems problematic.

Areas already doing well likely don’t need additional resources, and areas already struggling likely won’t do better with less resources.

Who would want to start a charter school in an area that has historically struggled, when funding depends on them succeeding immediately?

Seems likely that the new schools would be backed by well funded groups that do t need the funding but want to have a say in what kids are being taught.

hedora•14m ago
The function isn't "winner takes all". It's a claw back after objective failure.

California already spends tons of extra money on stuff like special ed, and struggling districts. I wouldn't touch that.

So, if there's a high school in a struggling area and it's graduating kids that can't do 7th grade math, then that opens up funding for charters in that area at 150% state average per student, or whatever the current formula us.

jeffbee•23m ago
I doubt that you can point to a high school which banned calculus. My guess is that you are referring to a political fight in San Francisco where a very specific racial/ethnic cohort of parents believes that one of the high schools is a Berkeley/Stanford acceptance funnel reserved for them, and they got mad when the government decided to spread the wealth.

From my perspective, there has never been any dumber debate than whether 9th grade math is called "Math" or "Algebra". My kids went to high school in Berkeley where Math is just called Math in grades 9-11 and after that you can take AP Calculus or AP Statistics if you want. And this is not Woke 1.0 stuff because the courses have been named that way forever.

hedora•12m ago
They planned to do it state wide. The ban was blocked. It did not happen.

The results were predictable and predicted but politicians, state and local went whole hog on equity. That along with NCLB results on this catastrophe. We’re finally seeing some needed pushback. You can just hand out As to everyone and pass everyone as it’s a kindergarten assignment. You’re teaching people who will become adults and you’re shortchanging them on skills if you don’t require proficiency. It’s also unfair to apt students who put in the time to learn and do well.

I can’t believe they actually went so far as to dismantle the little haven for achievement that was Lowell high school in SF by getting rid of GPA and entrance exams for a few years. Eventually furious alumni got that idiocy overturned but it should have never happened.

We’re also seeing higher ed address grade inflation by capping As at some institutions of renown.
