This seems to be a universal problem and certainly one I experience every day. So literally before dinner was over I built the first version of this site on my phone with Claude.
I think the main problem is that the folks who are responsible for communication just don't have the tools and experience to know what good communication really looks like, or the parents perspective hasn't been demonstrated to them to give them more empathy. So I am hoping this can help. Feel free to share if you have the same problem with your school.
