Or worse yet, go undetected.
I was out of college before I realized I had been pushing upstream for my entire school career. My partner had gotten identified and gotten help, it wasn't easy but much easier.
I had always tested very highly on standardized tests but was a horrible student. My mom would tie me to chairs, my teachers would verbally abuse me, all of it. Not to mention the social issues I had.
It's a relief to know now, but it leaves me wondering how differently my life would've turned out had someone thought to test and accommodate. Even now I am just kind of not really sure what to do with the knowledge, beyond not guilt-tripping myself for being more "normal".
Other forms of preparation for life: social skills; financial skills; political engagement; health, are rarely prioritised.
Giving autistic children help with academic learning and disruptive behaviour is conventional, as it is for all students (albeit with special measures and allowances made). Other life skills are neglected, as they are for all students.
What is today's social contract?
I really have no idea.
This is the situation I was in at school/college/university. Meanwhile when you leave education, the same situation applies there too; the organisations and resources seem to mostly be focused on making sure someone on the spectrum is employed/not homeless, with zero real thought towards their general wellbeing.
