Psychology is doing their best, it's just that their best isn't great compared to most other modern medicine. At this point, autism is still held by many in the same way it was in the 90s, only the negative traits, as some developmental disorder, etc. Some of the best tests compare the average answers to questions like that from previously diagnosed autistic people and non-autistic people. The way we think is so different, I'd wager studies would find this sort of difference with anything they asked, assuming they asked the question in a certain way and the autistic person gave the first answer that came to mind instead of the answer they'd give when masking. That doesn't make the test invalid, it just proves how profoundly different the neurotypes are.
Autism wouldn't be a disorder if everyone had the neurotype. The label is still strongly attached to the diagnosis given to people with this neurotype who also have severe mental disabilities. People still resist giving the diagnosis to high functioning adults, which muddies the field's ability to study the neurotype and throws off all the statistics.
Counterpoint, most of the stuff I learned in my highschool A+ class (aimed at teaching you enough to pass a certification test that proves you can repair computers) was outdated already that year, and it's like 95% outdated now. Typing and business productivity app skills are still directly valuable for most modern people.
Most valuable skills are things like learning how to learn, critical thinking, judgement, understanding the value of time, humility, etc. I'll say that the A+ course was much better than most classes at growing those skills for me, but I could say the same thing about the construction course I took. American school system, at least when I was in it, is totally happy to output kids that only know math, science, english, and arts. It's hard to teach those life skills, harder to test for them, do we just don't.
