I don't know if this has anything to do with autism (I'm not autistic), but I would like for schools to allow students to focus on one subject at a time. Instead of four semesters where they have to simultaneously study language, math, science, and history, have one semester devoted exclusively to each of those.
There are several colleges that do this, calling it the block plan. The ones I know of are Cornell College, Colorado College, and Quest University.
Smith College is considering trying to make itself more attractive to smart students on the autism spectrum. I would be grateful for suggestions on how to do this from autistics who read LessWrong. You can write comments here or if you wish to remain anonymous send them to me at Jdmiller@Smith.edu
