504
504 is the educational code for special needs students. schools are required to give such students certain forms of aid according to their level and classification, as decided by testing.
A student who is 504-severe ADHD can request notes from teachers, be given extra time for assignments, and even be exempted from assignments, depending on school policy and the student's test results.
