I do have a few comments regarding taking a reduced load:
– First, be sure the student is enrolled in enough courses to be considered a full time student (or financial aid/housing etc. can be lost). Typically a minimum of three courses is required to be full time but it can vary so check with each college. I don’t know if any colleges allow fewer classes for full time students with disabilities so you can check on that as well.
– We did pay for my S to take a few summer classes (which he got pre-approved by his college) to lessen his load a bit during the school year. He took classes which would be most time intensive for him (two heavy reading/writing classes and one required lab class).
–IMO it is important to not only pay attention to the number of classes by also the type of classes. My S attended a college with a large core curriculum but we encouraged him to schedule no more than 2 reading/writing intensive classes per semester. Once he got more into the coursework in the business school (which was in his “academic wheelhouse”) he could handle five classes much more easily.
