What are the best colleges for  dyslexia?

The answer to this question depends on student interests, faculty:student

ratio, support services for learning disabilities / differences,
flexibility in curriculum, and the severity of dyslexia-related
challenges.

Some students may only require writing support from their university's writing center, where as others will require more
supports, meeting regularly with a tutor or counselor, reduced
courseload, and a full range of assistive technologies. Some students also choose a 2 year college transitional program instead of enrolling in a conventional curriculum but seeking outside support from on campus disability resources.

students for work and/or higher education during the junior and
