At the beginning of every semester students registered with SDS may request a letter for each of their classes that verifies the disability and appropriate accommodations. The student hand delivers the letter to the instructor, giving the student an opportunity to discuss the nature of the disability and any needs related to that class. SDS professional staff are available to the instructor for consultation if needed. Instructors are not obligated to do any accommodations until an Accommodation Request Form is requested and subsequently a letter from SDS is hand delivered to your instructor each semester. Accommodations are not retroactive.
