Yes, unless the requirement would tend to discriminate against the person by necessitating behavior which is significantly impeded or precluded by the disability. In the latter case, such criteria can only be required when their removal or modification would constitute a substantial alteration of the fundamental elements of the course (including certification and/or licensure requirements), or if they were to constitute an undue financial or administrative hardship. Although the criteria for denial are rigorous, the "undue hardship" criterion is especially difficult to utilize. All courses have essential knowledge and skills which must be mastered and evaluated. If a learning disability prevents a student from demonstrating knowledge and mastery, an alternative, instructional or evaluative strategy may be developed, or an accommodation may be arranged that is not required of other students.
