So how do we help faculty (and students) to sort out the two, Dave? I have always found it useful to think in terms of whether the proposed accommodation is likely to insure a better grade for the NONdisabled students. For example, providing Braille for a blind student or an interpreter for a deaf student is necessary for ACCESS Providing those same things for the nondisabled student would not be likely to improve their grade. Waiving a class because the student's disability interferes? That could border on being a success-oriented strategy (something other students could use as well). That's why we rarely offer waivers, only substitutions.
