Guerda,
I would be happy with all of your solutions except the first one, Guerda. One of the cardinal principles of making accommodation is that it should never translate to requiring LESS of a student. All your other suggestions are ways of giving the student the same test, under different circumstances. Testing over less content wouldn't be a good idea. OH! Unless you meant breaking the test -- the SAME test -- into smaller segments and testing over all the same materials but in smaller units. That would work in some classes, not others.
