Above-level testing is useful for decisions about:

1. Identifying a student for a gifted program
2. Determining what a student is ready to learn next
3. Deciding whether or not a student is ready for subject-matter acceleration
4. Deciding whether or not a student is ready to skip a grade

“Above-level testing” is exactly what it sounds like: Give a younger student a test that was developed for older students.
