It depends on the total number of schools your child applies to.
At the College Board, we introduce test scores as one additional factor for refining your list. You can categorize reach, match, and safety schools by comparing your child’s SAT or ACT score to a school’s average score range of last year’s freshman class. Your child’s score is either lower (reach), in the same range (match), or higher (safety) than the average score range of last year’s freshman class.
At minimum, we recommend creating a balanced college list to include 3 reach, 2 match, and 1 safety. If your child applies to more than [x] schools, we recommend adding more reach colleges to increase their chances of getting in to a selective school—and to account for colleges they may not have considered before.
