If a student previously tested via On-Campus (Residual) or any other non-national testing, the retest should be taken on a National ACT date. If this is not possible, test takers may retake the ACT On-Campus Test. A minimum of 60 days must elapse before another Residual ACT test may be taken. ACT restricts the number of times a student may take the ACT (National or Residual) to 12 times total. Scores achieved before the minimum elapsed time and scores that exceed the maximum total attempts will be cancelled without refund.
