Candidates must wait 45 days before retaking the same test/subtest. For tests that include subtests (i.e., Communication and Literacy Skills, General Curriculum, and the Vocational Technical Literacy Skills Test), you may take one or both subtests at a given test session. Once you meet the passing score on a subtest, you do not have to take that subtest again. Candidates should not retake a test prior to receiving their test results from that test.
