Test Day

You should arrive at the testing center about 30 minutes before your scheduled exam to allow extra time for the check-in process. If you arrive later than the listed reporting time on your admission ticket, you will not be able to take the exam and your testing fees will be forfeited.

During the check-in process, you will be asked to provide at least one form of valid identification, which must contain your photo and signature.

You should also receive an unofficial score report right after the exam. Your official report will be made available about three weeks after the testing window closes.

Passing Score

The Georgia Professional Standards Commission (GaPSC), along with local education committees, established the minimum passing scores for the GACE content assessments:

  • 220-249: Induction level
  • 250: Professional level

If you take the combined test and one of your scores is at the induction level and the other is at the professional level, you will be considered as having only passed at the induction level.
