When will I know if I have successfully passed the API exam?
API will give you a preliminary score immediately following your exam – Preliminary Pass, Marginal (too close to call), Preliminary Fail
Marks are not final until all candidate exam challenges have been reviewed by a committee of subject matter experts and adjustments, if any, are made.
Candidates will not be certified until final exam results are released. Final results will be emailed from Prometric 6-8 weeks following the end of the testing window.
If I get a Preliminary Fail or I find out I have not successfully passed the API exam; what do I do?
This preliminary scoring system will help the majority of candidates determine whether they need to submit a reschedule application and continue with their studying efforts.
API gives a candidate 12 consecutive months to pass an exam. Those 12 months start from your first scheduled exam.
