Certification Exam Pass Rate Calculator

Calculate pass rate, failure rate, first-time pass rate, and retake statistics for certification exams — useful for training programs, HR departments, and individual candidates.

Total Candidates Who Took the Exam

Number of Candidates Who Passed

First-Time Takers (optional)

First-Time Takers Who Passed (optional)

Passing Score (%) — Minimum to Pass

Average Candidate Score (%) (optional)

#### Formulas Used

Overall Pass Rate: Pass Rate (%) = (Number of Candidates Passed ÷ Total Candidates) × 100

Failure Rate: Failure Rate (%) = 100 − Pass Rate (%)

First-Time Pass Rate: First-Time Pass Rate (%) = (First-Time Takers Who Passed ÷ Total First-Time Takers) × 100

Retake Pass Rate: Retake Takers = Total Candidates − First-Time Takers Retake Passed = Total Passed − First-Time Passed Retake Pass Rate (%) = (Retake Passed ÷ Retake Takers) × 100

Score Gap: Score Gap = Average Candidate Score (%) − Passing Score Threshold (%) A positive gap indicates the average candidate scored above the threshold; negative indicates below.
