Pass mark

NPPE pass mark: what "65" actually means

The single most misunderstood number on the NPPE. Short version: 65 is a scaled score, not a percentage. Here is why that distinction matters for how you study.

Last updated

The NPPE pass mark is a scaled score of 65, not 65% of questions answered correctly. It is a statistically equated figure, set independently of how many raw questions you got right.

Scaled score, not raw percentage

The NPPE Candidate Guide states the pass mark as a scaled/equated score of 65, not 65% of the questions you answered correctly. The exam uses statistical equating across sittings, so a candidate who wrote a slightly harder version of the exam is not penalized relative to one who wrote a slightly easier version. In plain terms: nobody outside the NPPE program can tell you exactly how many of the 100 scored questions you needed to get right, because the conversion is not published and can vary by sitting.

Why this exists: the Modified-Angoff method

The NPPE sets its standard using a Modified-Angoff process: subject-matter experts review every question and estimate what proportion of minimally competent candidates would answer it correctly. Those judgments are combined into a cut score for that sitting, which is then reported on a fixed 0-100 scale where 65 is always the pass mark, even though the underlying raw-score threshold that produces a 65 can differ slightly from sitting to sitting.

Criterion-referenced, not curved to a quota

The NPPE is criterion-referenced: there is no fixed percentage of candidates who are allowed to pass. Every candidate, first-time or repeat, is held to the same standard. This is different from a strict "curve" that guarantees, say, the top 70% pass regardless of absolute performance.

If you pass

You receive a pass/fail result. Passing candidates do not currently receive a section-by-section breakdown.

If you don't pass

You receive an Individual Mastery Report showing Mastered / Borderline Mastered / Not Mastered for each of the six blueprint sections, and retake the entire exam, covering every section again.

No manual rescoring

Because the NPPE is entirely multiple choice with your answers captured automatically, per the NPPE candidate guide there is no manual rescoring process to request: your recorded answers are your result, with no separate step where a person re-marks your exam.

See the full exam format, the syllabus by section, or try our results calculator for a rough, unofficial estimate of a weighted score (it cannot replicate the real scaled score, since that formula isn't public).

Frequently asked questions

Is the NPPE pass mark 65%?
No. 65 is a scaled, equated score, not a raw percentage of the 110 (or 100 scored) questions you answered correctly. The NPPE program has not published the exact raw-to-scaled conversion.See the results calculator.
What is the Modified-Angoff method?
It is a standard-setting technique where subject-matter experts estimate, question by question, how a "minimally competent" candidate would perform. Those estimates set the difficulty-adjusted bar each sitting has to clear, which is then expressed as a scaled score: 65 on the NPPE.
Do I need 65% in every blueprint section?
No. The pass mark is a single overall scaled score across the whole exam, not a per-section minimum. But if you don't pass, the Individual Mastery Report you receive does break your result down by blueprint section, labelling each as Mastered (about 70%+ correct in that section), Borderline Mastered (about 55-69%), or Not Mastered (below about 55%).See the section by section syllabus.
