PTCB scores: 1,400 passes, on a 1,000–1,600 scale
Updated
The PTCE reports a scaled score from 1,000 to 1,600; you pass at 1,400. It is not a percentage — 80 of your 90 questions are scored, and PTCB publishes no conversion between questions missed and the number on your report. Here’s what it does mean.

Score estimator
Estimated scaled score
≈1,420
right at the passing line
An estimate, not a conversion — PTCB has never published a raw-to-scaled mapping, and each exam form is equated separately. This uses the same piecewise map as our diagnostic report; the anchors and their reasoning are public on the methodology page.
1,400 is not 87.5% — how scaled scoring works
Dividing 1,400 by 1,600 and calling it a percentage is the most repeated mistake about this exam. The scale starts at 1,000, not zero, and the mapping from raw answers to the scale is not linear — so the arithmetic has no meaning.
What actually happens: expert panels set the passing standard with the modified-Angoff method — estimating, question by question, how many just-qualified technicians would answer correctly. Because PTCB runs multiple exam forms that differ slightly in difficulty, forms are equated (IRT pre-equating), and your score is reported on the common 1,000–1,600 scale. A 1,400 on a harder form and a 1,400 on an easier form represent the same ability.
The practical consequence: chase mastery of the four domains, not a magic percent-correct. On practice tests, we use the anchors on our methodology page to place you on the scale honestly, error band included.
Your number, and what to do next
| Score | Result | What happens next |
|---|---|---|
| 1,000–1,399 | Not passed | Reapply once your official score posts — no wait for attempts 2–3, and each attempt is a fresh $129. Your report’s domain feedback says where the points went; drill that domain before rebooking. |
| 1,400+ | Passed | Official results post in approximately one to three weeks; your CPhT certificate and wallet card become downloadable in your PTCB account, and renewal comes due every two years. |
Retake rules, verified against PTCB’s Retake Policy v1.2 (March 2025): no waiting period for your second and third attempts; a 6-month wait before a fourth; after four, PTCB requires approved evidence of preparation.
Searching a 0–400 score? That’s the certificate scale
PTCB’s assessment-based certificate exams (immunization administration, medication history, and the rest) use a different scale entirely: 0–400, passing at 300, with results available immediately. If your score report shows a number near 300, you took a certificate exam — the PTCE itself always reports on the 1,000–1,600 scale.
Common questions
What is a good score on the PTCB exam?
Anything at or above 1,400 — the exam is pass/fail, and employers see the credential, not the number. Scores well above the line mostly tell you your margin of safety was comfortable. Below 1,400, the domain breakdown on your report is the useful part: it says what to drill before a retake.
What does a 1,400 on the PTCE mean?
It means you met the passing standard exactly. 1,400 is the scaled passing score PTCB’s expert panels set using the modified-Angoff method — it is not a percentage and not a question count. Every form is equated so 1,400 represents the same ability level regardless of which questions you drew.
What is the highest score on the PTCB exam?
1,600. The scale runs 1,000–1,600, so 1,000 is the floor, not zero — even a blank exam scores 1,000. A perfect raw performance maps to 1,600.
What percentage do you need to pass the PTCB? How many questions can you miss?
PTCB has never published a percent-correct equivalent or a “questions you can miss” count, and any site quoting one exactly is guessing. Because forms differ slightly in difficulty and are equated, the raw cutoff varies by form. Our practice materials treat roughly 72.5% as the working pass line — an estimate we explain openly on the methodology page.
Is the PTCB exam hard?
69% of attempts passed in 2025, so roughly one in three didn’t — hard enough to respect, not hard enough to fear with honest preparation. The full year-by-year record and why people fail live on the pass-rate page.
