ACE CPT Passing Score: What a Scaled 500 Means, Your Results Screen and a Retake

The ACE CPT passing score: a scaled 500 on a 200–800 scale

ACE's Certification and Recertification Handbook (revised September 2026) states the rule for the NCCA-accredited exam: your score "is derived from the number of questions answered correctly, and is then converted to a scaled score ranging from 200 to 800 points, with the passing point set at a scaled score of 500 points." Candidates at 500 or above earn the certification.

Three facts frame that number:

• Only scored items count. The exam has 150 questions, but the 25 experimental ones don't enter your score. The 125 scored items do.
• Only the scaled score decides. The handbook says, "Only the scaled score determines pass/fail status." There's no separate minimum per domain.
• 500 is not 50%. It's the midpoint of the scale, not a percentage of questions answered correctly.

This applies to the accredited ACE Certified Personal Trainer Exam. The open-book certificate exam is scored differently, with a plain 70% pass mark.

Why ACE publishes no "number correct" for the ACE CPT

Not every candidate sees the same questions. ACE builds several exam forms to the same blueprint, and the handbook says that "since items differ in terms of how easy or hard they are, different test versions may not be equally difficult." To keep the standard fair, ACE adjusts the passing point so it is equivalent across forms. Meazure Learning's psychometricians do this with a method called item response theory (IRT) equating, which ACE calls an industry standard for larger certification programs, especially those that report scores immediately.

The pass point itself comes from a standard-setting process. Subject matter experts rate each question by estimating the percentage of minimally competent trainers who would answer it correctly, and the cut score is calculated from the overall difficulty. The handbook notes one exception to equating: the very first exam built on a new content outline is set directly by experts at a standard-setting meeting.

The practical consequence: the raw score you need can differ slightly from one form to the next, and ACE doesn't publish it. Some prep sites quote a figure such as 90 of 125 correct. That isn't an ACE number, so don't plan around it. Aim instead for comfortable accuracy across all four domains, since the weights decide where most points come from. You can see how planned ACE CPT practice is weighted across the outline, from 23% for Client Onboarding and Assessments to 31% for Program Design and Implementation.

What you see when you submit the ACE CPT exam

Results are immediate at a test site and online. According to the handbook and ACE's scheduling page:

The handbook is explicit about the domain percentages: they are "provided only as a guide for failed candidates to identify the domains where they have the greatest room to improve." They don't change the result. If you pass with a low percentage in one domain, you still pass.

If you pass but have a CPR audit or payment hold on your account, ACE says the certification won't be issued until the hold is cleared. Once issued, an ACE certification is valid for two years and expires on the last day of the month in which you earned it.

If something went wrong during your ACE CPT exam

• During a live-site exam: tell the proctor immediately, so the complaint is documented. The handbook says to also contact ACE Exam Registration within 30 days to explain how the issue affected you. ACE's scheduling page asks for an email within 24 hours of the exam, so report it the same day.
• During an online exam: technical problems that stopped you from finishing need a ticket with Meazure Learning within 48 hours, through its intake form.
• If you didn't pass and think scoring went wrong: you can request a manual rescore within 30 days of the exam. The fee is $50, and Meazure Learning reports the result within two to four weeks. The handbook is candid that a manual rescore "rarely, if ever" changes the outcome.

If your ACE CPT score is below 500

A score under 500 is a "failed" status, and you can sit the exam again. ACE's rules:

• Fee. $249 for a retake within one year of your first attempt. After that year, the first-time fee applies again.
• Earliest date. ACE's pages disagree. The scheduling FAQ and the Exam Options page say as soon as four days after the failed attempt. The post-exam section of the scheduling page says as soon as 10 days. Plan on 10 and confirm when you book.
• Retake vouchers. If you bought one with a study program, you must use it to register within 60 days of the failed exam. The exam date can be later.
• Delivery. You can switch between a test site and the online exam for the retake.

ACE also gives a planning rule in ACE Answers: allow about one week of review for every 10 points you were below 500. ACE's own example is a 480, which suggests about two weeks. Applied to other scores, the same rule gives:

Treat that as a minimum. ACE's advice is to schedule "within a realistic timeframe" based on how far you were from the passing point, to work hardest on the domains with the lowest percentages while still reviewing the others, and to compare your report with the content outline domain by domain. The free ACE CPT retake planner asks you to rate each domain from your score report, then builds a week-by-week plan up to your retake date. Before you book, test yourself under exam conditions once more: a 150-question mock exam is planned for full ACE CPT prep, scored at the end.

How many people pass the ACE CPT?

ACE's handbook reports that 73% of the 7,105 Personal Trainer candidates who took the certification exam in 2025 passed. What that figure does and doesn't tell you is covered in how hard is the ACE CPT exam.
