What is the CPPS pass rate?
Here's the honest answer: the certifying board doesn't publish one. CBPPS has explained that because candidates choose for themselves whether to take a review course, it doesn't report comparative pass rates. It also doesn't publish a numeric passing score or a scaled score range.
That means any specific CPPS pass rate you see online, whether it's 60%, 70% or 80%, isn't coming from the official source. It may be a guess, a figure from a different credential, or a number from a single course's own students. Don't let it shape your plan.
What is published is more useful anyway: exactly how the exam is built and scored. Once you understand that, you know what you need to do to pass.
How the exam is actually scored
You're measured against a standard, not other candidates
CPPS is criterion-referenced. There's no curve. Your result doesn't depend on how anyone else did on the same day. If every candidate in a testing window meets the standard, every candidate passes.
The standard is set by experts, question by question
The passing point is set with a method called the Angoff method. In plain terms, a panel of experienced patient safety professionals reviews each question and estimates how likely a minimally qualified practitioner would be to answer it correctly. Those judgments are combined to set the cut score.
Different exam versions are balanced
Because there are multiple forms of the exam, statistical equating adjusts for small differences in difficulty. You aren't penalized for drawing a slightly harder version.
Only 100 of the 120 questions count
Twenty unscored pretest questions are scattered through the exam, and they aren't labeled. A question that feels strangely obscure might be one of them, but you can't know, so answer everything carefully.
What this means for you
You don't need to beat anyone. You need to consistently choose the answer an experienced safety professional would choose, across all four domains, within the time limit. That's a trainable skill.
Why prepared candidates still fall short
There's no official breakdown of why candidates fail. But the exam's design points to predictable traps, and they're worth planning around.
1. Studying the wrong mix of content
Culture and leadership feel central to patient safety, so candidates often over-study them. Yet Culture is only 20 of 100 scored items. Safety Risks and Responses (35) and Performance Measurement (25) together make up 60%. A plan built on instinct instead of the blueprint can leave the biggest sections underprepared.
2. Knowing terms but not applying them
The handbook states that only a small share of questions test recall. Most describe a situation and ask what to do. Flashcards on definitions won't carry you; you need practice choosing between plausible options.
3. Running out of time
With 120 questions in 150 minutes and no breaks, you get about 75 seconds per question. Long scenarios eat time quickly, and candidates who never practiced under a timer often rush the final section.
4. Answering as a clinician instead of a safety leader
Experienced clinicians sometimes pick the answer that fixes the immediate problem for one patient or holds one person responsible. The exam usually rewards the answer that fixes the system so the problem doesn't recur.
5. Skipping measurement and statistics
Control charts, measure types and variation show up in Domain 4. Candidates without quality-improvement training sometimes hope to get by without them. Remote testers face an extra hurdle: no scratch paper.
6. Overlooking workforce safety
The content outline treats harm to staff, including workplace violence, incivility and support for staff after adverse events, as core material. Candidates who study only patient harm miss those questions.
Practice with timed, scenario-based questions that mirror the real exam format.

These habits line up directly with how the exam is built:
- They study from the official content outline. It's free and it defines the test. Everything else is supplementary.
- They weight their time by the blueprint. Roughly a third of study time goes to Safety Risks and Responses, a quarter to measurement and analysis.
- They do a lot of scenario questions. Hundreds, not dozens, with time spent on why each wrong answer is wrong.
- They take at least one full timed simulation. 120 questions, 150 minutes, no breaks, ideally twice.
- They track results by domain. An overall score hides weaknesses. A 90% in Culture can mask a 55% in measurement.
- They learn a few decision rules cold. Just culture categories, the hierarchy of action strength, when to use RCA vs. apparent cause analysis vs. FMEA, and common-cause vs. special-cause variation.
- They review guesses, not just misses. A correct guess is a gap that happened to go your way.

If you don't pass: the retake rules
| Rule | Details |
|---|---|
| Waiting period | 30 days between attempts |
| Attempt limit | Up to 3 attempts within one year |
| After a third unsuccessful attempt | Wait one year before trying again |
| Cost | A new application and the full exam fee each time |
If you do need to retake, don't simply reread the same material. Use your score report and your practice results to find the domains that cost you, then rebuild your plan around those.
Are you ready? A self-check
You're in good shape to schedule if you can say yes to most of these:
- I've read the full official content outline at least once.
- I've completed at least one timed, full-length practice exam and finished on time.
- My practice scores are consistent across all four domains, with no domain lagging far behind.
- I can explain the difference between human error, at-risk behavior and reckless behavior.
- I can rank corrective actions from strongest to weakest.
- I can read a control chart and spot a special-cause signal.
- I know when an event calls for RCA, apparent cause analysis, or FMEA.
If a few of those are shaky, give yourself another week or two. Rescheduling is cheaper than a retake.
Frequently asked questions
CBPPS doesn't publish a pass rate. It has said that because review course participation is self-selected, it doesn't report comparative pass rates. Treat any specific figure you see online with caution.
CBPPS doesn't publish a numeric passing score. The cut score is set with the Angoff method, in which expert reviewers judge each question, and equating keeps different exam forms fair.
No. It's criterion-referenced, so you're measured against a fixed standard rather than against other candidates.
After 30 days. You can attempt it up to three times in one year, and each attempt requires a new application and the full fee.
It's challenging mainly because most questions test application rather than recall and the pace is tight at about 75 seconds per question. Blueprint-weighted study and timed scenario practice address both.
