- Exemplar Global/iNARTE does not publish a pass rate for the Product Safety Engineer exam in the sources reviewed.
- The published passing criterion is a 70% average on a 50-question, four-hour, open-book written exam.
- Eligibility screening (STEM evidence plus nine years of assessed experience) filters candidates before they ever test.
- The 25 Examination Topics are unweighted, so no domain is officially "more likely" to dominate your exam.
Why There Is No Official PSE Pass Rate
If you searched for a clean percentage, here is the honest answer: the issuer materials reviewed for this article do not publish one. The iNARTE Personnel Certification Catalog (Product Safety Engineer section, pp. 27-29) and the Exemplar Global certification page describe the exam format, fees, eligibility and renewal. Neither gives a first-attempt pass rate, a cohort size or a historical trend for the Product Safety Engineer credential.
That matters because pass-rate numbers circulating elsewhere on the internet are often borrowed from unrelated exams that happen to share the same acronym. In this article, "PSE" means Product Safety Engineer, the Exemplar Global/iNARTE credential, and nothing else. Any percentage you see attached to "PSE" without a citation to Exemplar Global should be treated as unverified for this credential.
So what can a data-minded candidate actually do? Work with what is published: the exam's structure, its passing criterion, and the eligibility gate. Together these tell you more about your realistic odds than a recycled statistic would. For the broader picture of difficulty, see our guide on how hard the PSE exam is.
What the Issuer Does Publish
Here is the complete set of verifiable exam-outcome facts, drawn from the Exemplar Global page and the iNARTE catalog:
| Item | Published detail |
|---|---|
| Exam format | Written, 50 multiple-choice questions |
| Time allowed | Four hours |
| Passing criterion | 70% average |
| Reference rules | Open book / open notes |
| Calculator | Scientific calculator allowed |
| Results turnaround | Within 10 working days |
| Retake wait | 90 days |
| Published pass rate | Not published in the sources reviewed |
For a deeper look at the scoring line, read PSE Passing Score: exactly what you need to pass. Note the wording "70% average passing criterion": the issuer's phrasing is what you should plan around, and the exact scoring mechanics beyond that phrase are not detailed in the retrieved sources.
How to Read Any Pass Rate Claim
Since no authoritative figure exists in the reviewed sources, you will likely encounter secondhand claims from forums, training vendors or aggregator sites. Run each through four questions:
- Which credential? Does the claim name Exemplar Global/iNARTE and the Product Safety Engineer certification specifically, or just "PSE"?
- Which level? Engineer, Associate and Technician tracks differ. Combined Engineer/Technician statistics say little about the Engineer exam alone.
- Which region and form? Equivalence between regional and global exam forms is not verified.
- What denominator? Is it first-attempt candidates, all attempts, or only people who finished a training course?
A pass rate computed only among people who bought a particular course says nothing about the general population. And because the credential requires years of qualifying experience, the typical candidate is a working engineer, which makes comparisons with entry-level exams misleading in both directions.
How the Exam Format Shapes Outcomes
Open book changes what "hard" means
An open-book, open-notes exam rewards organization and retrieval, not rote recall. With 50 questions and four hours, you have roughly five minutes per question on average, which is generous compared with many certification exams. The time pressure is lower; the risk shifts to misreading what a question asks and not finding the relevant clause fast enough when a question turns on a specific standard or definition.
Why 50 questions raises the stakes per item
With only 50 items covering 25 Examination Topics, each question carries meaningful weight, and it is plausible that some topics appear only once or not at all on a given form. The issuer does not publish topic percentages or a dated exam-form identifier, so you cannot predict coverage. That argues for breadth: shallow gaps in several topics hurt more than one deep gap, because you cannot know which topics your form samples.
Calculator and quantitative work
A scientific calculator is permitted. Topics such as creepage, limits on heat and limits on fuel invite numerical reasoning, so practice working through calculations with the exact calculator you will bring. Familiarity beats a fancier model.
Key Takeaway
Open-book does not mean easy. Build a tabbed, indexed reference set before exam day, and rehearse looking things up under a timer so lookup speed is a trained skill, not a hope.
The Eligibility Filter Before You Ever Sit the Exam
Perhaps the most important "data point" for pass-rate thinking is who is allowed to test. The catalog requires STEM college/university transcript or diploma evidence, a current resume, an ethics agreement and qualifying engineering experience assessed against nine years. Experience credits work like this:
- Four years for an accredited four-year engineering qualification
- One year per satisfactorily completed accredited engineering year
- Two years for a BSET
- Up to one year for engineering postgraduate study
- Up to two years for qualifying teaching
- Combined education/teaching credit capped at five years
- Other curricula individually evaluated
The Credly badge summary mentions a relevant four-year STEM degree or equivalent plus nine years of experience. Read that alongside the catalog's credit rules rather than as nine additional post-degree years. Full details are in our PSE requirements guide.
The implication: the candidate pool is pre-screened by education and experience. Applicants have already shown exposure to engineering practice, so the exam is testing professional-level product safety knowledge, not whether you can handle basic engineering concepts. That is why a headline pass rate, even if one existed, would be hard to compare with open-enrollment exams.
Fees you will actually pay
Published Engineer fees are $50 for application, $260 for certification and $150 for annual renewal. The $310 initial figure is a calculated sum of application plus certification, not a separately quoted exam-only fee. The issuer does not explicitly label the currency as USD, and no member/non-member split is published. Because the retake wait is 90 days, a failed attempt costs you time more visibly than it costs you a clearly quoted separate retake fee in the sources reviewed. See the PSE certification cost breakdown for the full picture.
Where Candidates Lose Points: The 25 Topics
The issuer publishes 25 Examination Topics. They are unweighted and are not a preparation curriculum or a weighted blueprint, so any claim that "Topic X is 20% of the exam" is unsupported. What we can do is group them by the kind of reasoning they demand, which helps you see where a well-rounded engineer might still have a blind spot. Our complete guide to all 25 content areas goes topic by topic.
Cluster 1: Electrical hazard fundamentals
Topics: Connection to supply, Isolation of supply, Earthing, Types of Insulation, Protection against electrical shock, Insulation damage, Creepage.
- Expect questions that hinge on definitions and the relationship between insulation type and shock protection.
- Creepage is a frequent stumbling block for engineers whose daily work is software or systems rather than hardware safety; the global catalog's wording is what matters, not regional variants.
- Earthing and isolation questions reward clear conceptual separation of functional versus protective roles.
Cluster 2: Fire, heat and physical hazards
Topics: Mechanical hazards, Resistance to fire, Fire hazards, Limits on fuel, Limits on heat.
- Distinguish resistance to fire (material and enclosure behavior) from fire hazards (ignition sources and propagation).
- Limits on fuel and limits on heat often involve quantities and thresholds, a place where the calculator and your indexed notes both earn their keep.
- Mechanical hazards cover physical injury risks that electrically focused candidates tend to under-study.
Cluster 3: Design and analysis methods
Topics: Inter system and intra system design, Equipment design, Hazard analysis, Risk assessment, Design review.
- These reward process thinking: how hazards are identified, rated and reduced across a design.
- Experienced engineers often do well here but can lose points by answering from company habit rather than the standard method the question implies.
Cluster 4: Regulation, conformity and documentation
Topics: Legislation US, EEC and International; Military and Civil Electrical Safety Standards; Safety tests; Assessment authorities; Competent Bodies; Safety certification; Declarations of Conformity; Operating and maintenance instructions and handbooks.
- This cluster is the largest by topic count and the most likely blind spot for engineers who have worked inside one regulatory market.
- Know who does what: assessment authorities versus competent bodies versus the manufacturer issuing a declaration of conformity.
- Documentation questions, including operating and maintenance instructions and handbooks, test whether you treat user-facing safety information as part of the safety design.
A Topic-Sequenced Prep Plan
Rather than generic scheduling, sequence by your weakest cluster first, then rotate. One workable ordering ties each week to specific topics:
Self-audit and reference build
- Score yourself 1-5 on all 25 topics.
- Download the catalog's Product Safety Engineer section (pp. 27-29) and build your tabbed reference binder or digital index.
Electrical fundamentals
- Earthing, insulation types, shock protection, insulation damage, creepage.
- Practice worked calculations with your exam calculator.
Fire, heat and mechanical
- Resistance to fire versus fire hazards; limits on fuel and heat.
- Mechanical hazard identification.
Regulation and conformity
- Legislation (US, EEC, international), assessment authorities, competent bodies, certification, declarations.
- Military and civil electrical safety standards.
Timed mixed practice
- Take full 50-question sets under a four-hour limit using only your open-book materials.
- Review misses by topic and patch the index.
The eight-week length is a suggestion, not an issuer requirement; no mandatory preparation-hour total is published. For the full method, see our PSE study guide, and when you are ready to test yourself, try the practice tests to find which topics need another pass. A one-page refresher is also available in the PSE cheat sheet.
Results, Retakes and Renewal
Results are reported within 10 working days. If you do not reach the 70% average criterion, the published retake wait is 90 days, which is a natural window to rebuild the weakest topic cluster rather than simply re-reading everything. Check the issuer for current scheduling mechanics; our exam dates article summarizes what is and is not verified, including that a separate testing vendor, remote platform or adaptive format has not been confirmed.
After certification, renewal costs $150 annually and requires 30 CPD hours per 12-month certification period with evidence, per the iNARTE Continuing Professional Development Log V8 (June 2023). Whether the credential pays off for you depends on your career path; see whether the PSE certification is worth it and the salary guide.
Key Takeaway
Without a published pass rate, your best predictor of success is topic breadth. Use your 90-day retake window, if you need it, to target the cluster you scored lowest on rather than repeating your strongest areas.
Frequently Asked Questions
No pass rate for the Product Safety Engineer exam is published in the Exemplar Global or iNARTE sources reviewed. The only published outcome criterion is a 70% average passing standard on a 50-question written exam.
Yes. The exam is open book and open notes, and a scientific calculator is allowed. You have four hours for 50 multiple-choice questions, so organizing your reference materials matters as much as memorizing content.
Results are returned within 10 working days. If you do not pass, the published retake wait is 90 days. Confirm current details with Exemplar Global before scheduling.
No. The 25 Examination Topics are issuer-published but unweighted, and no official percentages or highest-weighted topic are given. Plan for broad coverage rather than betting on a single heavy topic.
Not safely. Regional notices, such as Japanese combined Engineer/Technician results, are not global Product Safety Engineer facts, and equivalence between regional and global exam forms is unverified. Be equally cautious with figures attributed to unrelated credentials that share the PSE acronym.
