About this exam

This page supports candidates preparing for the RSP examination. Before you build a study plan, one limitation must be stated plainly: the official source retrieved for this profile (2026-10-31) documents only the NASP/IASP, Inc. Certification Program - the Master Safety Professional (MSP)® and Certified Safety Director (CSD)® credentials - and contains no reference to an examination designated "RSP." No RSP item count, time limit, passing score, fee, or validity period can therefore be reported here, and the domain weights published alongside this page are a provisional placeholder that must be replaced with the official RSP blueprint before it is relied on.

What the source does document is a family of credentials for practicing workplace safety professionals, accredited by the ANSI National Accreditation Board under ISO/IEC 17024:2012, examined by a three-hour, 150-question computer-based proctored test scored on a 200–800 scale with a minimum passing score of 500. Treat those CSD and MSP figures strictly as reference points, not as RSP values. Confirm your own exam's blueprint, eligibility track, and fee schedule directly with the certifying body before scheduling, and re-verify every number on this page against the current candidate handbook.

Common questions

About RSP preparation

Does the source behind this page confirm any RSP exam details?

No. The retrieved source covers only the NASP/IASP, Inc. CSD and MSP certifications and never mentions an RSP examination. Item count, time limit, passing score, fees, and validity for RSP are therefore reported as unknown rather than estimated. Verify RSP specifics with the certifying body's own handbook before scheduling.

What exam format is documented for the CSD and MSP?

Both are closed-book, proctored, computer-based tests delivered through a third-party contractor, either at an onsite testing center or via online proctoring. Each consists of 150 multiple-choice questions with a three-hour limit, and each form includes a few unscored questions used to gather statistics for future test forms. Those items do not count toward your score.

What is the passing score, and how is it set?

A panel of subject matter experts reviewed each examination with a psychometrician and applied classical test theory equating to set the passing point. The minimum passing score is 500 on a scale where the maximum possible score is 800 and the minimum possible score is 200. Your score report appears on screen at completion and is emailed to you.

Can I retake the exam if I fail?

Yes - one retake within your eligibility period. You must wait thirty days from the date of your first examination before sitting for the retake, and the option appears in your student portal once that period passes. If you do not pass after two attempts, you may reapply as a new applicant one year after your last exam date, meeting all requirements and paying fees again.

How long is my eligibility window once approved?

You must purchase an exam option, register, and sit within one year of your eligibility approval date. Within the final 60 days you may buy a 90-day extension. Miss the deadline and you must reapply for eligibility and pay all applicable fees again. Applications themselves must be submitted within one year of creation or the data is deleted.

What fees are documented, and are they refundable?

For CSD: a $75 application fee plus a $395 examination fee that includes two exam attempts, with a $195 recertification fee due at the end of the three-year cycle. For MSP: $75 application, $450 examination fee including two attempts, and a $250 recertification fee. All fees are non-transferable, non-refundable, and subject to change.

What does recertification require?

Certificants complete 4.8 CEUs or semester hours over a three-year cycle - 1.6 per year - which equals 48 hours of contact time, or 16 hours per year. One CEU equals ten hours of instruction and one recertification point; one semester hour equals one CEU. A 180-day grace period exists, but CEUs earned during it do not carry into the next cycle.

How should I sequence my study time?

Follow the published blueprint rather than studying all topics equally. The CSD blueprint devotes 39.28% to laws and standards and only 3.71% to science and mathematics; the MSP blueprint gives 42.44% and 4.10% respectively. If your exam mirrors that profile, weight regulatory and consensus-standard content heaviest and treat calculation topics as a smaller, targeted block.

How should I manage time during a three-hour, 150-question exam?

You have roughly 1.2 minutes per question. Flag and skip anything requiring long computation on the first pass, bank the quick recall items, then return with the remaining time. Practicing under a timer with full-length sets is the most reliable way to find your personal pace before test day.

How long does application review take?

The certification board notifies applicants within 7–10 business days with one of three outcomes: approved eligibility, additional information required, or denied eligibility. Build that window into your timeline so approval, exam purchase, and scheduling all fit inside your one-year eligibility period.
