BRPT's registry exam allows 180 minutes for 175 questions in multiple choice (four options per question), with 150 of them scored. The pass point is a scaled score of 350 on a 200–500 scale; getting 70 percent of the items right is not the standard.

Exam rules from the BRPT handbook

| Question format | Computer-based multiple choice: each question has four answer options. There is no penalty for a wrong answer, and you can mark questions to review. | RPSGT Candidate Handbook (web page) [1] |
| Questions | 175 questions | RPSGT Candidate Handbook (web page) [1][2] |

| Unscored questions | 25 unscored pretest questions, placed at random | RPSGT Candidate Handbook (web page) [1] |
| Exam time | 180 minutes. Restroom breaks run on the exam clock, while the optional tutorial and closing survey sit outside it. You have 3 minutes to accept the on-screen nondisclosure agreement. | RPSGT Candidate Handbook (web page) [1] |
| How it is scored | Scaled scoring: the cut score is set with a modified bookmark study and every form is equated | RPSGT Candidate Handbook (web page) [1] |
| Passing score | A scaled score of 350 on a 200–500 scale. 350 is a converted cut, not a percent correct; the 70% mark belongs to BRPT's Advanced Titration Certificate. | RPSGT Candidate Handbook (web page) [1] |
| Score report | Pass or fail, with a printed report of competency by domain. The score report is final: there is no hand score or rescore. | RPSGT Candidate Handbook (web page) [1] |
| Wait before a retake | No waiting period. You need a new application and fee, and you cannot reapply until your scheduled exam is done. | RPSGT Candidate Handbook (web page) [1][3] |
| Retake limit | No limit on attempts | BRPT: RPSGT FAQs [3] |
| Retake fee | The full $550 again, with a new application | RPSGT Candidate Handbook (web page) [1][4] |
| Pass rate | 40.1% of candidates passed in 2025 (583 of 1,454). BRPT reports 37.7% for 2024 and 38.7% for 2023; the figures are for all candidates. | RPSGT credential page [5] |
| Content outline in force | Exam form in effect since September 1, 2023. BRPT's own Study Guide (7th edition) is still built on the 2018 blueprint. | RPSGT Candidate Handbook (web page) [1][2] |
| Upcoming change | None announced. BRPT announces new exam forms in its handbook and news (read Nov 11, 2026). | BRPT: RPSGT exam blueprint [2] |
| Scoring rules used | Scoring questions follow the current AASM Manual for the Scoring of Sleep and Related Events. When an item shows RECOMMENDED in bold, answer by universally recommended guidelines and industry standards, such as AASM practice parameters, not by your own lab's protocol. | RPSGT Candidate Handbook (web page) [1] |

350 on a scale, not 70 percent
The registry exam has no percentage pass mark. BRPT fixes the cut through a standard-setting study, a modified bookmark method, and equates every form, so 350 marks an equal standard on every version, even when the count of correct answers behind it differs slightly.
The 70 percent figure that circulates belongs to another BRPT product, the Advanced Titration Certificate, a separate assessment for people who already hold a credential. A practice tool that grades you against 70 percent is giving you a rough guide, not the board's standard.
Pass rates BRPT reports
As reported by the board, 40.1% of candidates passed in 2025 (583 of 1,454). The board's figures for the two years before are close to that (see the table), so about four in ten candidates have passed in each recent year. The numbers count everyone examined together, first attempts and retakes alike.
A candidate who fails leaves with a domain-by-domain report. The board calls the domain levels a guideline whose reliability varies with the number of items, so use it to rank weak areas, not to skip any.
What happens in the testing room
Time spent on the optional tutorial and the end-of-exam survey is not deducted from your exam time, but restroom breaks are. Before the first question you have a few minutes to accept a nondisclosure agreement on screen, and if you do not, the session ends and is treated as a no-show.
Your result and the domain report
The pass/fail notice appears on the testing computer the moment you finish, and a Pearson administrator prints the detailed report before you leave. That report rates your competency in each domain instead of giving a percentage. It is final: the board does not hand-score or rescore an exam.
Retakes: no wait, full fee
You can retest as soon as you like and as often as you need; every attempt is a new application and a new $550. One catch: you cannot file the next application while an exam is still booked, so sit or cancel the scheduled one first.

The registry exam in brief
Are the pretest items marked anywhere?
No. The 25 unscored pretest questions sit at random points in the form, not in a block, so answer each one with full care.
Is the registry exam hard to pass?
By the board's own figures, fewer than half of candidates have passed in each recent year. The breadth is what makes it demanding: scoring rules, instrumentation and PAP titration all carry real weight.
Do I find out on exam day whether I passed?
Yes. Your pass/fail status is displayed the moment you end the session, and the center prints the domain report before you go.
