Sleep technologist certification, for the people who set up, monitor and score overnight sleep studies, centers on the registry credential of the Board of Registered Polysomnographic Technologists. You get there with supervised clinical time in polysomnography or an accredited program, a healthcare life-support card, and a passed exam of 175 questions at a test center. Below are the steps, the time they take, and how the five sleep credentials you are likely to meet (RPSGT, CPSGT, CCSH, RRT-SDS, RST) relate to one another.

How to become a sleep technologist: training, hours, exam
- Pick a training route. The school route is a polysomnography program accredited by CAAHEP or CoARC, on its own or added to a respiratory therapy or neurodiagnostic program. The job route means working in a sleep lab under supervision while you complete the STAR education program. Licensed clinicians, such as nurses and respiratory therapists, can use their existing credential in place of STAR.
- Log the clinical time. Every route except the accredited program asks for 960 h of clinical polysomnography, that is, recording and scoring real studies, logged within the 3 years before you test.
- Check your life-support card. BRPT wants a healthcare-provider BLS or CPR card, and the class behind it must have tested your skills in person; cards from purely online classes stopped counting.
- Apply and sit the exam. You file the application online with the board and pay the $550 fee with it; once it is approved you book a Pearson VUE center. The exam facts page explains length and scoring.
- Keep it current. The credential renews every 5 years with continuing education; see renewal.
How long does it take to become a sleep tech? On the job route, the clinical requirement sets the pace. At 36 hours a week, 960 h takes about 27 weeks, a little over six months, before you add the education module and the application review. A program runs as long as its curriculum, and its graduates apply without an hour count.
The registry exam in numbers
RPSGT vs CPSGT vs CCSH vs RRT-SDS vs RST
| Fact | Detail | Source |
|---|---|---|
| CPSGT | BRPT's entry-level certificate, valid for 3 years, with 10 sleep-focused CECs required each year. The CPSGT does not qualify you for RPSGT Pathway 2. | BRPT: CPSGT credential page [4][8][9] |
| CCSH | BRPT's Certified Clinical Sleep Health credential, renewed every 5 years | BRPT: CCSH credential page [10] |
| RRT-SDS | NBRC's Sleep Disorders Specialty exam, open only to Certified (CRT) or Registered (RRT) Respiratory Therapists. A CRT must hold the credential for at least six months and an RRT for at least three, unless a CoARC respiratory therapy program with a sleep add-on track was completed. The exam costs $300 for new applicants. | Sleep Disorders Specialty (SDS) examination [11] |
| RST | The American Board of Sleep Medicine gave its last Registered Sleep Technologist exam from April 4 to May 2, 2022 and keeps active RST credentials until December 31, 2032. BRPT accepts the RST as a healthcare credential for RPSGT Pathway 2. | ABSM to discontinue Registered Sleep Technologist exam [4][12] |
| RPSGT | The registry credential for technologists who perform and score sleep studies; renewed every 5 years. | BRPT, RPSGT |
Of these five, only the registry exam has its own pages here; the others are described from their boards' pages.
CPSGT or RPSGT: which comes first?
The CPSGT is the certificate for the start of a career: you are in or just out of sleep education, with early clinical time, and you work under supervision. It is time-limited (see the table), and BRPT expects its holders to move up. The registry credential is the full one, earned on clinical hours or an accredited program.
One detail settles the route. As the table notes, the entry certificate does not open Pathway 2, so a holder reaches the registry exam like any technologist trained at work, with clinical hours plus STAR education or through an accredited program. Holding the certificate shows an employer you are in the field, but it takes nothing off the hour count.
Coming from nursing or respiratory therapy
Licensed clinicians use the credential pathway, Pathway 2: the same 960 h of clinical polysomnography, with the healthcare credential standing in for STAR education. BRPT's list covers nursing licenses, the CRT and RRT, neurodiagnostic credentials, physician assistants, physicians and paramedics; the credential overview has the full list.
A respiratory therapist has a second option in the NBRC's sleep disorders specialty, written RRT-SDS or CRT-SDS. It is an add-on to an RT credential from a different board and a separate exam, not a version of BRPT's registry. Which of the two a sleep lab asks for is stated in its job posting.
RST is not the BRPT registry
A search for registered sleep technologist leads to the RST, the American Board of Sleep Medicine credential, not to BRPT; its current status is in the table above. A source that says the registry credential comes from ABSM has the two boards mixed up.

Becoming a sleep technologist: short answers
How long does it take to become a sleep technologist?
On the job route, the time goes mostly into logging 960 h of clinical polysomnography: about six months at 36 hours a week, plus the STAR module and the application review. An accredited program sets its own length, and its graduates apply without counting hours.
Do I need the CPSGT before sitting the registry exam?
No. The entry certificate is optional, and BRPT does not accept it as a Pathway 2 credential, so it neither replaces nor shortens the clinical hours.
Can new candidates still earn the RST?
No. ABSM no longer offers the exam, and active RST credentials end on December 31, 2032. Holders can move to BRPT's registry through the credential pathway.
Can a respiratory therapist work toward sleep certification?
Yes, two ways. The RRT or CRT is an accepted credential for BRPT's Pathway 2, with the same clinical hours as everyone else, and the NBRC offers its own sleep disorders specialty to RTs.
