How to Get CRCST Certification: Step by Step

1 Step 1: Choose your credential

The two national sterile processing credentials are HSPA's CRCST and CBSPD's certification. Most candidates pick based on what local job postings name and what nearby employers prefer, since both are respected nationally. Six states require certification by law, so check your state's rules first: that alone may decide for you. Our CRCST vs CBSPD comparison lays out the differences side by side.

Once you have chosen, read HSPA's Certification Handbook and the CRCST exam content outline. These two free documents are the entire blueprint: eligibility, policies, every topic, and every domain weight. Everything from here on is execution.

2 Step 2: Secure your 400 hours

This is the longest lead time in the whole process, so it comes first. You need 400 hours of hands-on work in a real sterile processing department: 120 in decontamination, 120 in preparing and packaging, 120 in sterilization and disinfection, 24 in storage and distribution, and 16 in quality assurance. Paid employment and volunteer work both count; every hour must be verified by an SPD manager or supervisor.

HSPA does not place candidates, so the search is yours: apply for SPD aide or trainee postings, ask hospitals about volunteer or practicum spots, and start early. At full-time pace the hours take about ten weeks, but the search itself can take longer than the hours. Do not wait until you feel "ready" to start looking.

3 Step 3: Study while you earn the hours

The hours and the studying reinforce each other, so run them in parallel, not in sequence. While you are learning decontamination on the job, study the cleaning and decontamination domain. While you assemble trays, study preparation and packaging. The exam tests judgment built through real instrument handling, and candidates who connect the reading to the work remember far more.

Weight your study time by the domain weights: roughly two-thirds of your hours on the three 21% domains. Finish every study week with mixed practice questions, and track your misses by domain so the weak areas get the attention. Our how to pass guide turns this into a week-by-week plan.

4 Step 4: Apply to HSPA

Submit your certification application to HSPA with your documentation. Allow three to four weeks for processing, so apply before you need the testing window, not after. The application fee is $140, covering processing and one exam attempt. Double-check that your name on the application matches your photo ID exactly, because Prometric will compare them on test day.

If your 400 hours are documented, you are on the full-certification route. If not, you can still apply and test under the provisional route, which gives you six months from your exam date to finish and document the hours. Just be certain you can secure those hours, because missing the provisional deadline means reapplying and retesting.

5 Step 5: Schedule at Prometric

After approval, HSPA emails your scheduling instructions and your 120-day testing window begins. You book your own appointment at a Prometric test center; HSPA does not schedule for you. Book within the first 45 days for the best pick of dates, and choose a time of day when you are sharpest. If plans change, Prometric requires rescheduling no later than noon EST three business days before the appointment.

6 Step 6: Pass the exam

Test day is 150 multiple-choice questions in 3 hours: 125 scored, 25 unscored pretest items you cannot identify, so answer everything. Arrive at least 30 minutes early with valid photo ID matching your scheduling letter. Pace yourself at about 72 seconds per question, mark and return to the hard ones, and trust your preparation. Results come back as pass or fail. Our exam day tips guide covers the full test-center playbook.

7 Step 7: Finish the hours and hold the credential

Pass with your hours already documented and you receive full CRCST certification. Pass under the provisional route and you have six months from your exam date to complete and document the 400 hours, so finish strong and file the paperwork early. Then protect the investment: HSPA requires recertification on a cycle with continuing education, and a lapsed credential surrenders the hiring and advancement advantages you just earned.
