The Certified Registered Central Service Technician (CRCST) credential is offered by the Healthcare Sterile Processing Association (HSPA). This guide summarizes the public facts you need to plan your preparation. Always confirm details on HSPA's official website before you register, because policies and fees change.

Format

The exam has 150 multiple-choice questions, of which 125 are scored (the others are pretest items), with a 3-hour time limit. It is offered in English. That is 72 seconds per question. Our free readiness check gives you 50 questions in 60 minutes, the same pace.

What is tested

The November 2023 content outline weights the seven domains as follows:

DomainWeight
D1 Departmental Considerations15%
D2 Cleaning, Decontamination and Disinfection21%
D3 Preparation and Packaging21%
D4 Sterilization Process21%
D5 Sterile Storage, Transport and Inventory Management9%
D6 Patient Care Equipment and Distribution5%
D7 Professional Development and Human Relation Skills8%

Almost two thirds of the exam (63%) comes from D2, D3 and D4. Spend most of your time there, but do not skip D7: medical terminology and instrument names are quick points.

Fee and eligibility

HSPA lists a $140 exam fee for initial and retake attempts. Full certification requires 400 hours of hands-on experience in a sterile processing department; HSPA allows candidates to take the exam first and complete the hours within 6 months afterward (provisional status). Part of the fee ($25) is non-refundable. Check HSPA's current rules for your situation.

A simple 4-week plan

  1. Week 1: take the free readiness check and read your domain breakdown.
  2. Week 2: study your two weakest domains; drill 20 questions a day.
  3. Week 3: cover D2-D4 fully; review every missed question and its explanation.
  4. Week 4: take the full-length 150-question timed practice exam; aim for a steady 80%+ before booking.

How the CRCST tests this

Every domain is tested in proportion to its weight. Scenario questions are common: they describe a situation and ask for the best next step, so learn the reason behind each rule.
