Preparation Strategies

The following strategy will help ensure proper preparation for attempting the certification examination: 

1. Familiarize yourself with the exam objectives: Make sure you understand what the exam covers by reviewing the exam objectives. You can find the exam objectives on the certification provider’s website.

2. Review the recommended study materials: The certification provider usually offers study materials that cover the exam objectives. These materials may include books, training courses, or online resources.

3. Opt for an online course: Although it is not compulsory to register for the CSPDT course, it can help you pass the exam. Online courses tend to be preferred over offline ones, as most offline courses are pretty rigid, and you must alter your schedule according to the class timing. Online courses are quite flexible, and you can choose your preferred class times. Additionally, all your study material is saved on a cloud drive that you can access at any time. 

4. Create a study plan: Create a study plan based on the time you have available before the exam. Break the material down into manageable sections and allocate time for each section.

5. Practice with sample questions: Use sample questions or practice exams to get a feel for the type of questions you can expect on the exam. This will help you to identify areas where you need to focus your study efforts.

6. Join a study group or discussion forum: Join a study group or discussion forum to learn from others preparing for the exam. You can share study tips, ask questions, and discuss difficult concepts.
7. Review regularly: Review regularly to reinforce what you have learned. This will help you retain information and ensures you are prepared for the exam.

Recertification fee: $135.

Technical Facts

Eligibility Criteria

CBSPD eligibility is based on meeting at least one approved pathway by the application deadline. Candidates must be able to read, write, speak, and understand English, since the exam is offered in English.

Eligible pathways typically include one of the following:

• 12 months of full-time employment (or equivalent part-time hours) in sterile processing and distribution activities, verified on the exam application.
• Completion of an SPD training course with a passing grade of 70 or higher, verified by course documentation.
• Related allied healthcare work plus SPD activities with at least 6 months of full-time employment (or equivalent part-time hours), verified on the exam application.
• 12 months of healthcare product sales or service work related to the SPD profession, verified on the exam application.

CSPDT vs. CRCST

Certification	Issued by	Exam structure	Practical experience requirement	Validity
CSPDT (Certified Sterile Processing and Distribution Technician)	Certification Board for Sterile Processing and Distribution (CBSPD)	150 multiple-choice questions in 3 hours	Eligibility is met through one of several accepted pathways	5 years
CRCST (Certified Registered Central Service Technician)	Healthcare Sterile Processing Association (HSPA; formerly IAHCSMM)	150 multiple-choice questions in 3 hours	400 hours of hands-on experience (and other requirements set by HSPA)	5 years

CSPDT and CRCST are two different sterile processing certifications offered by different organizations. While both cover core sterile processing knowledge (such as decontamination, inspection, packaging, sterilization, and distribution), they differ in eligibility rules and certification requirements. Always confirm the current requirements for the credential you plan to pursue before applying.

Language and Geography

The exam is offered in English, and candidates are expected to have sufficient English proficiency to take the test. Reasonable accommodations may be available for eligible candidates when requested and approved in advance.

Computer-based testing is typically provided through an approved testing provider. In locations where computer-based testing is not available, testing may be offered in an alternate format at an approved site, based on program availability and local arrangements.

Results Scale and Interpretations

Exam Scores and Result Delivery Method

To pass the CSPDT certification exam, candidates must meet the scaled passing standard set by CBSPD. Results for computer-based testing are provided after the exam is completed. Passing candidates receive a pass result and are issued a certificate and ID number after the exam window closes. Candidates who do not pass receive a diagnostic report showing performance by content area.

When paper-and-pencil testing is used in locations where computer-based testing is not available, results are sent after the exam window and can take longer to process. For security reasons, final results are not released by phone or email.

Raw and Scaled Scores

CBSPD administers multiple versions of the exam. Because forms can differ slightly in difficulty, CBSPD uses a scaled score so results are comparable across forms. A scaled score at or above the passing standard is reported as pass, and a scaled score below the passing standard is reported as fail.

Determining Cut Score

The passing standard is set using a standard-setting process designed to reflect the performance of a minimally competent technician. Subject matter experts review exam content and recommended standards, and psychometric analysis is used to support fair scoring across exam forms.

FAQs

CSPDT Test Tips

Following are a few tips that may prove helpful on the exam day:

1. Study regularly: Studying regularly over a longer period can be more effective than cramming right before the exam. Make a study schedule and stick to it to cover all the material thoroughly.

2. Take care of yourself: Get enough sleep and eat healthy foods in the days leading up to the exam. Being well-rested and alert can help you perform better on the exam.

3. Arrive early and be prepared: On exam day, arrive early to allow time to get settled and mentally prepared. Bring all necessary materials, such as identification and any permitted items, and follow the exam rules and regulations.

4. Take advantage of the CBSPD Technician Study Guide: The CBSPD has developed a study guide to aid individuals in preparing for the Technician Certification Examination. This guide comprehensively covers all content areas and includes a discussion on test-taking techniques and sample questions. It should be noted that the study guide is not intended to serve as a textbook.

5. Effectively manage your time: You will have limited time to complete the exam, so it is important to manage your time effectively.

6. Read instructions carefully: Take your time and read all instructions carefully before beginning the exam. Doing so will ensure that you understand what is expected of you. It will help you avoid mistakes or misunderstandings.
7. Stay focused and manage your time: During the exam, be focused and manage time wisely. Answer the questions you know first. Go back to the more challenging ones later. Do not spend too much time on a single question. Avoid rushing through the exam.
