To register for the CHST exam, you must first create an online BCSP account. Through your account, you can then select “CHST” as your certification of choice and fill out the application. You will be asked to provide your contact information, proof of your BSCP-qualified credential, and your experience and education information.

Once the application is filled out, you will need to submit it along with the $140 application fee.

Once your application is approved, you will have a full year from the date of approval to register and sit for the exam. During registration, you will need to pay the exam fee of $300. You can schedule your exam at any time with Pearson VUE.

Test Day

On the day of your exam, you should arrive at the testing location 15-30 minutes before the exam is set to begin. Once you arrive, you must sign in and present your photo ID to the proctor. You will be photographed and asked to sign a roster and other rule forms.

Personal items are not allowed in the testing room, so they should be left at home or in your car. All electrical devices, including cell phones, are prohibited.

Just before the exam starts, you will receive a brief tutorial on the testing system. You will also be given everything you need to work out any calculations by hand (no calculator will be provided).

How the Exam is Scored

BCSP uses the modified-Angoff method and the Bookmark Standard Setting method to establish the scores for the CHST exam. They use these methods to ensure that your score is based entirely on your testing performance and does not rely on how well other test-takers performed.

You will get your results immediately after completing the exam. As long as you achieve the minimum cumulative score for the entire test, you will have passed, even if you did not pass all four domains individually.

Even though you don’t need to pass each individual domain, your score report will show you how you performed on each one. This is useful for understanding your strengths and weaknesses, especially if you did not pass and need to retake the exam. Currently, the minimum passing score is 140 out of 200.
