Computer Based Testing

Computer-Based Testing Option

Interested in testing but not able to attend a Paper & Pencil administration? Computer-Based Testing (CBT) is an easy choice.

CBT candidates sit for the same COS-C exam as P&P exam participants. It’s up to you to select a date and make the exam appointment.

Exam Details

CBT exams cost $345 for initial testing and $295 for renewal testing. If it has been more than three years since your last exam, your COS-C designation has lapsed and you will need to pay the initial testing rate.

You can schedule your CBT exam at one of over 300 testing centers around the country. Each assessment center is a certified PSI Services testing facility that adheres to the highest administration standards.

Please watch this 3-minute videoᅠfor a quick overview of what to expect during a PSI test center exam session.

Why Choose a CBT Exam?

  • Receive results immediately
  • Gain scheduling flexibility


If you are unable to test at your originally scheduled appointment time, you may reschedule the exam for free one time, at least two business days before the exam date.
