Applying for ISA Certification

Applying for certification is easy!

  • Review the CAP® or CCST® program requirements.
  • Self-certify that you:
    • Are fully compliant with the certification criteria, qualifications and conditions for which you are applying; and
    • Acknowledge that you may be subject to a random verification audit and will fully agree to provide the supporting documents proving your qualification.
  • After paying your exam fee online, you will be emailed a testing eligibility code within 5 to 10 business days.
  • Go to and enter your testing eligibility code.  You can then choose to take your exam at a Prometric electronic testing center near you or schedule one to be remotely proctored via ProProctor.
  • You will receive an email from Prometric confirming your test date and location.
  • Report to the testing center or go online with a photo identification, and the confirmation email you received from Prometric.
  • You will receive your pass/fail results immediately after testing at the Prometric test center or by email if done via ProProctor.

All ISA certification exams are closed book. No reference material may be brought in to the test site. For CCST Levels I and III, Units Conversion Tables will be provided to candidates in either paper format for paper/pencil exams or as part of a PDF file for electronic exams for reference during the examination. Click here to review the Units Conversion Tables.

For international applicants, please note that the validation study for the exams was done in the United States so there may be questions on the exam that reference US standards and codes. For a reference of possible US standards and codes to review for each exam, see below:


Electronic Exam Testing Windows

Each year, the CAP and CCST exams are available electronically during three testing windows. Each exam testing window will have a deadline for applications to be considered for testing in that window. Eligible candidates will only be able to test during the testing windows.

As of 1 January 2011, the candidate eligibility window, or testing window, has been extended to twelve (12) consecutive months. After you have paid your application fee, testing must be completed within your assigned twelve-month testing window which is based on the date that your application fee is paid.

In order to schedule an exam, you will need to pay your application fee by the specified application deadline for your preferred exam testing window. The application deadlines and testing windows are as follows:

Exam Testing Window Exam Application Postmark/Submission Deadline
Window 3: 1 November 2020 – 31 October 2021 15 September 2020
Window 1: 1 March 2021 – 28 February 2022 15 January 2021
Window 2: 1 July 2021 – 30 June 2022 15 May 2021
Window 3: 1 November 2021 – 31 October 2022 15 September 2021


Your first exam testing date and all rescheduling and retesting must be scheduled during the testing window for which you are approved to test. 

You may reschedule your exam by using the Prometric portal and the rescheduled date must be during your approved testing window.

You may retest for a fee per retest as many times as needed within your 12-month exam testing window; however, you must allow thirty (30) days between your exam dates. 
If you do not successfully pass the CAP or CCST exam within your twelve-month testing window, you must reapply for the exam by submitting a new application fee. Afterwards, you will be given a new twelve-month testing window based on your application  payment date.

Special Event Exam Dates

ISA offers our certification exams in a paper/pencil format at some special events. Click the certification program below to see these special paper/pencil exam dates:


Private Exam Sites

ISA certification exams can be scheduled for private sites/companies in the United States and will be administered as paper/pencil exams. Click the following link to review information on scheduling a private test site in the United States.

ATTENTION: Private exams will no longer be scheduled outside the United States.

If you apply for electronic testing and determine that you will take the ISA CCST review course that has a paper/pencil exam the day after the course, you must contact ISA to change your exam format and exam date. If you do not, there will not be materials available for you to test during the paper/pencil exam.

If you have applied for a paper/pencil exam with a review course where the fee for the exam was waived (by completing both the exam application and the separate course registration), and you wish to change to electronic testing, you must notify ISA and send the application fee to ISA to change your exam format. You will then receive an eligibility letter, rather than a confirmation letter, which you will need to schedule your electronic exam. Please be advised that you will be assigned a twelve-month testing window based on the postmark/submission date of your application fee. This means, the next testing window, as outlined above, may not be open immediately after you have completed the review course.
