Test Dates

CST certification exams are no longer scheduled on specific dates. They’re by appointment only. Testing centers have their own schedules, but most are available twice a day, 6 days a week.

Application Process

Applications may be submitted by mail or online.

Once you submit your application, allow 6 weeks for processing and receipt of your Authorization to Test (ATT) letter. You must have an ATT letter before scheduling your exam. For a $50 fee, you may request rush processing that’s guaranteed to get your ATT letter sent to you within 3 to 5 days of application receipt.

The rush processing fee is on top of the $190 for AST members or $290 for non-members for the exam. If you choose rush processing, you must pay by credit/debit card or money order. The NBSTSA doesn’t refund application fees for ineligible applicants.

Exams are provided by appointment only. You must apply and be determined eligible to sit for the exam before making an appointment to test at a testing agency near you.

If you fail your exam, there’s no waiting period to test again. However, you can only take the exam three times per year and must submit a new application and exam fee on each attempt.

CST certification needs to be renewed every two years. Methods for renewal include earning and submitting the required continuing education (CE) credits to AST and submitting a renewal application to the NBSTSA or retaking and passing the national certifying examination through the NBSTSA.

Renewal Fees

Renewal fees will be refunded to ineligible applicants, minus a processing fee and rush processing fee if applicable.

• Standard Renewal Fee for CE Renewal: $25

Fees for Renewal by Examination:

• $299 for current AST members

• $399 for non-members

CSTs completing a 2-year cycle must earn 30 credits, which include 4 live CE credits. Those still completing a 4-year cycle must earn 60 credits for renewal. All CE credits must be earned through AST-approved sources. CSTs may also renew their credential through testing instead of submitting CE credits to the AST.

• Earn CE through the AST Continuing Education Resource Center or visit the Continuing Education Policies for the CST for more ways to earn CE

• Use the AST CE Reporting Form to submit CE credits

• Consider submitting required CE credits 60 days before credential expiration to any
