Certification for Testers and Specialists

On this Page:

The Department issues certification cards for Testers and Specialists on a 2-year certification cycle. Certifications expire on December 31st every two years based upon the first letter in the last name of the individual. Individuals with a last name beginning with A-K expire in even numbered years, and individuals with last names beginning with L-Z expire in odd numbered years.

New applicants will receive cards that expire less than 2 years from the issue date, depending on when they apply. The $195.00 fee is prorated to $97.50 for the last 12 months, or less, of the certification cycle.

If any of your contact information changes it is your responsibility to contact the Program with these changes. Failure to notify the Program of an address change will result in delayed renewal and in some cases lapsed certifications.
