Your NATE Certification will need to be renewed every two years. There are two ways for a technician to complete this task. First, you can complete 16 hours of continuing education during the two year period and pay a recertification fee. The second option is to retake the specialty exam that you originally took prior to the two year expiration date. For further clarification of recertification, you can check NATE’s FAQ page on the matter as well.
