Candidate applications are valid for 2 years from the date of approval. If a candidate allows their eligibility to lapse, they can re-apply by submitting a short application form within 1 year of their eligibility expiration date. If the candidate’s eligibility is expired for more than 1 year, a new application must be submitted. When submitting the short or a full application, the candidate will include the full certification fee as payment for the examination.
