Authorised training institutions apply to the Directorate General for endorsement when at most 60 days remain until the five years are completed; the training programmes of institutions that do not apply in time are not approved until the endorsement is completed, and if the endorsement is not completed within three months of the end of the period the authorisation is cancelled (OHS Specialists Regulation, Article 20(2); Workplace Physicians Regulation, Article 27(2)).
