Certification is valid for three years. Once the certification period has expired, course organisers may re-apply for certification though a simplified application procedure (Download the Simplified Application Form for Renewal of Certification of Courses).

If substantial changes are made to courses that have been granted ENTRi certification, course organisers are obliged to inform ENTRi. This will involve completion of a new application form for the renewal of certification, detailing the changes that have occurred (structure, format, deliverers, major changes to course content). (Download the Application Form for Certification).
