A Systems Engineering Professional Certification is valid for a period of three years. It is renewable for three-year periods. The actual period will commence on the date that INCOSE issues the initial certification. For a renewal application to be valid and processed, it must be dated (electronic or post marked) no later than the expiration date of the current certification. For example, if the applicant received his/her certification on August 16, 2005, then his/her certification expires on August 15, 2008; and the renewal application must be dated (electronic or post marked) no later than August 15, 2008. Renewal applications that are dated (electronic or post marked) after the expiration of the current certification will not be processed; the applicant will have to repeat the entire certification process to regain CSEP status.

Applications for triennial renewal of existing certifications are made by using the renewal form and following the instructions provided under the Forms section.Renewal requires confirmation of attaining 120 professional development units (PDUs) of continuing education during the prior three years. (See the Continuing Education section for guidance on acceptable sources of education credit.)
