Upon Certification

Once you complete all these steps, the INCOSE Certification Office will send you a congratulatory email. Your e-certificate will come from Accredible. You may also check your certification status through your member profile on the INCOSE web page.   

The ESEP certification is valid so long as you maintain your INCOSE individual membership. You are expected to continue your professional development but are not required to submit documentation of it to INCOSE. 



How long does the ESEP review process take? 

Our review and processing typically takes two to three months. The review starts once all of an applicant’s materials, including references and proof of degree, are received. If the review team have questions, you may be emailed to provide clarification. In this case the review team waits until the candidate submits an update. The longest delay in an ESEP review is the scheduling of interview with the applicant and, if necessary, references.

During busy times of year, particularly when our volunteers are unavailable due to holidays, reviews may take longer. Candidates concerned about delays in their review should check their member profile at to see if all references have been received.

For how long is an ESEP certification valid? 

An Expert Systems Engineering Professional Certification is valid for the duration of an individual’s INCOSE membership. No certification renewal is required. 

Are the interview questions for ESEP similar to the exam questions for ASEP and CSEP? 

No, the interview is about an individual’s technical leadership experience, not a knowledge check of the INCOSE Systems Engineering Handbook. 

Where should the reference forms be submitted ?

You have to provide information to your References on where to find the reference form (Form 4B). Once the form is filled, please have your References submit Form 4B directly to
