The INCOSE Certification Program requires verification of SE knowledge as part of the ASEP and CSEP certification levels. This verification is typically performed by passing the knowledge exam. Knowledge may also be verified through Academic Equivalency. 

The most popular way to take the knowledge exam before the pandemic was in a classroom. As the pandemic risks reduce, INCOSE is opening back up to this format. INCOSE chapters may request to host an in-person exam. They need to provide a facility and a proctor. Proctors must be CSEPs or ESEPs who are endorsed by their Chapter President, or members of the international Board of Directors. They must have no conflicts of interest with having access to the exam content. The Certification Program Manager approves all proctors.

Individuals around the world may take the INCOSE knowledge exam online, using their personal computers and web cameras.
