Yes. Starting in 2014, in preparation for the release of the Fourth Edition of the INCOSE Handbook, the Certification Program began offering the knowledge exam at conferences and in classrooms for the purpose of testing new exam questions. This marked the beginning of a test-first approach, although it was initially limited to these paper-based, classroom exams. 

In 2021, INCOSE is offering internet-based testing. Candidates will still need to register with INCOSE before taking the exam. They will then be able to schedule the knowledge exam online.  They will be limited to three (3) attempts per 12 month period.
