Online Proctored Testing (OPT)

Online Proctored Testing (OPT) allows candidates, once scheduled, to take CCO written exam(s) online using their own internet-connected computer from almost anywhere, 24/7/365! Benefits of OPT include:

  • Greater flexibility in scheduling and rescheduling
  • Immediate score reporting*
  • No late application or rescheduling fees

* Preliminary results will be available immediately. All results and test administration are subject to review and approval following standard testing protocols.

What Does OPT Look Like?

Candidates take exams via a computer in a private, well-lit room with a door and that is void of any materials (i.e., electronic devices, books, papers, etc.) on the table or desk.

Exams that require supplements (e.g., load charts) or calculators have these available on-screen. In place of scratch paper, candidates may use a physical whiteboard/dry erase board up to 8.5 in. x 11 in. or an on-screen whiteboard that is built into the exam. 

CCO has prepared a video demonstrating how the testing platform works:

Through the myCCO Portal, candidates have access to a demo exam at no cost. This demo exam is intended to provide a test simulation experience. Candidates have the opportunity to familiarize themselves with how to navigate through the exam and utilize the on-screen tools, including:

OPT Computer Requirements

OPT exams may be taken on any laptop or desktop computer that meets minimum technical requirements. In order to test via OPT, the computer must be equipped with:

  • A microphone
  • A webcam

Want to check to see if your computer meets requirements?
