Hosting Practical Exams



The person designated by their company or organization to liaise with CCO on the test administration matters is know as the Test Site Coordinator. The Test Site Coordinator is responsible for:

  • Submitting all required information to CCO in a timely fashion on the Practical Examination Test Site Application Form (and Data Sheet, where applicable)
  • Preparing a test area in accordance with the directions in the Test Site Setup and Test Site Layout Instructions provided by CCO
  • Preparing test equipment in accordance with the directions in the Practical Test Site Coordinator Handbook
  • Notifying CCO of the intention to test; this notification must be sent via the CCO website at no less than two business days (not including weekends or holidays) prior to testing; Test Site Coordinators must also notify CCO if testing plans change; once a site has provided test notification to CCO, this will be considered intent to test and the site may be audited even if no testing occurs
  • Scheduling candidates to take the practical exam and informing them of their test date, location, and time
  • Liaising with the Practical Exam Proctor and CCO in all aspects of test preparation and administration
  • Ensuring that the Test Site Coordinator or a designated representative remains on site throughout each test administration
  • It is the responsibility of the Practical Exam Proctor to submit score sheets; Test Site Coordinators may not have access to completed score sheets


The practical examination is conducted by a CCO-credentialed Practical Exam Proctor. A Proctor may test only one candidate on one piece of equipment at one time.

Thus, testing a candidate, or several candidates in turn, on one piece of equipment would require one Practical Exam Proctor. Testing two candidates simultaneously on separate pieces of equipment would require two Proctors, and so on. If you need assistance on selecting a Practical Exam Proctor, contact CCO.

Practical Exam Proctors print personalized candidate score sheets from the CCO website as needed; they are required to bring an adequate supply of score sheets for all candidates to be tested, including extras for any retests. 


Assistant Proctors are volunteers who assist the Practical Exam Proctor in the administration of exams. The Test Site Coordinator is responsible for assigning one Assistant Proctor per Practical Exam Proctor to assist during the test. Assistant Proctors are under the direction of the Proctor during the test administration. Candidates waiting to take the practical exam are permitted to serve as Assistant Proctors during operator practical exams. Assistant Proctor responsibilities include:

  • Assisting the Proctor in keeping the test site configured accurately (e.g., barrel placement, Zigzag Corridor setup, Right Angle Corridor setup)
  • Hooking and unhooking the chains, test weight, etc.
  • Accurately timing all of the tasks as a backup to the Proctor

Assistant Proctors must not give any verbal instructions to the candidates during the actual test administration, nor do any recording on the candidate score sheet.
