One of the most valuable services you can offer your members is continuing education and training. In today’s competitive world, knowledge is critical to success. NATE tests validate training that associations offer by providing independent third-party results.

Association Partner Testing Organizations and Proctors

Any HVACR industry association or chapter of an industry association can become a NATE Testing Organization (TO) to administer NATE tests. For additional information on becoming a Testing Organization, go to Testing Organizations and Proctors.

Associations and their chapters that wish to participate need to fill out the Testing Organization Application and Proctor Application and return them to NATE.

Once applications are approved and you have received your ID numbers, you may then schedule a test and order exams. See Getting Started as a Testing Organization

Note: Every NATE test session requires a proctor. A proctor is any individual who takes responsibility as the primary point of information for the testing organization. Proctors handle test oversight at the testing facility, read the proctor test script to all test sessions, are responsible for all test security, and are responsible for returning tests with-in 48 hours of completion of the test session to VGI/NATE Testing by a means of shipment which can be tracked.
