Testing Online

When you arrive at a testing location, a proctor will access the online testing site. You will then see the home page of www.natetesting.com.

You will then click on “Take a NATE test online” and¬†enter the Proctor ID number and the Session ID number, both of which you will receive from the proctor. You will then be asked to enter your NATE ID and PIN number to proceed. If this is your first time taking a NATE exam, you will create your own data record in the NATE system.¬† You will then be able to create a PIN and you will be given a NATE ID. Please make note of both numbers.

After you have completed the test, you will see on screen whether you passed or failed.
