Hi Michelle,
In order to take the TECEP you will need to get your TESU website login from your coach and create a login for ProctorU so that you can set up a time for the proctored exam. Once you log in to TESU's website you should see the TECEP test waiting for you there. But you will only be able to access the study guide information. the Proctor will enter in the codes for you to take the actual test. Good luck!
The myDegree website may also have some really great study information to help you prepare for the TECEP you will take.
