Review Candidate Handbook and Step-by-step Registration Guide

Your Candidate Handbook is your handy guide to answer all the questions you have about submitting an application, scheduling, taking an exam, getting score results, and much more.

We also highly recommend that you read the Step-by-step Candidate Guide with detailed instructions on how to register online for your exam BEFORE you begin the registration process.


Training provider confirms your course completion

Your training provider must send your course completion information to Credentia before you can create an online account and register for testing. Training providers electronically upload your course completion details to Credentia. Ask your training provider when they will submit and verify your course was completed.

IMPORTANT: Please do not attempt to create an online account before you receive an Activation email from Credentia (see step 4 that follows). This will only delay your registration.


Receive Activation email to create your account and register

Upon receipt of your training program information, Credentia will immediately send you an Activation email to create an online account. Please follow the instructions in the Activation email. If you do not receive an email and your training provider has confirmed sending your information to Credentia, please check your spam or bulk email folder.

The link provided in the activation email can only be clicked once. You must activate your account before the expiration date listed in the email.

If your notification is not in your junk or spam folder or you have not accessed your account within the allotted time period, please follow the “Account Recovery” process in the Step-by-step Candidate Guide.

If you have already activated your account, log in to schedule a test or change your testing appointment. Do not attempt to login if you have not yet received your Activation email.
