Step 2: Review the GateWay exam dates & locations. Available Exam Dates: All Locations tab.

Step 3: Pre-order your exam using the NEW Purplepass System – You no longer need to create a Maricopa Student Account. (Purplepass only accepts credit cards as payment). See ‘Exam Information’ tab for details.

Step 4: After passing your exam – Apply for your new or upgraded certificate with ADEQ.  Simply complete a New Certificate Application, provide a copy of your test results, and pay a $65 fee.
