CMAC certification is free for members of AIS Enterprise clients. If your organization provides the full AIS course library to you for free, you likely qualify for free Enterprise enrollment. Annual renewal of your CMAC certification is also free. You will see whether you qualify for this when you access the CMAC enrollment page through AIS Central.
If you are not a member of an AIS Enterprise client, you qualify for Personal enrollment and the cost for initial enrollment and certification is $395.
The annual certification renewal fee is $95 for Personal enrollment.
