This information is taken from https://www.oceg.org/certifications/maintain/
To maintain BOTH GRCP and GRCA certifications you must:
Hold an active All Access Pass (this is a paid membership product)
Complete 8 hours of continuing professional education every calendar year
Continuing professional education (CPE) requirements are WAIVED for the first calendar year. We do this to keep everyone on an easy to manage annual schedule.
So, for example,
if you get certified in January 2020, your first calendar year of required CPE is 2021.
If you get certified in December 2020, your first calendar year of required CPE is 2021.
Also, the 8 hour requirement is for ALL of your certifications. For example, if you have GRCP, then you need 8 hours total. If you have GRCP + GRCA you need 8 hours total.
Something to keep in mind is that all of your activity on the OCEG website is automatically tracked on your certification dashboard. This way, when you view a 30 minute video on the site, you automatically get 30 minutes tracked!
