The activities that usually count
Most certifying bodies accept a familiar set of continuing-education activities: instructor-led training and courses, technical webinars, industry conferences, vendor briefings with substantive content, reading approved books and whitepapers, completing online courses, and giving back through teaching, presenting, writing, or volunteering. As a rule of thumb, one hour of a qualifying activity earns one credit — though passive activities like reading or listening are frequently discounted.
The common thread is that the activity has to teach you something relevant to your certification, and you have to be able to show what you learned. "I attended" is not the same as "I can document substantive content." Bodies care about the second one.
