ISC2 has introduced an additional path to earning
the ISSAP, ISSEP and ISSMP certifications. This new path removes the CISSP as a requirement, while recognizing seven years of relevant experience as a qualifying factor in earning the ISSAP, ISSEP or ISSMP.
There are now two ways to earn and maintain these specialized, role-based certifications. Learn more at ISC2 Insights: https://www.isc2.org/Insights/2023/10/Additional-Non-CISSP-Path-to-ISSAP-ISSEP-and-ISSMP-Certificati...
I would have to look it up and have never done it on my exams, but I believe that you might be able to claim up to 40 hours of study time for a certification on the ISC2 list. I earned my ISSEP last year and ISSMP this year. I had plenty of CPEs and have never claimed study time. The only organization that I know of for sure that just renews certifications if pass higher ones is CompTIA, and ISC2 is much better than them in recognition and respect. Hope that you work it out. Definitely read the NIST documents for the ISSEP. I did see announcements on the concentrations being able to stand on their own. BrightTalk has informational webinars on those changes. I might suggest that you concentrate on ISC2 BrightTalk webinars as if give your member #, ISC2 applies your CPEs automatically. This also means that they are not subject to audit. I think is a great way to get CPEs and keep current.
You can claim a reasonable amount of study time as CPEs. To give an idea, I did the ISSMP and claimed maybe 20 hours, then the ISSAP and claimed maybe a similar amount. The evidence I used was that I'd actually passed the exams, as you'd be unlikely to pass without doing at least some study. Last cycle I used the CCSK study as part of my CPEs. That's a pretty straight forward exam about cloud, so if you're 10 or 15 hours adrift on your CPE total may be worth looking at. Again the cert is good evidence that you've done the study.
