how many ceu’s are recieved for completing the NCSF certification?

I do not know of many CPT certs that accept other CPT certs for CECs. You already have a CPT cert, why would that be consider “continuing” education to retake an exam to get a different CPT cert?

In any case, you may as well contact NASM to see if you can use it. Since you apparently have already taken the course. You have nothing to lose if they say it doesn’t qualify.
