Continuing education requirements can be different for each certification agency. But the premise is the same, all certifiers require that continued competence be demonstrated through CE. For your participation in CE, you receive Continuing Education Credits (CECs).
CECs are required for personal trainer recertification. You have to get CECs in order to keep your CPT credential (because losing it will affect your job, your insurance policy, and your reputation – we’ll help make sure that doesn’t happen)!
