CCP exam — worth it for someone already in PR for 5 years?

I've been in communications and public relations for about five years now, mostly on the agency side, and I'm considering sitting for the CCP. My main hesitation is that I'm not sure whether the credential actually moves the needle for hiring managers or if it's more of a personal milestone thing. Anyone who's gotten it recently have thoughts on how employers responded?

The content domains I've looked at seem reasonable — media relations, crisis communications, organizational communications, digital and social strategy. Honestly I feel pretty solid on most of those from real-world experience. It's the formal writing standards and the ethics sections where I think I'd need to brush up, since those don't come up as explicitly in agency day-to-day work.

I've been told the exam is about 150 questions with a three-hour time limit, and the passing score is around 70%. Some people I've talked to said they studied for six to eight weeks and felt over-prepared, others said they underestimated the measurement and analytics section and had to retake. So the variability in prep time seems high depending on your background.

If you went through the process, I'd really want to know: did it change your job title, salary negotiation position, or the types of clients you could pitch to? That's ultimately the decision point for me more than the content itself.
