I agree that ceiling on the number of credentials won’t make the profession exclusive. Maybe “exclusive” is not the right word. My point is part of the reputation and the honor of being an actuary comes from the credential because it’s hard to get, and not many people get it (or if you’d like to say it’s the ego, that’s fine). The job market also makes it clear that salaries and promotions are to some degree tied to the credentials, even though passing one more exam doesn’t mean you’re better at your job. So what I’m trying to say is that those exams and credentials make this career a bit different from similar professions. When it’s different in a good way, it’s partially due to the very difficulty of getting the credentials.
