AAFCS certification - is it worth the time investment for an FCS teacher?

I've been going back and forth on whether to pursue the AAFCS certification for about a year now. I teach high school family and consumer sciences and my district doesn't require it, but a few colleagues who have it say it opened doors for curriculum leadership roles. Curious if others here felt the payoff was worth the prep time.

From what I've gathered, the exam covers six content areas - human development, personal finance, nutrition and food science, textiles, housing, and consumer economics. I'm comfortable in most of them but the personal finance section sounds like it has real depth to it, covering tax strategy and investment vehicles that go well beyond what I teach day to day.

I've been looking at the study materials and it seems like 12-15 weeks of steady prep is realistic if you're already working in the field. Someone told me the passing rate for first-time test takers is around 68%, which is lower than I expected given that most candidates are practicing professionals.

Did anyone find particular content areas harder than expected? I'm most nervous about the consumer economics questions because that's the area I've had the least formal coursework in.
