I've also been with NAPMA for over 2 years. They've given me a lot of ideas on how to improve the business side of my school. Not only do I get to network with hundreds of school owners around the world, I get ideas on class drills, advertising, and new class types.
About a third of my school is in a program that they specifically started. I even modified it a little to fit my school and my teaching style. But that's 20 students that I wouldn't have otherwise.
The only gripe I've ever had is that their ad slicks tend to present people in Gi's more often than not which differs from my Chinese art roots. But, I get their pictures on disk so I can change the ad as I want to so I don't complain too much.
As far as the cost goes, I thought long and hard about whether I should stay with them or not. I wondered if I'd gotten to the point where I soaked up enough material from them and could save the monthly expense. Then I realized if I sign up 2 people based on their advice, I more than break even. To me, then, it's worth it.
