There are a ton of bellydance instruction veers out there too. I learned bellydancing for years before teaching it and continued my education. I took a workshop on teaching bellydance as well. I found that to be enough to teach bellydance. I find these various certs to be moneymaking scams. A pole cert is more legit in that it is a pretty dangerous sport. Anything where you could break your neck, I’d say a certification should be needed.
