It is wise to check with the registration boards before registering for teacher training courses eg: Yoga Alliance and in Australia Yoga Teachers Association of Australia. Schools may claim to be registered but this doesn't mean it is so! Knoff Yoga in Queensland, Australia has been recently discovered to have made false claims about their school being registered with Yoga Teachers Association of Australia. It is not! These considerations are very important when choosing a teacher training course as it affects a teachers insurance! Not everyone in the yoga industry is honest. This is an industry like any other so watch out for frauds and less than honest operators. Do you homework before handing over your money!
