In 2007 I received the Iyengar yoga Introductory Certificate. In 2017 I received certification at Junior Intermediate Level 3.
All teachers are trained in the Iyengar tradition and are certificated by the IYA (UK). This entitles them to use the Iyengar Certification Mark: an indication of high quality training endorsed by BKS Iyengar in Pune, India.
The process of training and assessment is repeated with higher standards at six additional levels of certification, from Introductory to Intermediate Senior. Each level taking a couple of years minimum.
