Iyengar Yoga is a type of yoga founded by B.K.S. Iyengar in the 1970s. To become a certified Iyengar yoga teacher, one must have at least two years of Iyengar yoga experience and successfully complete an assessment. The assessment consists of written and practical exams. Once the assessment is passed, the student is required to attend an Iyengar yoga teacher training course. The course covers topics such as anatomy, philosophy, sequencing, and teaching methodology. After the course is completed, the student is required to take an additional assessment and submit a portfolio of teaching experience. Upon successful completion of these steps, the student is awarded a certification as an Iyengar yoga teacher.
