The use of the name “Iyengar” is protected and may only be used by individuals and associations who are granted permission to do so. IYNAUS, through its regional associations, is responsible for granting permission to certified teachers for commercial use of the Iyengar name. In areas where there is no active regional association, the most senior teacher in the area is authorized to act on IYNAUS’s behalf. In addition, a senior teacher must co-sign with the board representative for all requests made.
