Citing laws that govern vocational schools, like those for hairdressers and truck drivers, regulators have begun to require licenses for yoga schools that train instructors, with all the fees, inspections and paperwork that entails. While confrontations have played out differently in different states, threats of shutdowns and fines have, in some cases, been met with accusations of power grabs and religious infringement — disputes that seem far removed from the meditative world yoga calls to mind.
The conflict started in January when a Virginia official directed regulators from more than a dozen states to an online national registry of schools that teach yoga and, in the words of a Kansas official, earn a “handsome income.” Until then, only a few states had been aware of the registry and had acted to regulate yoga instruction, though courses in other disciplines like massage therapy have long been subject to oversight.
