 The Wheel ran yoga teacher training programmes and accredited the programmes of other organisations.By the 21st century, yoga teaching in Britain had changed from mainly publicly funded (by local education authorities) to mainly private, whether in small local groups, advertised classes in venues such as church halls (often British Wheel of Yoga), organised groups like Iyengar Yoga, Ashtanga Vinyasa Yoga and Bikram Yoga, or commercial studios providing many different styles of yoga.A 2019 project bringing yoga into schools has had "a profound impact" on Norfolk primary school children with special needs such as attention deficit hyperactivity disorder and autism.
