Today there are more than 800 Waldorf schools in over 40 countries. In North America there are over 150 schools affiliated with the Association of Waldorf Schools of North America, and several public schools using Waldorf methods to enrich their teaching. There are also over 50 full-time Waldorf teacher-training institutes around the world; of these eight are in the United States and one in Canada. No two schools are identical; each is administratively independent. Nevertheless, a visitor would recognize many characteristics common to them all.
