Independent Feldenkrais Trainings

There are numerous Feldenkrais trainings not associated with Feldenkrais Guilds. They differ in various points such as time frame and costs, but most prominently in that graduation from these trainings DOES NOT give graduates the right to use any of FGNA’s trademarks, service marks, certification marks, logos, and trade names (such as Feldenkrais®, Feldenkrais Method®, Guild Certified Feldenkrais Teacher®, Awareness Through Movement®, ATM®, Functional Integration®, FI®, GCFT(CM), Feldenkrais Practitioner(CM), GCFP(CM), etc.) in any form, other than as part of the phrase “Dr. Moshe Feldenkrais.” There are special crossover policy for graduates from some of them (like Eli Wadler’s or early Mia Segal’s trainings) to join national associations of Feldenkrais teachers (guilds) as full member, in some countries such graduates can join as assosiate member without any special requerements (e.g. Switzerland or Belgium).

Most of graduates from this trainings in Europe join alternative proffesional assosiation Feldenkrais Network International.
