Based in mainland Europe, W.I.D.A. organizes workshops, competitions and examinations to aid in the promotion of an interest and the development of a standard in Irish Dancing.W.I.D.A is aware that competition and the shows have become the focus of what Irish dancing is today but we want to make it clear that in W.I.D.A - fun, friendship and the passing on of knowledge are more important.
