CRAH has been formed to act as a Register of Advanced Hypnotherapists. The majority of members are likely to be graduates of the National School of Hypnosis and Psychotherapy Ltd (N-SHAP). It has replaced the Central Register of Advanced Hypnotherapists which originally was the administrative arm of N-SHAP under the guidance of Polly Roche-Pengelly and Ray Keedy-Lilley.

Applications for membership from experienced practitioners from other appropriate training schools / colleges would be welcomed.
