Dual registration is when a counsellor, for professional or other reasons, has chosen to belong to two or more professional bodies in their field. It is possible, for example, for a nurse or a doctor who are on a medical register to train in counselling or psychotherapy and thus be on registers in two different but allied fields. Below is a list of other professional bodies:
Association of Child Psychotherapists
