ARB’s Prescription Committee has established a pool of independent advisers from whom it can seek advice on specialist areas of work. Advisers are independent and impartial.  No adviser is asked to advise where there is a conflict of interest or where such a conflict might arise, and they must observe confidentiality at all times.  Advisers can serve for a maximum term of five years, and continued appointment is on an annual basis.
