Our Governance

ICF is governed by its Council, elected from within the Chartered Membership and headed by the President and Vice President. There are two main committees – Executive and the Professional and Educational Standards Committee (PESC). The remit of each is set down in the Laws of the Institute (currently the Professional Standards and Educational Standards are run jointly). In addition, the Council have appointed a Professional Complaints Panel and an Examination Board, both of which operate independently from the Council.
