CII activities are overseen by a Secretariat comprised of representative members of its founding organisations. The Secretariat is defined and guided by the CII Bylaws.

The Secretariat’s role is to facilitate the exchange of information between CII participating organizations and to promote the harmonisation of best practices.

The Secretariat arranges and oversees the staging of the CII’s annual conference, selects its host, provides guidance on the development of the conference agenda, and provides continuity between conferences and rotating hosts. It has the final authority on the conference’s date, venue, participants, agenda, presenters, and matters requiring the endorsement of conference participants.

The Secretariat also guides the CII’s strategic direction, approves the pursuit of new projects by CII participants to harmonise practices, maintains the CII website, and amends the CII Bylaws, as deemed necessary and appropriate from time-to-time.

The Secretariat is comprised of representatives from the investigative offices of three permanent members, the current and immediate past conference hosts, and additional members as appointed by the Secretariat for one-year renewable terms.
