Some decisions in IPPOG are being taken by different committees or after consultation with advisory boards. These bodies serve for guidance and advice to the Coordination team, Collaboration board or Collaboration as a whole. These groups are based on standing or recurrent need of IPPOG Collaboration for their input.

Today IPPOG has two permanent Committees: the IPPOG Finance and Audit Advisory Board (IFAAB) and the Speakers and Publications Committee (SPC).  Two others are reactivated when needed: the Chair Search Committee and the Scientific Secretary Selection Committee.
