Several Steering Groups have been established in IPPOG in order to steer different concrete activities and projects (in which case their mandate might be limited to the duration of the project). These bodies serve for guidance and advice to the Coordinators of the activities and projects.  Today IPPOG has International Masterclasses Steering Group, Global Cosmics Steering Group, IPPOG Web Development Steering Group and IPPOG Resource Database Curation Group.
