IPD is the professional development service serving GSA and HMC members. In 2008-09 it will also be working in association with SHMIS. IPD exists to provide high quality training and development opportunities for members and their staff through national conferences and school-based training days. It has long been ackowledged that it is the responsibility of schools to identify, plan and seek to provide continuing development opportunities for teachers and IPD exists to support schools in discharging this responsibility.

IPD is based in Market Harborough and is under the direction of the joint Director of Professional Development, Dr Simon Letman. IPD's office is managed by the Professional Development Assistant (PDA), Sharon O'Flynn.
