Diplo and the Global Health Programme (GHP) of the Graduate Institute of International and Development Studies signed an agreement, in May 2012, to develop and run an online course on Global Health Diplomacy. Course materials were developed in May and June 2012, with the GHP drafting the modules and DiploFoundation advising on course design, didactics, and learning activities. The pilot course started in June 2012 for a small initial group of 12 WHO Heads of Country Offices.
