As a form of outreach within the physics education community for teachers and students, in 1997 the US National Science Foundation (NSF) and Department of Energy USDOE established QuarkNet, a professional teacher development program. In 2012, the University of Notre Dame received a $6.1M, five-year grant to support a nationwide expansion of the Quarknet program. Also in 1997, the European Particle Physics Outreach Group, led by Christopher Llewellyn Smith, FRS, and Director General of CERN, was formed to create a community of scientists, science educators, and communication specialists in science education and public outreach for particle physics. This group became the International Particle Physics Outreach Group (IPPOG) in 2011 after the start up of the LHC.
