Science, technology, engineering, and mathematics (STEM) is a broad term used to group together these academic disciplines. This term is typically used to address an education policy or curriculum choices in schools. It has implications for workforce development, national security concerns and immigration policy. The science in STEM typically refers to two out of the three major branches of science: natural sciences, including biology, physics, and chemistry; and formal sciences, of which mathematics is an example, along with logic and statistics. The third major branch of science, social science such as: psychology, sociology, and political science, are categorized separately from the other two branches of science, and are instead grouped together with humanities and arts to form another counterpart acronym named HASS (Humanities, Arts, and Social Sciences), rebranded in the UK in 2020 as SHAPE.The acronym was adopted by Rita Colwell and other science administrators in the National Science Foundation (NSF) in 2001. However, the acronym STEM predates NSF and was used by a variety of educators including Charles E. Vela, the founder and director of the Center for the Advancement of Hispanics in Science and Engineering Education (CAHSEE). In the early 1990s, CAHSEE started a summer program for talented under-represented students in the Washington, DC area called the STEM Institute. Based on the program's recognized success and his expertise in STEM education, Charles Vela was asked to serve on numerous NSF and Congressional panels in science, mathematics and engineering education; it is through this manner that NSF was first introduced to the acronym STEM. One of the first NSF projects to use the acronym was STEMTEC, the Science, Technology, Engineering and Math Teacher Education Collaborative at the University of Massachusetts Amherst, which was founded in 1998.
