The change was, in part, instigated at an interagency meeting by Peter Faletra the director from the Office of Science division of Workforce Development for Teachers and Scientists. 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 Vela, the founder and director of the Center for the Advancement of Hispanics in Science and Engineering Education (CAHSEE).[4][5][6] In the early 1990s, CAHSEE started a summer program for talented under-represented students in the Washington, DC area called the STEM Institute.
