The Engineering, Science, and Management War Training program (ESMWT) was one of the largest and most productive educational activities in America's history. It was perhaps only second to the G.I. Bill (officially the Servicemen's Readjustment Act of 1944) in its scope and productivity.

Sometimes referred to as an "experiment in streamlined higher education", this government-sponsored program provided, without charge, college-grade courses for large numbers of Americans to fill urgently needed technical and scientific civilian positions just prior to and during World War II. College-grade was officially defined as "work of an academic standard customarily demanded of engineering-school students."

With successive designations of Engineering Defense Training (EDT), Engineering, Science, and Management Defense Training (ESMDT), and ESMWT, the program was operated by the U.S. Office of Education from October 1940 through June 1945, with 227 colleges and universities providing about 68,000 courses for close to 1,800,000 students at a total cost of some $60 million ($940 million today's dollars).
