The Baltimore Polytechnic Institute, colloquially referred to as BPI, Poly, and The Institute, is a US public high school founded in 1883. Established as an all-male manual trade / vocational high school by the Baltimore City Council and the Baltimore City Public Schools, it is now a coeducational academic institution since 1974, that emphasizes sciences, technology, engineering, and mathematics ("STEM"). It is located on a 53-acre (21 ha) tract of land in North Baltimore on the east bank of the Jones Falls stream. B.P.I. and the adjacent still all-girls population of the Western High School are located on the same huge joint campus at the northwest corner of West Cold Spring Lane and Falls Road.
