Trine University is a private university in Angola, Indiana. It offers degrees in the arts and sciences, business, education, and engineering. Trine University is accredited by the Higher Learning Commission.
Trine was founded in 1884 as Tri-State Normal College and retained the reference to the "tri-state" area for more than 120 years because of its location in Indiana and proximity to Michigan and Ohio. In 1906, the school was renamed Tri-State College, and in 1975 Tri-State University.
The school served its regional population, first as a teachers and engineering school with flexible evening and weekend courses and then broadening into a multidisciplinary institution with an expansion of daytime classes, an athletics program and more robust student life offerings. On June 1, 1963, Tri-State succeeded in achieving its initial regional accreditation. It has remained an accredited institution since that time, most recently extending its Level V accreditation until the next (2026) evaluation visit. Further, the Ketner School of Business was reaffirmed by the Accreditation Council for Business Schools and Programs (ACBSP) on February 26, 2019.
