The seminary was originally created to prepare candidates for Lutheran ministry in Western Canada.

LTS provides training for pastors and diaconal ministers; offers Lutheran formation for leaders and laypeople; and advances the study of rural ministry.

A merger occurred in 1965, joining the two organizations into the present Lutheran Theological Seminary Saskatoon, with a faculty of six and a student body of thirty.

When the ELCIC approved the diaconal ministry roster, the Seminary began to develop a program to address the academic needs of these students.

The seminary, in conjunction with the ELCIC's Candidate Committees and the national Program Committee for Leadership in Ministry (PCLM), helps coordinate the recruitment and discernment process for candidates for pastoral leadership.
