The NBCC had long felt the need of establishing a theological seminary in Nagaland. A milestone in the history of the NBCC was thus achieved with the founding of OTS in 1991. Under the ownership and sponsorship of the NBCC, OTS continues to aim for excellence as an institution and as a community of God.

The convictions behind OTS have been clear from its very birth.  On the practical side, OTS would fulfill the felt need of having a graduate level theological school in Nagaland. This would ease the growing demand of theological students seeking admissions for higher studies in other parts of India or abroad for lack of adequate institutions at home. OTS has the distinctions for being the first theological seminary to provide graduate studies in Nagaland.

A more serious conviction of establishing OTS, is the primary purpose of imparting dialogical theological education and upholding the uniqueness of Jesus Christ in the realm of theological studies. Such a focus we believe, will prepare men and women for relevant and adequate leadership in our churches and society.

The first academic session began in July 1993 with the first graduating class in 1996. Since then, our graduates as of 2016 consist of close to 400 men and women, placed in different ministries at home and abroad. We are proud of our alumni and their ministries as they live out their calling and commitment.
