Mount Calvary School was founded in 1980. It is an answer to the prayers of our brother and sisters in Christ. Since its commencement, Mount Calvary has faced varying degrees of hardships and adversities, but our trust in the living God never wavered. We have witnessed the hand of God, lovingly nurtured the school to its full potential and can still feel his continuous care for its growth. Now Mount Calvary School has almost reached the pinnacle of its glory with a very good reputation in the field of Education in Karbi Anglong. 

Mount Calvary School are the outcome of the foresight and vision of Rev. Dr. Timothy Rongphar, the founder and Principal of the school. He was the Director of Calvary Ministries committed not only to the cause of secular education but to a deep concern and conviction of eternal value of human life. 

Mount Calvary School is recognized by the Secondary Board of Education, Assam (SEBA).
