CTS offers education at certificate, diploma, bachelor’s and master’s levels. A distinctive feature of education at this seminary is that students can choose to follow courses in English, Sinhala, or Tamil up to undergraduate  level. At present, post graduate (MA) courses are offered in English only. 

CTS was formed with the intention of serving those who would continue in their place of ministry while studying, so education is offered as credit-based courses and classes are conducted in the evening and over weekends in addition to the regular weekday classes. This has enabled students to study at their own pace while continuing their involvement in ministry in the church and/or marketplace. Courses are designed with special focus on the relevance of theology to life in the twenty-first century. All CTS programmes are accredited by the Asia Theological Association (ATA).
