The Sunday School is the church’s way of reaching out to our youngest members to help mould them into good human beings who live with Christian values. It plays a major role shaping their character and enabling them to grow into  responsible members of the society.

Mar Aprem Sunday school teaches students from Grade 1 through Grade 10. Examinations are conducted twice a year to test the students, and the annual cultural fest (Kuruvilachan Trophy) is held to bring out and nourish their talents that help the ministry.

The history of Mar Aprem Sunday School can be traced back to the year 1905, when Rev. Fr. Padavupurakkal Thomas alias Kuruvilachan initiated the Gospel Children Shining Light Sunday School to instil in children the faith of the Apostolic Church faith. In 1914, the school was renamed to Bethany Sunday School, and it was rechristened to its present name – Mar Aprem Sunday School in 1920.

The school’s initial syllabuswas designed and developed by late Mar Abimelek Timotheus Metropolitan in 1914. Over the course of years, the syllabus was renewed and modified, and it includes bible study, church history, Patrology and the Syriac language.
