The Sunday School at ICF focuses on two areas for its curriculum: Islamic and Quranic studies.

Each school day is divided into two sessions, one each for Quranic and Islamic studies. Within each session, teachers focus on introducing a new concept and then encourage students to share their thoughts, opinions, and engage in inquiry-based dialogue. The sessions aim to promote learning through class-wide interaction where the instructor serves as a planner, host, moderator, and fellow-student.

The curriculum is further enhanced with the planning, preparation, and execution of an end of year event where students participate in art and essay competitions and class presentations.
