Two spacious and multi-functional auditoriums serve as venues for various activities and events at the school. The school staff and students assemble in the main auditorium for the daily morning assembly and other functions. The students use the main auditorium for after-hours sports activities like badminton and table-tennis, and for movies and other entertainment programmes on specific days which help them unwind.
These halls also serve as the examination halls for the ICSE and ISC examinations since RiverDale has been recognized as a centre for conducting the final board examinations. The school’s main auditorium is one of the busiest locations of the school, constantly bustling with activity throughout the day.
