Students from the Raffles Programme remained in the same House for the entire six years, while students enrolled into RJC via the Joint Admissions Exercise (JAE) were assigned to a House upon admission. Houses compete in Inter-House Competitions (IHC) annually. Organised by the Students' Council, the events span across disciplines and challenge participants both physically and mentally. The IHC Remix is generally held earlier in the year and comprises the non-Sports events whilst IHC Sports is held later in the year.
