Like the NCC, there is also a Police variant, for those more interested in Policing. Their purpose is the same as the NCC which is to equip various skills to the cadets and introduce them to the life in the Singapore Police Force. The Ministry of Education jointly administers the NPCC with the Singapore Police Force. For a time, the NPCC was administered as part of the NCC (known as the NCC Police), until the Ministry of Defence and the Interior split to become the Ministry of Defence and the Ministry of Home Affairs.

The NPCC Flag is halved horizontally navy blue and white. The canton is charged with the NPCC emblem. The NPCC emblem is the SPF emblem but the scroll of the latter is changed to a scroll inscribed with NPCC for the Corps. Additionally, the date 1959 appears beneath the scroll. The white half is inscribed with "National Police Cadet Corps" in blue, nearer to its base. The flag was adopted on 20th April 2002.
