SSS started as Serangoon English School in 1928, housed in a two-storey building in Simon Road.

In 1937, the school added three standards, providing education up to Secondary Three in present-day terms.

In 2001, SSS moved to its present premises at 11 Upper Serangoon View.

All of its uniformed groups have attained the gold award for the Best Unit every year from 2008 onwards.
