| School Song |
| Lyrics by Mrs Lee Hong Leong and Miss Ho Swee Yin |
| Music by Mr John De Souza |
| We are one big family In Clementi Town Secondary With a true spirit and with zeal Diligence and loyalty Together we grow in wisdom, strength and unity |
| CHORUS Clementi Town Secondary We pledge to uphold your name From each his best and yet as one We'll strive to aspire and grow (Repeat) |
| In all endeavours we’ll work hard In lessons or sports or in music Skills and good traits to be acquired Not forgetting humility For country and nation – We'll serve in peace and harmony |
