The name of the College, "Tampines" is prominently displayed on the crest. The two large stylised letters, JC, which are the initials for Junior College, form a triangle with a wide base and an apex.

The broad, strong base signifies the principle of focusing on the all-round develepment of the students, upon which the College is founded, while the apex reflects the College motto: "Aim and Achieve," by suggesting the upward thrust (Aim) of continuously working, in all areas of activity, to excel (Achieve).

Gold stands for that quality of excellence which is inherent in all attainments whilst the colour red reflects steadfastness in the determination of the students to achieve this excellence.
