The emblem is of an open book signifying a progressive and outward-looking approach in our attitude as well as in business, especially our corporate regional plans. It also depicts our spirit of constant learning, regardless of age or station in life.

Seen from one end of the spine of the book, the word STET leaps out of the pages as the book is opened. It marks the focus of STET in education and training, and its commitment to life-long learning.

The colors of the STET logo were chosen to represent the three services of the Singapore Armed Forces - dark blue for the Navy, light blue for the Air Force, and red for the Army.

The letters 'ST' denote our establishment under the Singapore Technologies umbrella and are retained to leverage upon its "brand name" ; they follow their traditional black color. The letters 'ET' are in dark blue as a tribute to our heritage from our founders in the Republic of Singapore Navy.
