The S. Thomas’ Preparatory School Old Boys’ Union is delighted to highlight a wonderful initiative by the Prep Batch of ’98. 💙

The Prep Batch of 1998 generously donated funds to S. Thomas’ Preparatory School towards the purchase of three Smart Boards, funded entirely from the proceeds of Night of Rhythm 2025. The cheque was officially handed over to the Headmaster on 26th January 2026.

The Batch of ’98 has consistently been among the most active and engaged batches, continuously contributing their time, effort, and resources in support of the School. We congratulate the Batch on this meaningful contribution and thank everyone who supported this effort.

We hope this inspiring initiative will encourage other Prep batches to come forward with similar projects, as collective effort plays a vital role in strengthening and uplifting our beloved school.

The OBU looks forward to working closely with the Batch on future initiatives as we continue to support and uplift Prep together.

Once a Prepite, always a Prepite. 💙🤍💙

S. Thomas' Preparatory School
Old Boys' Union
The S. Thomas’ Preparatory School Old Boys’ Union (OBU), an association comprising of past prepites, was formed on May 12th 1978, coinciding with the commemoration of the 40th Anniversary of the school. Its aim and purpose are to assist and aid the school when called upon to do so, with the collective assistance of its old boys, and to instill a sense of brotherhood and camaraderie amongst the students who have had the privilege of studying there, and since left.
