In 2004 the school was accorded Autonomous status. Following the new status came the School Distinction Award; the school was one of the pioneer 12 schools to be given the award. Another addition that year was the presentation of Singapore Quality Class status in recognition of the efficient organisation of the school. The academic curriculum in the school was recognised when it received the Best Practice Award for Teaching and Learning. Other areas were recognised with the achievements of Sustained Achievement Awards for Physical Fitness, Uniformed Groups and Value-Added. As a result, Tanjong Katong Secondary School is prominently known throughout the country for its excellent curriculum.
