go beyond the realms of ordinary education. Houses The five houses, named after Albert Einstein, Leonardo da Vinci, Aristotle, Rabindranath Tagore, and Ernest Rutherford, are represented by the colours red, purple, blue and yellow respectively. Year 1 students are sorted into houses by class. The results from inter-house sports and academic competitions are summed up in a yearly points system. House allocations used to be student-based, instead of class-based. However, since 2020, there are no longer houses in TK. Uniform Boys wear white short-sleeved shirts with a school badge on the breast pocket. Lower Secondary boys wear white short trousers. Upper Secondary boys wear long white trousers. Girls wear a short-sleeved blouse with the school badge on the left. The skirt is jade-green with box pleats. A green and yellow striped tie is worn on some occasions. School Building A possible reason behind the incorporation of an octagonal structure in the school's building can be related to Leonardo da Vinci's obsession on octagons and the school's association with him. Student life Leadership Development Opportunities A select 15 PHL students will form the panel of the CCM Grant, a programme by the National Youth Council. As the CCM Panelists, they will be assessing community service project grant applications supported by their peers. Year 4 PHL students will attend an annual mass training on Effective Communication and Presentation Skills. Tanjong Katong Band The TK Band has its roots in the school bands of the former Tanjong Katong Technical School and Tanjong Katong Girls' School. The bands started separately in 1965 with only 26 members. In 1967, the two bands came together for a combined performance that marked their long relationship. The band split again in 1989, with TKGS going its own way. Since established, it has represented the republic in several overseas events and International Bands' festivals. In 1998, the band was invited to put up a solo performance in the National Day Parade (NDP), the first ever for any school band. It also appeared on National Day Parades 2002, 2004 (during the pre-parade segments in both years), NDP 2012, Chingay Parades, etc., in solo performances. In 2014, TK Band was invited to play at the Taoyuan Band Festival in Taiwan (Republic of China). TK Band was also invited to play at the Singapore Youth Festival Opening Ceremony 2014 held at Gardens by the Bay. After 2 years of no school performers
