The school's mission is to provide educational opportunities for students from Mother Science College seeking help, in order to develop skills enabling them to lead productive lives.
History
This school opened on 15 February 1954. The original staff consisted of Wimala Silva and S. Manual Pillai, with S. Rathnasabapathy as the principal. The first half decade of Science College reflects Rathnasabapathy's personality and dedication. His philosophy was to advance the college's educational and environmental conditions. Although large schools operated in Matale district when Science College was founded, no facility was dedicated to promoting higher education in science. V. T. Nanayakkara, the member for the Matale electorate, set out to correct this deficiency. The result was GSC. The school accepted students from districts beyond Matale such as Kandy, Kurunegala, Anuradhapura, Pollonnaruwa, Kegalle, Badulla, as well as the most remote district on the island, Jaffna. The students who studied there included Sinhalese, Tamil, Muslim and Burgher. In 1954, the school consisted of 40 students and two staff members but doubled in size that year. In the 1970s, enrollment increased to 250, and later exceeded 500. During those first decades, the focus was to promote as many students as possible to university level. In the 1960s, government policy of teaching science in both Sinhala and Tamil forced Rathnasabapathy to transfer to Jaffna. This became a turning point. Second principal H. R. P. Rupasinghe introduced cricket. Students proved successful in sports as well as academics, playing at a high level in cricket, field hockey and netball. In the 1980s, the department of education made the decision to end O/L classes, accommodating only advanced classes. This increased the number of students able to participate in higher education. The college developed a "Past Pupils Association", with branches in Colombo, Anuradapura, as well as in Australia. They assist the college in both its academic and sports endeavors.
Houses
Students are divided into three houses, named "Einstein", "Lavoisier" and "Darwin".
School song
The school song was composed by Mr. Thillekeratne, a teacher at GSC during the late 1970s, after an unsuccessful attempt to get a renowned songwriter in Sri Lanka to write one.
