NJC offers a two-year course for pre-university students and a six-year Integrated Programme, both leading to the Singapore-Cambridge GCE Advanced Level examinations.

[4] In 1967, construction began on the first institution that operated under this arrangement, which was named National Junior College.

[6] Unlike other pre-university schools of the time, students were given the freedom and flexibility to opt for their subjects under the college's lecture and tutorial system.

Besides General Paper, which was compulsory, other subjects offered to students included Art, Biology, Chemistry, Economics, English Literature, Geography, History and Mathematics.

[6] In keeping with its name and philosophy, the College claims no affiliation with any secondary school but instead draws its students from a wide spectrum.

NJC also plays host to German, PRC, Taiwanese, Vietnamese and Japanese students in exchange programmes.

[12] The uniform for male students is a shirt with shoulder epaulettes, secured by square silver buttons embossed with the school crest.

[14] National Junior College used this campus until 1997, when it shifted to its present location at Hillcrest Road.

[21] At the 2007 Ministry of Education Workplan Seminar, it was announced that five schools, including National Junior College, will each start their own boarding programme.

Thus, National Junior College's boarding school was constructed to cater to the new programme and it was officially opened on 16 May 2009.

Built at a cost of SGD $20 million, this boarding school has 250 rooms housing around 500 students and teachers.

[citation needed] In National Junior College, various special programmes are also offered in addition to the standard school curriculum.

These summits and conferences are jointly organised with the Ministry of Education, and is participated by more than 70 schools locally and internationally.

While in office, Student Councillors will be split into various committees that are in charge of the planning and execution of initiatives that fall under their respective roles.

[28] National Junior College has nurtured many notable alumni in various fields such as politics, civil service, business, academics, as well as entertainment.

This includes former Prime Minister of Singapore Lee Hsien Loong, opposition politician Chen Show Mao, and actress and director Claire Wong.
