Foundation years Pioneer Junior College was established on 2 January 2000, with the inaugural principal, Mr. Kwek Hiok Chuang making the news as Singapore's youngest appointed principal in recent years. The college initially was located at the former campus of the French-German Institute of Singapore, along Science Centre Road. The college relocated to the current permanent campus at 21 Teck Whye Walk in December 2004. It was officially declared open by Mr.
Tharman Shanmugaratnam, then acting Minister of Education on 20 February 2004. Sixty-two teachers and executive and administrative staff, and two hundred students, were the first batch of Pioneers of Pioneer Junior College (the "Pioneer Pioneers"). Students were involved in the formation of the college rules and the design of the college crest and uniform. The college's vision and mission statements were formally endorsed on 31 August 2000 by the College Advisory Committee, students' parents, the staff and students. In the subsequent year, on 8 August 2001, the college anthem and flag were formally adopted by the college community. On 25 February 2002, PJC became the first junior college to launch its own satellite ground receiving station. Its inaugural College Day was held on 26 April 2002 to award deserving pioneers who had contributed in one way or another to the college. The guest-of-honour was the Chairman of the College Advisory Committee, Professor Phua Kok Khoo.
Integration of Jurong Junior College On 20 April 2017, it was announced that
Jurong Junior College will be integrated into Pioneer Junior College with effect from January 2019, with the new name as
Jurong Pioneer Junior College, which is a combination of the two schools' names. JJC's current principal, Dr Hang Kim Hoo, will take over as the principal of Jurong Pioneer Junior College. This was in view of the declining enrollment into junior colleges since 2014, attributed to the fall in Singapore's birth rate. The merger process is to be completed by January 2019. == Principals ==
