Get to know each school
Commonwealth Secondary School
Commonwealth Secondary began in 1964 as Tanglin Integrated Vocational Secondary School. It became Tanglin Secondary in 1969 and Commonwealth Secondary in 1972, commemorating the previous year's Commonwealth heads-of-government meeting in Singapore. It moved through two Jurong East campuses before reaching West Coast Road in 2006. Autonomous status dates to 1995, followed by recognised environmental-education and design-and-innovation centres in 2008 and 2016. This history helps explain its current mix of practical making, environmental learning and performing arts.
The eco-stewardship curriculum describes Geography water-quality investigations in the stream and wetland, Science farm-to-table work, and hydroponic design in Craft and Technology. Campus spaces include a rainforest, marine aquarium, plant nursery and indoor and outdoor farms. These are concrete learning settings; the pages do not give a fixed fieldwork allocation for every cohort. CCA projects also link sustainability with community partners and causes such as responsible consumption or animal welfare. Parents can ask how often students use these spaces within ordinary lessons.
St. Joseph's Institution
SJI began as St John’s School in 1852, a free boys’ school on Bras Basah Road established by the De La Salle Brothers. It took the St Joseph’s Institution name in 1855. In 1988 it became independent and moved to Malcolm Road; after a temporary Bishan relocation for redevelopment, it returned in 2017. The dual secondary pathway and co-educational post-secondary IB Diploma began in 2013. SJI International, established separately in 2007, should not be confused with this institution when checking fees, admissions or reviews. Historical free schooling also does not describe today’s independent-school charges.
The current SEC Programme page describes a four-year route preparing boys for Secondary Education Certificate examinations, with seven- or eight-subject combinations at upper secondary. SJI’s IP is a six-year route leading to the IB Diploma. Both pages describe a lower-secondary foundation in languages, humanities, sciences and mathematics, with inquiry and research. At Years 3–4, SEC pupils have Curriculum+, including project work and career encounters; IP pupils have Year 3 ArtScience and Year 4 Signum Fidei projects with external organisations. Confirm which route an offer covers and its progression conditions, rather than assuming secondary entry guarantees any later course or subject choice.
