St Joseph’s Institution International School

About Us

Established in 2007, St Joseph’s Institution International School offers a holistic, values-driven and international educational experience to a diverse student body of 40 nationalities rooted in the context of Singapore.

As a school with a Lasallian Catholic foundation, our community welcomes students, teachers, parents, friends and supporters of all faiths and cultural backgrounds. Our core Lasallian values are central to everything that we do: spirituality, mutual respect, internationalism, leadership, experiences and service. We strive to develop students who are intrinsically motivated to serve others and to give back to the community.

Today, we celebrate a community of 1,800 students across two schools on one campus. The High School admits both Singaporean and international students in Grades 7 – 12 (ages 12 – 18); while the Elementary School caters to expatriate children from pre-school Prep 1 – 2 (ages 4 turning 5 – 6) and Grade 1 – 6 (ages 7 – 12).



Nestling in the lush greenery of the Thomson suburbs, St Joseph’s Institution International School campus facilities for High School students include the Dr Stephen Riady Library; the IB Student Centre; spacious classrooms and learning spaces; 13 science laboratories; IT and music technology resources; a drama BlackBox space; The Lawrence da Silva Sports Complex featuring a 25-metre swimming pool and indoor sports hall, fitness room, and rock climbing wall; outdoor basketball, netball, and tennis courts; a brand new FIFA-approved artificial turf field; a Campus Ministry Centre and a chapel.

Suitable teaching and learning spaces are available for the specific needs of the Elementary School, including a specialist library for ages 4 – 12, purpose-built classrooms, gardens and playgrounds, art and music rooms, an ICT suite, a flexible indoor hall, and an outdoor sports court.
