Canadian International School, Singapore Reviews
We read Reddit, Facebook, and expat forums so you don't have to.
Canadian International School Singapore is one of the city-state's largest full-IB schools, and it attracts unusually mixed feedback in public sources.posts a parent rating of 3.1 out of 5 from 13 reviews, and its October 2025 visit write-up positions CIS as friendly and well-resourced, but not without recurring complaints in online discussion.
What parents and students praise
The strongest positives are about range and facilities.highlights bilingual pathways (Chinese-English and French-English), large-scale arts and sports facilities and an Outdoor Discovery Centre supporting hands-on learning. A 2025 review on Expat Exchange describes a warm administration and an international curriculum track through IB programmes.
Where criticism lands
The most pointed criticism is about culture and management rather than teaching. On Reddit, teacher comments describe CIS as profit-driven and raise concerns about behaviour management and workload. Reddit deep extraction was not available in this cron run, so these claims are treated cautiously and based on search-visible excerpts.
“Would definitely NOT recommend CIS to send your kids to. It's solely a profit driven school...”
Bottom line
CIS reads as a big, full-IB campus with genuine breadth and facilities, but with a more uneven reputation than some peers, including a middling parent rating on. Families who value bilingual tracks and scale may find it compelling; those who prioritise tight behaviour culture and a smaller community will want to probe day-to-day standards.
