A: What the IJIO is, why lower-secondary IP students should attempt it, how it feeds into the National Olympiad in Informatics pathway.
TL;DR
IJIO is Singapore's two-hour, four-problem programming contest for Sec 1-2 (IP Y1-2) students. Run by the National Olympiad in Informatics (NOI) committee at NUS School of Computing, it has recently been held in the September window; the 2025/26 dates will be confirmed via the official NOI SG site. Top performers may be invited directly to NOI Round 1 based on the rules for that cycle. Even if your child focuses on Maths or Physics, IJIO prep sharpens algebraic thinking, vector logic and experimental-design skills that reappear in IP weighted assessments.
Need a weekly structure that balances IJIO drills with algebra/physics revision? Borrow the practice sequences inside our IP Maths hub so contest prep reinforces what teachers test in weighted assessments.
Registration quick answer (Singapore): Registration opens on the NOI Singapore site; schools may coordinate entries but eligible students can follow the official instructions directly. Dates and rules change each cycle - see https://noisg.comp.nus.edu.sg/ for current details.
