Q: What does International Junior Informatics Olympiad (IJIO): 2025/26 Guide for Singapore Students cover?
A: What the IJIO is (Singapore context), who it is for, and a practical preparation plan for parents and students.
TL;DR
In Singapore, “IJIO” commonly refers to SIMCC’s International Junior Informatics Olympiad, which is open to Primary 1–6 students and emphasises computational thinking and block programming.
Dates, registration steps and the grade-level syllabus are maintained on the official IJIO page — treat third-party summaries as secondary.
Use IJIO as a low-stakes on-ramp: loops, conditionals, variables and problem decomposition transfer well to later text-based coding (and eventually contests like NOI).
Status: SIMCC IJIO page checked 2026-01-26 — eligibility listed as Primary 1–6 and the contest emphasises computational thinking + block programming.
If your family is planning a longer “computing runway” into secondary school, pair IJIO-style logic practice with strong Maths fundamentals (algebra, sequences, graphs) from our IP Maths hub.

1 What IJIO is (Singapore context)
- Organiser: Singapore International Math Contests Centre (SIMCC).
- Who it’s for: Primary 1–6 (see the official eligibility).
- What it trains: computational thinking and block programming, with an explicit goal of building foundations that can later transition to text-based coding.
2 What students practise (by grade band)
The official IJIO page publishes a grade-banded syllabus. At a high level:
- Primary 1–2: algorithms / step-by-step instructions, variables and basic conditionals.
- Primary 3–4: iteration (loops), coordinate grids, booleans and structured problem-solving.
- Primary 5–6: data representation themes (e.g., binary), arrays and more complex logic.
Treat these as themes, not a complete checklist — follow the official syllabus for the year your child is entering.
3 A simple 4-week prep plan (no burnout)
- Week 1 (setup + habits): 15–20 min/day of block-coding puzzles; practise writing a clear “plan” before coding.
- Week 2 (logic reps):
