How To Choose Australian Maths, Science And Coding Competitions For Your Child
Australian students have many competition options. That is good, but it can also be confusing. Parents often ask whether their child should do AMC, AIMO, ICAS, Big Science, Junior Science Olympiad, Australian Science Olympiads or AIO.
The best choice depends on three things: subject interest, current readiness and the purpose of entering.
Start With The Purpose
Choose a competition for one clear reason:
- diagnostic: to understand current strengths and gaps;
- motivation: to give the student a meaningful goal;
- extension: to go beyond school curriculum;
- pathway: to prepare for higher-level competitions;
- confidence: to practise exam conditions without high stakes.
Different competitions serve different purposes.
Maths Pathway
Start with the Australian Mathematics Competition if the student is new to maths competitions or wants a broad benchmark.
Move toward AIMO if the student already performs strongly in AMC-style problems and enjoys deeper proof-like reasoning.

Science Pathway
Start with Big Science or ICAS Science if the student needs a broad science benchmark. Move into Junior Science Olympiad when the student is ready for deeper integrated reasoning.
Students aiming for Australian Science Olympiads should gradually build subject depth in biology, chemistry, physics or Earth and environmental science.

Coding Pathway
Students interested in coding can begin with computational thinking competitions and move toward AIO when they can code complete solutions.

Do Not Overload The Calendar
Doing too many competitions can reduce preparation quality. For most students, one main competition and one supporting competition per term is enough.
Example combinations:
- AMC plus ICAS Mathematics;
- Big Science plus JSO;
- CAT plus AIO readiness work;
- AMC plus AIMO for strong maths students.
Use the Exam Calendar to map dates, and the exam guide index to compare formats before deciding.
FAQ
Which Australian competition should my child do first?
For maths, AMC is usually the best first competition. For science, Big Science or ICAS Science can be a good first benchmark. For coding, begin with computational thinking before AIO.
Should my child do many competitions in one year?
Only if preparation quality stays high. Too many competitions can create stress and shallow practice.
Which competition is best for extension students?
AIMO, Junior Science Olympiad, Australian Science Olympiads and AIO are stronger extension pathways. AMC, ICAS and Big Science are broader entry points.
Where should parents check dates?
Use the AceAchievers Exam Calendar for a parent-friendly view, then confirm final details with the official organiser or school.
