About this exam

ICAS Science is an annual science competition for school students, run by ICAS Assessments (powered by Janison) and open to students from Year 2 to Year 12. It is a challenge-style competition rather than a syllabus test: students answer questions built around real scientific stimulus materials and are ranked against their peers, with results reported against curricula for the relevant year. Papers are mapped to year levels - an Introductory paper for students in the equivalent of Year 2, then Papers A through J across Years 3 to 12 - and are graded to stretch a wide range of abilities, including gifted and talented students. The question writers are expert educators who review the papers each year, and the skills assessed are observing and measuring, interpreting, predicting and concluding, investigating, and reasoning and problem solving. Recognition is built in: certificates for all participants and medals for the highest achievers, with achievement levels that are clearly defined and consistently applied. Preparation is straightforward: past papers are promoted as the most effective way to practise genuine ICAS questions and become familiar with the question style. Entries for 2026 have closed, and the official site invites families and schools to register interest for 2027 updates. Confirm dates, fees and paper details with ICAS Assessments directly, as these vary and are not published on the pages summarised here.

What you'll study

Common questions

About ICAS Science preparation

Which year levels can enter ICAS Science?

The competition runs from Year 2 to Year 12. Papers are tied to year levels: an Introductory paper for students in the equivalent of Year 2, then Papers A to J across Years 3 to 12, so a Year 6 student sits Paper D and a Year 11 student sits Paper I.

What kind of questions appear on the paper?

Questions are built on real scientific stimulus materials and test five skill areas: observing and measuring, interpreting, predicting and concluding, investigating, and reasoning and problem solving. Younger papers cover ideas such as shadows, seasons and life cycles; senior papers move into areas like accuracy versus precision and experimental ethics.

How long is the test and how many questions are there?

These details are not published in the official material summarised here, so treat any figure you see elsewhere with caution. Check the ICAS Assessments site or your school's competition coordinator for the current paper length, question count and sitting arrangements before you plan practice timing.

How hard is ICAS Science?

It is designed to be fun but challenging, and papers are carefully graded to stimulate interest across a wide range of abilities, including gifted and talented students. It is not a pass/fail test; it gives an objective ranking of performance against peers on the relevant year-level curriculum.

Can my child sit the test more than once if they are unhappy with the result?

No retake policy is published in the official source, and the competition runs as an annual event with entries closing for the year. If a result is disappointing, the practical route is to review the skill-area breakdown in the results report and prepare for the following year's sitting.

What is the best way to prepare?

Past papers are promoted as the most effective preparation, because they use genuine ICAS questions from previous years and make the question style and problem-solving approach familiar. Beyond that, practise reading data carefully - graph axes, tables, units - and answering strictly from the stimulus provided rather than from memory.

What do participants receive?

Every participant receives a certificate, and medals go to the highest achievers. Achievement levels are clearly defined, consistently applied and nationally standardised, and results show how a student performed in each skill area rather than only an overall score, which helps identify strengths and gaps.

How do I enter, and when is the next sitting?

Entries for 2026 have closed, and the official site invites you to register for updates about 2027. Dates, entry fees and testing arrangements are handled through schools and ICAS Assessments directly; they are not fixed in the material summarised here, so confirm them with the organiser.

Where do candidates most often lose marks?

Typical losses come from answering from general knowledge instead of the stimulus, misreading axes, units or table headings, and stopping at the first plausible option without checking the others. For investigate-style items, check which variable was changed, which was measured and which was held constant before choosing.
