ICAS Maths practice

ICAS Mathematics is a school-based maths assessment that many Australian students sit each August, from Year 2 right through to Year 12. Each year level has its own paper, labelled from Intro to J, and the questions climb in difficulty through the paper so that strong students are stretched rather than simply finishing early. This page sets out which paper each year sits, how many questions and how long, the learning areas the papers cover, and how students enter, all from ICAS Assessments' own pages. It then works through one topic the senior papers name, turning recurring decimals into fractions, because it is the kind of question that rewards understanding over speed.

In short

ICAS Mathematics is a maths assessment run by ICAS Assessments for Australian students from Year 2 to Year 12. Year 2 sits the Intro paper of 30 questions in 35 minutes; Years 3 to 12 sit Papers A to J, each with 40 questions, in 45 minutes for Papers A to C and 1 hour from Paper D. In 2026 the Mathematics sitting window was 24 to 28 August.

For ICAS Mathematics

Three courses that match the ICAS papers

One for the primary papers, one for the middle years, one for the senior papers.

ICAS Mathematics papers by Australian year level

ICAS Assessments publishes the paper for each year and the length of each one. These figures are theirs, read on 7 October 2026.

EYear 7401 hour
FYear 8401 hour
GYear 9401 hour
HYear 10401 hour
IYear 11401 hour
JYear 12401 hour

The jump that catches families out is between Paper C and Paper D. Year 6 keeps 40 questions but gains a quarter of an hour, and the content steps up with it. From Paper D upwards, every paper is 40 questions in 1 hour, so a steady pace of about one question every minute and a half is the planning figure.

ICAS Assessments notes that international schools registered with it "should sit the papers according to the Australian year levels", which is why the Australian column is the reference point.

ICAS describes the questions as increasing "in complexity throughout the paper". That changes how to practise: early questions should become quick and reliable, so that time is left for the harder ones at the end, rather than racing to finish.

The school, testing centre or partner running the assessment sets up how and where students sit it. Ask them what to expect on the day, so the format is not a surprise.

What is tested

Five learning areas, rising paper by paper

ICAS Assessments lists the learning areas and gives examples for each paper. The examples below are quoted from its Mathematics page.

The learning areas

ICAS lists Number and Arithmetic, Algebra and Patterns, Measures and Units, Space and Geometry, and Chance and Data.

The aim

ICAS says its Mathematics assessments are "designed to provide an objective ranking of students' performance based on the curricula for the relevant year".

The style

Questions test "logical reasoning, problem solving and critical thinking", in ICAS's words, rather than recall alone.

Examples ICAS Assessments gives for selected papers, quoted
PaperYearStudents may be asked to
AYear 3"order and compare halves, quarters and eighths, multiply and divide by single digits using different techniques"
DYear 6"complete number sentences involving all four equations, solve problems involving parallel and perpendicular lines, or interpret and compare column graphs, dot plots and tables"
E and FYears 7 and 8"solve percentage and ratio problems, interpret authentic graphs to solve linear equations, solve problems using angle sum of triangles and quadrilaterals, or calculate mean, median, mode and range"
G and HYears 9 and 10"convert terminating and recurring decimals to fractions, factorise linear expressions, solve linear equations graphically and algebraically"
I and JYears 11 and 12"apply index laws involving integer and fractional indices, solve financial problems using simple and compound interest"

Taking part

How students enter ICAS Mathematics

ICAS Assessments describes three routes into the assessment. We are not one of them; we teach maths.

Entry routes and 2026 dates, from ICAS Assessments
Route or dateWhat ICAS Assessments says
Through schoolSchools register and choose the year levels and subjects; parents are invited to enter; students sit the test at school
Testing centreIf a school does not offer ICAS, students can sit at an ICAS testing centre hosted at Cliftons locations across Australia
Authorised partnerAn approved provider that coordinates the competition locally
Parent Payment SystemLets parents register and pay for their children's entries through the school
2026 Mathematics window24 to 28 August
2026 entry deadlineSchool entries closed Friday 24 July; for Mathematics the date was extended to Sunday 16 August, 11:59pm AEST

For most families the school route is the only one that matters: if the school runs ICAS, entry comes through a letter or the school's portal. Entry fees are in Australian dollars and are set by ICAS Assessments, so we do not reproduce them.

ICAS Assessments also sells past papers through its own shop. We link to the publisher rather than copying any of its questions.

Results and certificates, according to ICAS Assessments, are provided through the school and can also be viewed online. The organisers publish their own guidance on understanding results.

Dates for 2027 were not published when we checked. The August pattern in 2026 is a reasonable guide, and the school will confirm.

A worked topic from Papers G and H

Turning recurring decimals into fractions

ICAS Assessments names "convert terminating and recurring decimals to fractions" among the skills for Papers G and H. The Australian Curriculum introduces the idea in Year 8 (AC9M8N03, "recognise terminating and recurring decimals"). Here is the method, with three examples we checked exactly.

Three recurring decimals converted to fractions (our examples, checked with exact fractions in Python)
DecimalMethodFraction
0.272727... (27 repeating)Let x be the decimal. 100x is 27.2727..., so 100x minus x is 27, and 99x is 2727 over 99, which simplifies to 3/11
0.1666... (6 repeating)10x is 1.666... and 100x is 16.666..., so 100x minus 10x is 15, and 90x is 1515 over 90, which is 1/6
2.3454545... (45 repeating)1000x is 2345.4545... and 10x is 23.4545..., so 990x is 23222322 over 990, which simplifies to 129 over 55

The idea is to multiply by a power of ten that lines the repeating part up with itself, then subtract so the endless tail cancels. The number of repeating digits decides the power: two repeating digits means multiplying by 100, one means 10.

The third example is the one students get wrong. When some digits do not repeat, you need two multipliers, one to move past the non-repeating part and one to line up the repeat. 1000x and 10x give 990x, and only then does the fraction appear.

There is a quick check in multiple-choice conditions. A fraction in simplest form has a terminating decimal only if its denominator has no prime factors other than 2 and 5. So 3/11 and 1/6 must recur, while 1/8 must terminate. Of the unit fractions from 1/2 to 1/12, only 1/2, 1/4, 1/5, 1/8 and 1/10 terminate.

Knowing why the method works makes ICAS questions on this topic quick, and it carries straight into senior maths, where the same subtraction trick appears in geometric series.

Preparing well

Four habits for ICAS Mathematics

Good preparation builds mathematics, not test tricks. These habits help on any paper.

Preparation habits for ICAS Mathematics
HabitWhy it helpsThe sign it is secure
Secure the early questionsQuestions rise in difficulty through the paperThe first third of a practice paper is done calmly and correctly
Read the whole questionReasoning questions hide the key detailUnderlines what is asked before calculating
Estimate before choosingMany wrong options are far from the right sizeRules out impossible options with a quick estimate
Check the answer fitsA right method can still give a slipped answerSubstitutes the answer back or compares it with the estimate

If your child finds ICAS stressful

ICAS is designed to stretch strong students, so finding later questions hard is normal, not a warning sign.

Treat it as a challenge and a source of feedback, not a judgement.

Questions about ICAS Mathematics

What Australian families ask

What is ICAS Mathematics?

A maths assessment run by ICAS Assessments for students from Year 2 to Year 12 in Australia. Each year level sits its own paper, and questions grow harder through the paper.

Which ICAS Maths paper will my child sit?

Year 2 sits the Intro paper, Year 3 Paper A, and so on up to Year 12, which sits Paper J.

How many questions are in ICAS Maths, and how long is it?

The Intro paper has 30 questions in 35 minutes. Papers A to J have 40 questions: 45 minutes for Papers A to C and 1 hour from Paper D (Year 6) upwards.

When is ICAS Maths held?

In 2026 the Mathematics sitting window was 24 to 28 August. Check with the school or ICAS Assessments for the next year.

How do students enter ICAS?

Usually through their school. ICAS Assessments also describes testing centres hosted at Cliftons locations and authorised partners. We are not an entry provider.

What areas does ICAS Maths cover?

Number and Arithmetic, Algebra and Patterns, Measures and Units, Space and Geometry, and Chance and Data.

How do you turn a recurring decimal into a fraction?

Call the decimal x, multiply by a power of ten that lines up the repeating digits, and subtract so the repeating tail cancels. For 0.2727..., 100x minus x is 27, so x is 27 over 99, which is 3/11.

Where can students find practice papers?

ICAS Assessments sells past papers through its own shop. Our classes teach the mathematics with our own examples.

Will your classes raise my child's ICAS result?

We do not promise any result or award. We teach the mathematics the papers draw on, with reasoning and checking built in.

Are you connected with ICAS Assessments?

No. We are an independent online school, quoting ICAS Assessments because it runs the assessment.
