ICAS (International Competitions and Assessments for Schools) is an Australian academic competition run by UNSW Global for students in Years 2–12. It assesses skills in English, maths, science, spelling, and writing across a range of year levels.

The number of questions varies by subject and year level. Most ICAS papers contain 30 to 50 multiple-choice questions completed within a 40–60 minute time limit, with some subjects including short-answer or written response sections.

ICAS results are reported on a scale from Distinction to High Distinction, with the top 1% receiving a High Distinction medal. A credit or above (typically scoring in the top 25%) is considered a strong result for the competition.

ICAS is open to school students in Australia and internationally in Years 2–12 (or equivalent). Students participate through their school, which registers for the competition on their behalf each year.

ICAS covers five main subject areas: English (reading and language), Mathematics, Science, Spelling, and Writing. Students can enter one or more subjects, and papers are tailored to each year level.

The best preparation involves completing past ICAS papers under timed conditions, reviewing the syllabus topics for your year level, and practising weak areas — especially in maths problem-solving and English comprehension. Consistent practice over several weeks is more effective than last-minute cramming.
