Quick Answer

Families most often ask which year levels can sit HAST, whether it is paper-based or computer-based, how scores are referenced to a high-ability cohort, who handles registration, whether one sitting covers multiple schools, and when results arrive. This page answers the ten we field most frequently and pairs with the HAST exam preparation hub for the wider context.

The questions below are the ten HAST questions our faculty at Braintree Coaching Australia fields most often from families preparing for the Higher Ability Selection Test. They sit alongside, rather than duplicate, the broader exam-overview answers on our HAST exam preparation hub — read the hub first if a fundamentals question (what HAST is, which schools use it, how to build a study plan) is still open, then come back here for the deeper, practical questions that follow.

HAST level Year of entry Components
Primary (HAST-P) Year 5, Year 6 Reading Comprehension, Mathematical Reasoning, Abstract Reasoning, Written Expression
Junior (Secondary) Year 7 Reading Comprehension, Mathematical & Scientific Reasoning, Abstract Reasoning, Written Expression
Middle (Secondary) Year 9 Reading Comprehension, Mathematical & Scientific Reasoning, Abstract Reasoning, Written Expression
Senior (Secondary) Year 11 Reading Comprehension, Mathematical & Scientific Reasoning, Abstract Reasoning, Written Expression

How does this FAQ pair with the rest of the HAST spokes?

The FAQ block below covers year-level eligibility, the paper-based format, high-ability scoring, the four components, school-by-school registration, sitting at multiple schools, results timing, special provisions, and how HAST differs from NAPLAN and other ACER tests. For the section-by-section walkthrough of every HAST paper — timing, question counts and what each component asks of your child — see our HAST test format guide spoke. For how raw scores, standardised scores, percentiles and stanines work once results arrive, see our HAST test results interpretation spoke, and for practice material to build the habit, see our HAST practice tests and resources spoke. The Higher Ability Selection Test is built, marked and reported by the Australian Council for Educational Research (ACER); registration, fees and test dates are set by each participating school, so confirm the specifics with the school your child is applying to.

What does a HAST family say after preparing with us?

These ten questions are the ones our faculty hears most; here is one family's answer to the question behind all of them — does the preparation actually help. Muditha K. was searching for HAST support that was neither too generic nor too advanced for her daughter, and found Braintree's course "clear, focused, and truly designed for this tough exam." The mock tests, in her account, especially in Abstract and Mathematical Reasoning, built her daughter's confidence and speed under timed conditions. As she put it: "we finally felt like we were on the right path" — quoted with consent. Read her full HAST preparation story.

FAQ

Common questions, plainly answered.

10 questions our faculty fields most often about this exam.

HAST is available to students from Year 5 to Year 12, with the level matched to the entry point. Primary HAST (HAST-P) is used for Year 5 and Year 6 entry. Secondary HAST is split into three levels — Junior (for Year 7 entry), Middle (for Year 9 entry) and Senior (for Year 11 entry). Each level is written for the cognitive development and academic complexity appropriate to the target age group, so a Year 7 candidate and a Year 11 candidate sit different papers. The school you are applying to determines which level and which year of entry applies.

HAST is a paper-based test, not computer-based. Candidates complete the multiple-choice sections with pencil and the Written Expression task with pen. This differs from assessments such as the NSW Selective High Schools Test and the Opportunity Class (OC) Test, which moved to a computer-based format. The practical implication for preparation is that your child should practise on paper — reading passages from print, working mathematics by hand, and writing extended responses with a pen under timed conditions — rather than relying solely on screen-based practice.

HAST results are reported as raw scores, standardised scores, percentiles and stanines, all referenced to a high-ability cohort rather than the general student population. This matters because the comparison group is already academically strong, so percentiles read lower than they would on a general test — a child at the 50th percentile on HAST has performed better than half of an already high-ability group, not half of all students. Each component (Reading Comprehension, Mathematical Reasoning, Abstract Reasoning and Written Expression) is reported separately, and the school decides how the components combine and which thresholds matter for its programme.

HAST has four components: Reading Comprehension, Mathematical Reasoning, Abstract Reasoning and Written Expression. Reading Comprehension assesses analysis of fiction, non-fiction and visual material such as diagrams, tables and charts. Mathematical Reasoning tests problem-solving with number, pattern and logic, and at Secondary levels can include applied science content. Abstract Reasoning measures pattern recognition and logical thinking independent of language. Written Expression is an open response judged on quality of thought, language and organisation. Some schools use a four-component package and others a three-component package, so confirm the exact set with your target school.

HAST registration is handled directly by each participating school, not by a central testing authority. There is no single national HAST sign-up; instead you apply through the admissions office of the school your child is targeting, which sets its own application form, deadline, fee and test date. Registration timelines are not standardised and can open many months ahead of the sitting, so the practical step is to contact each target school early — often in the term before applications open — to confirm dates and secure a place, as some schools have limited testing capacity.

Yes. Because each school administers its own HAST independently, a child can register for and sit the test at more than one school. Most families apply to two to four schools across a range of competitiveness. The trade-offs to weigh are logistical: separate registration fees apply for each school, test dates may fall close together or clash, and preparing for several sittings in a short window can add pressure. A HAST result sat at one school is generally not transferable to another, so each application normally requires its own sitting.

HAST results are returned to the school within 10 working days of ACER receiving the completed test papers — that is ACER's own stated turnaround for marking and reporting, not the date a family hears back. Once ACER has reported the results, each school decides how and when it tells families, by post, email, a parent portal or a scheduled debrief, so the practical wait for a parent depends on the school's own process rather than on ACER's marking time. Confirm the exact result-release date with the school, because the communication step sits with the school rather than with ACER.

Yes. HAST offers special provisions for students with a documented disability or learning difficulty, arranged through the school at the time of registration. Adjustments can include extra time, rest breaks, a separate testing room, reader or scribe support, alternative-format materials such as large print, and assistive technology where appropriate. To request provisions, apply early and supply supporting documentation — for example a medical report, an educational psychologist assessment, or a current learning support plan. The school determines the specific adjustments, so contact its admissions office well before the sitting.

HAST and NAPLAN serve different purposes. NAPLAN is a national assessment of literacy and numeracy against expected standards for all students at set year levels. HAST is a cognitive ability test built to identify high-ability students for selective and scholarship entry, and it includes an Abstract Reasoning component and an open Written Expression task that have no direct NAPLAN equivalent. Because HAST is referenced to a high-ability cohort and rewards reasoning rather than curriculum recall, a strong NAPLAN result does not by itself predict a strong HAST result, and the two require different preparation.

ACER is the organisation that develops HAST, so HAST is one of several ACER assessments rather than a competitor to ACER. ACER also produces general scholarship tests and other educational assessments, which is why a school may refer simply to an "ACER test" — always confirm which specific test is required. Compared with curriculum-weighted selective tests, HAST leans more heavily on abstract reasoning and open-ended writing, and its scores are referenced to a high-ability group. The safest approach is to ask the target school exactly which test, level and component package it uses.
