HAST Test 2026: Complete Preparation Guide, Practice Resources & Expert Tips

The HAST (Higher Ability Selection Test), developed by ACER, is used by 78 schools across five states, plus one international school, to select students for gifted programs and scholarships. It tests reasoning ability, not memorised content, across Reading, Mathematical Reasoning, Abstract Reasoning, and Written Expression. It is available at HAST-P (primary) and HAST Secondary levels.

Your Complete Guide to the HAST Test in 2026

The Higher Ability Selection Test (HAST) is one of Australia's most widely used selective school entrance assessments, administered by 78 schools across five states. Developed by the Australian Council for Educational Research (ACER), an organisation with more than 50 years of experience in educational assessment, the HAST is specifically designed to measure skills and aptitude, not retrieved knowledge.

Whether your child is sitting for entry into Year 5 or Year 11, understanding how the HAST works is the first step towards effective preparation. This guide from Braintree Coaching Australia draws directly from ACER's official information and participating school details to give you everything you need.

What Is the HAST?

The Higher Ability Selection Test is a standardised assessment developed and administered by ACER (Australian Council for Educational Research), one of the world's most established independent educational research organisations. With over 50 years of expertise in test design, ACER creates assessments used by schools, universities, and governments across the globe.

Purpose: Skills and Aptitude, Not Memorised Content

The HAST is deliberately designed to assess skills and aptitude rather than retrieved knowledge. This distinction matters enormously for preparation. Unlike curriculum-based exams where students can memorise facts and formulas, the HAST evaluates how well a student can reason, analyse, and think critically — regardless of which school they attend or which textbooks they use.

This approach means two things for families:

1. The playing field is more level: students from different schools and backgrounds are assessed on their thinking ability, not their access to specific content
2. Preparation should focus on building skills: practising reasoning strategies and analytical thinking is far more effective than rote learning

Two Levels: HAST-P and HAST Secondary

ACER offers the HAST at two distinct levels to serve students across a wide age range:

• HAST-P (Primary): designed for students seeking entry into Years 5 and 6
• HAST Secondary: available in Junior, Middle, and Senior levels for students seeking entry into Years 7 through 11

Both levels assess the same four core skill areas, though the complexity and content are calibrated to each age group. All HAST assessments are paper-based — there is no computer-based option.

How HAST Differs from Other Selective Tests

If you're familiar with the NSW Selective High School Placement Test or other state-based assessments, the HAST has several distinctive features worth noting. The NSW Selective Test is now fully computer-based and is a single standardised test for all government selective schools. The HAST, by contrast, is paper-based, administered by individual schools on dates they choose, and used by both government and non-government schools across five states.

The HAST's emphasis on aptitude over curriculum knowledge also sets it apart. While all selective tests incorporate reasoning elements, the HAST is built from the ground up around the principle of measuring thinking skills rather than what a student has been taught.

HAST-P vs HAST Secondary: Which Level Does Your Child Need?

Understanding the difference between the two HAST levels is essential for registration and preparation. The level your child sits depends entirely on which year of school they're seeking entry into.

HAST-P (Primary)

HAST-P is designed for younger students entering selective or gifted programmes at the primary level (Years 5–6). It assesses four components:

1. Reading Comprehension
2. Mathematical Reasoning
3. Abstract Reasoning
4. Written Expression

The content and difficulty are age-appropriate for primary-aged students, but the questions still require genuine reasoning ability, not simply recalling what's been taught in class.

HAST Secondary

HAST Secondary serves students across a broader age range, with Junior, Middle, and Senior sub-levels covering entry from Years 7 to 11. The four components are:

1. Reading Comprehension
2. Mathematical & Scientific Reasoning (note: this includes scientific reasoning, unlike the primary level)
3. Abstract Reasoning
4. Written Expression

The inclusion of scientific reasoning in the secondary level reflects the broader analytical skills expected of older students. This doesn't mean students need to memorise science facts — rather, they need to demonstrate scientific thinking and logical analysis.

Test Components Breakdown

Both HAST-P and HAST Secondary assess four core skill areas. ACER does not publish per-component question counts or time limits, so the breakdown below focuses on what each component assesses rather than inventing numbers ACER hasn't confirmed. Ask your target school for its exact test schedule.

HAST-P Component Details

Reading Comprehension

The Reading Comprehension component presents students with a variety of text types and asks questions that assess their ability to understand, interpret, and analyse what they've read. Questions range from straightforward comprehension to more complex inference and critical analysis tasks.

What it assesses:

• Understanding of main ideas and supporting details
• Ability to draw inferences from textual evidence
• Vocabulary understanding in context
• Critical evaluation of author's purpose, tone, and perspective
• Ability to synthesise information across a passage

Because this component tests reading skill and aptitude rather than prior knowledge, the passages cover diverse topics that don't require specialist background knowledge.

Mathematical Reasoning

Mathematical Reasoning evaluates a student's ability to think logically and solve problems using mathematical concepts. The emphasis is on reasoning processes, not computational speed or memorised procedures.

What it assesses:

• Pattern recognition and logical sequences
• Problem-solving with multi-step reasoning
• Spatial and proportional thinking
• Application of mathematical concepts to unfamiliar contexts
• Ability to identify relevant information and filter distractions

Students don't need to have covered advanced mathematics. The test is designed to measure how well they can think mathematically, not what content they've been taught.

Abstract Reasoning

Abstract Reasoning is often the most distinctive component of the HAST. It presents non-verbal, visual puzzles that assess pure logical thinking, independent of language ability, cultural background, or specific educational experiences.

What it assesses:

• Visual pattern recognition and completion
• Logical sequence identification
• Spatial relationships and transformations (rotation, reflection, scaling)
• Classification and categorisation of abstract shapes
• Rule identification and application

This component is particularly important because it measures reasoning ability in its purest form, without the influence of language or learned content.

Written Expression

Written Expression is the only component that isn't multiple-choice. ACER's own HAST page states students choose between a discursive or creative response, and that Written Expression is assessed by qualified human markers.

What it assesses:

• Ability to develop and organise ideas coherently
• Quality of argument, narrative, or exposition
• Vocabulary range and accuracy
• Sentence structure variety and control
• Grammar, spelling, and punctuation

HAST Secondary Components

The HAST Secondary shares three components with HAST-P (Reading Comprehension, Abstract Reasoning, and Written Expression) but replaces Mathematical Reasoning with Mathematical & Scientific Reasoning. This expanded component assesses:

• All the mathematical reasoning skills tested in HAST-P
• Scientific thinking and logical analysis
• Interpretation of scientific data and relationships
• Hypothesis evaluation and evidence-based reasoning

The inclusion of scientific reasoning doesn't require memorised science content. Instead, it tests a student's ability to think like a scientist — analysing data, identifying patterns, and drawing evidence-based conclusions.

Participating Schools: 78 Across Five States

ACER's own participating-schools page lists 78 schools using the HAST: NSW (28), VIC (24), QLD (11), SA (8), and WA (6), plus one international school in Singapore. Unlike centralised state tests, each school independently decides to use the HAST and manages its own registration, test dates, and admissions processes. New schools join over time, so treat the notable examples below as a starting point and confirm current status with your target school or ACER's own list.

New South Wales (28 Schools)

NSW has schools on ACER's HAST participating-schools list for school-run HPGE, scholarships, or later-year processes. That is not the same as Year 7 entry to NSW DoE fully or partially selective high schools, which use the Selective High School Placement Test. Confirm each school's instrument on its own enrolment page.

Notable NSW schools include:

• Fort Street High School (Senior level only), one of Sydney's most prestigious selective schools
• Girraween High School, a highly sought-after selective school in Western Sydney
• Hornsby Girls High School and Cheltenham Girls High School, high-ranking girls' selective schools
• Epping Boys High School and Homebush Boys High School, prominent boys' selective schools
• Hurlstone Agricultural High School, a unique selective school with an agricultural focus
• Sydney Grammar Edgecliff (Primary), which uses HAST for primary-level entry
• Sydney Catholic Schools Newman Program, a Catholic schools gifted programme using HAST

Victoria (24 Schools)

Victoria has a substantial network of HAST-participating schools, including:

Notable VIC schools: Balwyn High School, Box Hill High School, Cheltenham Secondary College, Dandenong High School, St Helena Secondary College, and Wheelers Hill Secondary College, plus other schools across metropolitan and regional areas.

Queensland (11 Schools)

Queensland's HAST schools include some of the state's most competitive selective entry programmes:

Notable QLD schools:

• Brisbane State High School, Queensland's most prominent HAST school and one of the most competitive selective entry schools in the state
• Benowa State High School, Brisbane South State Secondary College, Indooroopilly State High School, Murrumba State Secondary College, Narangba Valley State High School, Palm Beach Currumbin State High School, Robina State High School, and The Southport School

South Australia (8 Schools)

South Australia's HAST schools include several operating under the IGNITE programme for gifted students:

Notable SA schools: Aberfoyle Park High School (IGNITE), Glenunga International High School (IGNITE), The Heights School (IGNITE), Adelaide Botanic High School, and Norwood International High School.

Western Australia (6 Schools)

Western Australia's HAST schools are often missing from summaries of the programme, but WA is fully covered:

Notable WA schools: Churchlands Senior High School, Mount Lawley Senior High School, Carey Baptist College, Mandurah Baptist College, Harrisdale Senior High School, and Piara Waters Senior High School.

Registration & Key Dates

Unlike centralised state-run selective tests, HAST registration is managed by each individual school. This means there is no single registration portal, no universal test date, and no state-wide application deadline.

How Registration Works

Key Timing Considerations

Because each school sets its own schedule, there is no single "HAST test date" to prepare for. However, there are important patterns to be aware of:

• Schools choose their own test date: this can vary significantly between schools
• Registration opens at different times for each school — contact your target school early to avoid missing deadlines
• Results turnaround is 10 working days: ACER processes and returns results within this timeframe
• You can sit the HAST at multiple schools: if your target schools hold tests on different dates, you may be able to apply to more than one

Results and Reporting

Once the test is complete, ACER scores and reports the results:

• Multiple-choice components (Reading Comprehension, Mathematical/Mathematical & Scientific Reasoning, Abstract Reasoning) are machine scored
• Written Expression is assessed by qualified human markers
• Schools receive both individual student reports and a school ranking report
• ACER provides free help interpreting results — schools can contact ACER for guidance on understanding reports

Preparation Strategy & Timeline

Because the HAST tests skills and aptitude rather than retrieved knowledge, preparation should focus on building thinking capabilities over time. Cramming facts won't help — but consistent practice in reasoning, analysis, and written expression will make a genuine difference.

Daily Practice Routine

A consistent daily routine is more effective than sporadic intensive study sessions. Here's a balanced approach:

Weekdays (30–45 minutes total):

• 10–15 minutes: Reading a challenging text and answering comprehension questions
• 10–15 minutes: Mathematical reasoning or abstract reasoning practice (alternate daily)
• 10 minutes: Vocabulary building through wide reading or word study

Weekends (60–90 minutes, one session):

• Complete a timed practice section for one component
• Write a timed Written Expression practice piece
• Review the week's errors and identify improvement areas

The Aptitude vs Knowledge Distinction in Practice

Because the HAST tests aptitude, your preparation approach should reflect this:

• Don't drill multiplication tables or memorise science definitions
• Do practise solving unfamiliar problems using logic and reasoning
• Don't have your child memorise essay templates or vocabulary lists
• Do encourage wide reading, discussion of ideas, and regular writing practice
• Don't focus on covering specific curriculum content
• Do build flexible thinking through puzzles, debates, and open-ended questions

Subject-Specific Tips

Each of the four HAST components requires a slightly different preparation approach. Here are targeted strategies for each.

Reading Comprehension Strategies

The Reading Comprehension component rewards students who can engage deeply with unfamiliar texts and extract meaning efficiently. ACER does not publish an exact question count or time limit, so practise working steadily rather than rushing to a target pace you can't confirm.

Preparation strategies:

• Read widely and diversely: expose your child to fiction, non-fiction, scientific articles, opinion pieces, historical texts, and poetry. The HAST draws from varied text types, so breadth of reading experience is valuable.

• Practise inference skills: the most challenging questions ask students to read between the lines. After reading a passage, ask: "What does the author imply but not directly state?" and "What evidence supports this conclusion?"

• Build contextual vocabulary: rather than memorising word lists, practise working out word meanings from surrounding context. This mirrors what the test actually requires.

• Use the text, not your memory: train your child to always refer back to the passage when answering questions, rather than relying on what they think they remember.

Mathematical Reasoning Strategies

Mathematical Reasoning (or Mathematical & Scientific Reasoning for HAST Secondary) focuses on problem-solving ability, not computational speed. Question counts and time limits aren't published by ACER, so build pacing habits your child can apply to whatever schedule the test day brings.

Preparation strategies:

• Focus on patterns and relationships: many questions involve identifying number patterns, geometric sequences, or logical relationships. Practise looking for the underlying rule rather than trying to calculate every possibility.

• Break complex problems into steps: train your child to read the full question, identify what information is given, determine what needs to be found, and work through the solution logically.

• Practise estimation and elimination: for multiple-choice questions, eliminating obviously wrong answers narrows the field and saves time. Estimation skills help identify whether an answer is reasonable.

• Work with unfamiliar problem types: because the HAST tests aptitude, your child may encounter problems they haven't seen in school. Practise approaching unfamiliar questions with curiosity rather than anxiety.

• For HAST Secondary: develop scientific reasoning by practising data interpretation, hypothesis evaluation, and evidence-based analysis. Read scientific articles and discuss what the data shows.

Abstract Reasoning Strategies

Abstract Reasoning is purely visual and non-verbal, making it one of the most level components of the HAST. ACER doesn't publish a question count or time limit for this component, so pace practice around steady, consistent working rather than a specific target time.

Preparation strategies:

• Learn to identify what changes: in pattern sequences, systematically check what changes between frames: shape, size, colour, position, orientation, number of elements. Identifying the rule is the key skill.

• Practise multiple question formats: abstract reasoning questions come in several formats: sequence completion, odd-one-out, matrix patterns, and analogies. Familiarity with each format reduces test-day surprises.

• Use process of elimination: if you can't immediately see the pattern, eliminate answer options that clearly don't follow the rule you're testing.

• Don't overthink: abstract reasoning questions typically follow clean, logical rules. If your reasoning becomes overly complex, step back and look for a simpler explanation.

• Time yourself: since ACER doesn't publish a time limit, practise working at a brisk, steady pace rather than lingering on any one question. Flag difficult questions and return to them if time permits.

Written Expression Strategies

Written Expression is unique among the HAST components: it's the only one that isn't multiple-choice, and it's assessed by qualified human markers rather than machine scored. ACER's own HAST page confirms students choose between a discursive or creative response. This is where practice has an enormous impact.

Preparation strategies:

• Practise planning quickly: under exam time pressure, your child should spend only a few minutes planning before writing. Practise jotting down a quick structure first.

• Focus on idea development: markers value original thinking, clear reasoning, and well-developed ideas. Encourage your child to go beyond surface-level responses.

• Vary sentence structures: strong writers mix short and long sentences, use different sentence openings, and demonstrate vocabulary range. Practise this variety explicitly.

• Write legibly: since the HAST is paper-based, handwriting must be legible for markers to assess the work fairly. If your child's handwriting is difficult to read, dedicate time to improving clarity.

• Practise under timed conditions: writing a quality response against the clock requires regular timed practice. Start with longer time limits and gradually reduce them as your child becomes more comfortable.

Test Day Guide

Knowing what to expect on test day helps reduce anxiety and ensures your child can focus entirely on performing their best. Because the HAST is paper-based and administered by individual schools, the test day experience may vary slightly between schools — but these essentials apply universally.

Timing and Pacing

ACER does not publish per-component time limits, so confirm the exact schedule with your target school before test day. In the meantime, the same pacing habits apply across all four components:

Reading Comprehension: Read the passage carefully first, then answer the questions. Return to the text for evidence rather than relying on memory. If a question is taking too long, mark your best guess and move on.

Mathematical Reasoning: Work methodically through each question. Show your working on scratch paper if provided, as this helps you track your reasoning. Don't dwell on any single question; flag difficult ones and return to them.

Abstract Reasoning: Identify the pattern rule, apply it, and move on. Don't second-guess yourself if your first analysis seems logical.

Written Expression: Spend a few minutes planning before writing, leave time at the end for a quick review, and practise this rhythm so it feels automatic under time pressure on the day.

Managing Test Anxiety

Some nervousness on test day is normal and can even be helpful — it keeps your child alert and focused. But excessive anxiety can undermine performance. Here's how to help:

• Normalise the experience: talk about the test as an opportunity, not a threat. Your child's worth isn't determined by a single test.
• Practise the routine: if possible, visit the test venue beforehand so it feels familiar. Practise the morning routine in advance.
• Deep breathing: teach your child a simple breathing technique: breathe in for four counts, hold for four counts, breathe out for four counts. This can be used between sections or during moments of stress.
• Focus on the next question: if a question feels overwhelming, skip it and focus on the next one. Returning to difficult questions later, with fresh eyes, often helps.
• Get a good night's sleep: no amount of last-minute revision is worth sacrificing sleep. Ensure your child is well-rested and has a calm evening before the test.

Frequently Asked Questions

What exactly is the HAST, and who develops it?

The Higher Ability Selection Test (HAST) is a standardised assessment developed by ACER (Australian Council for Educational Research), an independent educational research organisation with over 50 years of experience. It measures skills and aptitude rather than retrieved knowledge, and is used by 78 schools across five states (NSW, VIC, QLD, SA and WA), plus one international school, for selective entry, scholarship and gifted-education decisions.

What are the four components of the HAST?

Both HAST-P and HAST Secondary assess four components. Reading Comprehension, Mathematical Reasoning (or Mathematical & Scientific Reasoning for Secondary), Abstract Reasoning, and Written Expression. The multiple-choice components are machine scored, and Written Expression is assessed by qualified human markers, with a choice between a discursive or creative response.

Is the HAST paper-based or computer-based?

All HAST assessments are paper-based only. There is no computer-based option. Your child will read passages, answer multiple-choice questions, and handwrite their Written Expression response entirely on paper.

How long does the HAST take?

ACER does not publish a single official total duration or per-component time limit for the HAST. Schools set their own schedules, so contact your target school for the exact timing your child's sitting will use, and build up to full-length, timed practice sittings so your child is comfortable with a paper-based test of several hours.

How do I register my child for the HAST?

Registration is managed by each individual school, not by ACER centrally. Contact your target school's enrolments or admissions office directly to inquire about registration deadlines, required documentation, and testing dates. Schools also choose their own test dates, so timing varies. Start the process early to avoid missing deadlines.

When will we receive HAST results?

ACER provides results within 10 working days of the test. Schools receive individual student reports and a school ranking report. ACER also provides free assistance interpreting results — schools can contact ACER for guidance on understanding the reports.

Can my child sit the HAST at more than one school?

Because each school chooses its own test date and manages registration independently, it may be possible to sit the HAST at multiple schools if their test dates don't overlap. Contact each school to confirm their test date and whether they accept results from HAST sittings at other schools.

How should we prepare if the HAST tests aptitude, not knowledge?

Focus on building thinking skills rather than memorising content. Practise reasoning and problem-solving with unfamiliar question types. Read widely to build comprehension and inference skills. Practise writing under timed conditions to develop fluency and idea generation. Work through abstract reasoning puzzles regularly. The key is developing flexible, analytical thinking, the kind of preparation that can't be crammed in a weekend. Consider structured preparation programmes like Braintree's HAST Exam Preparation course for guided, expert-designed practice.
