Quick Answer
Start with the official ACER HAST sample materials to set a baseline, then build a weekly routine combining sectional drills, vocabulary practice and timed writing. Across a nine- to twelve-month plan most students sit ten to fourteen full-length mock papers, reviewing every mistake thoroughly after each one.

- Writing practice1 timed task per week
HAST practice resources fall into three groups: official sample materials from ACER, structured drills and workbooks from Australian publishers, and the weekly materials used inside a guided programme such as the one offered by Braintree Coaching Australia. This page sets out what to use at each stage of the year, where to find verified materials, and how many full mock papers a child typically completes before the real sitting. For the broader picture — eligibility, levels and the application process — start with our HAST exam preparation hub, then return here to plan the practice itself.
Where can we get the official HAST sample materials?
The most reliable starting point for HAST preparation is the sample material published by the test administrator, ACER. These materials match the format, question style and difficulty of the real sitting, whereas third-party samples vary widely in quality and are best used as supplementary practice once the official baseline has been established.
- Australian Council for Educational Research (ACER) publishes the official HAST test information, component descriptions and sample questions. ACER builds and marks the paper, so its samples are the closest indicator a family can get of real question style and difficulty.
- ACER's assessment and research pages explain how cognitive ability tests are constructed and how results are referenced to a high-ability cohort rather than the general population — useful context when interpreting any practice score.
- Each participating school's own admissions page publishes the components it uses (three- or four-component package), its registration window and its sitting date. Because the HAST is administered directly by each school rather than from a central site, confirm these details on the target school's website before buying any resource.
Sit a HAST sample under timed conditions early in the preparation year as a diagnostic. Mark it carefully, identify the two weakest components, and use the result to shape the first three months of practice. A diagnostic that is not reviewed is wasted practice — set aside ninety minutes to mark and discuss it before the next attempt.
What kinds of practice materials does a HAST candidate actually need?
A complete HAST preparation kit covers four kinds of material: component-specific drills, full-length mock papers, vocabulary and writing rubrics, and a mistake-tracking log. Each addresses a different gap, and none replaces the others.
| Material | Purpose | Frequency |
|---|---|---|
| Component-specific drills (reading comprehension, mathematical reasoning, abstract reasoning) | Building accuracy on individual question types. | Daily, 20–30 minutes per session. |
| Full-length timed mock papers | Practising stamina, pacing and transitions across a 2–2.5 hour session. | Weekly in months 4–8; twice weekly in months 9–11. |
| Vocabulary lists with context sentences | Lifting reading comprehension and written expression scores. | 20 new words per week throughout the plan. |
| Writing prompts with rubrics | Improving structure, vocabulary and timing under a timed write. | One timed write per week. |
| Mistake log | Identifying recurring errors and stopping them recurring. | After every drill or mock paper. |
The single most important entry on this list is the mistake log. A student who reviews every wrong answer — and writes the type of mistake (not just the question) into a running list — improves significantly faster than one who simply sits more papers without review.
How many practice papers should a child sit?
A typical HAST preparation plan includes ten to fourteen full-length mock papers across nine to twelve months. The number matters less than the pacing: cluster mocks too early and the child plateaus; leave them too late and there is no time to act on the patterns.
- Months 1–3 (diagnostic and foundation). One full-length paper early as a baseline (an ACER sample), and one more at the end of month three. The goal in this phase is accuracy under untimed conditions — not yet pace.
- Months 4–8 (skill building). One full-length paper every two to three weeks (about three to four papers in this phase), plus two timed component papers each week. Review every paper carefully before sitting the next one.
- Months 9–11 (mastery). One full-length paper per week, sat in real conditions — timed, scored, no notes. Most students sit five to eight papers in this phase.
- Final four weeks (taper). One or two full-length papers in the first fortnight, then taper to vocabulary, mental-maths and abstract-reasoning review only. No new mock papers in the final week.
A child who sits twelve mocks with thorough review reliably outperforms one who sits twenty-five without it. The review is where the marks are made. For a fuller week-by-week build-up, see our HAST test preparation strategies.
What should we look for in a paid HAST question bank?
Paid third-party question banks vary considerably in quality. Before committing budget to one, check it against four criteria:
- Difficulty matched to the real test. Compare a sample question to the official ACER material. If the third-party questions are noticeably easier or harder — particularly in mathematical reasoning and abstract reasoning — the bank will not predict real performance.
- Solutions that explain the reasoning, not just the answer. A bank that returns "B" without explanation does not help a student improve. Look for solutions that name the inference in a reading passage, the step in a maths problem or the transformation rule in an abstract reasoning item.
- Coverage across every component the child will sit. A school using the four-component package needs written expression coverage; a three-component package may not. Question banks that skip a component the school actually uses leave part of the paper unprepared.
- Access through to the sitting. Some banks expire after thirty or sixty days. Confirm the access window covers the run-up to the real test date.
Official sample materials from ACER, combined with a structured weekly routine, are sufficient for most families. A paid bank is a supplement, not a substitute for reviewing every mistake.
How should writing practice fit into the plan?
Written expression is the HAST component that responds fastest to deliberate practice but is the most often neglected. One timed thirty-minute write per week, marked against a clear rubric covering ideas and content, organisation, language and vocabulary, and conventions, lifts writing scores faster than any other single intervention.
- Plan first. Five minutes of planning at the top of the timed write produces a stronger piece than the same time spent writing without a plan. The strongest pieces almost always have a written outline before the first sentence is drafted.
- Mix forms. Alternate weeks between creative narrative and persuasive writing — the test sets one or the other and neither child nor parent knows which on the day.
- Track structure, not topic. Most marks are won and lost on structure (introduction, body paragraphs, conclusion) rather than on topic. A child writing a polished structure on an unfamiliar topic outperforms a child writing an unstructured piece on a comfortable topic.
Schools using a three-component package may omit written expression altogether, so confirm the components your target school uses before weighting writing practice in the plan.
How should the abstract reasoning component be practised?
Abstract reasoning is the HAST component that measures non-verbal pattern recognition, and it rewards methodical practice with rotation, reflection, sequence and matrix puzzles. It is often the component that separates strong general students from the very top of the high-ability cohort the test is referenced against.
A workable weekly routine in months 4–8: two 25-minute timed drill sessions per week covering a mix of rotation, reflection, size, shading and sequence items, plus one mixed-pattern session at the end of the week to build cross-pattern recognition. Because the HAST is reported in percentiles and stanines against a high-ability cohort, small gains in a hard component like abstract reasoning can move a child several percentile points.
When marking abstract reasoning practice, ask the child to name the rule for every item — right or wrong. A correct guess without a named rule is no more reliable than a wrong answer; only a named rule generalises to the next item.
What does this mean for preparation?
Start with the official ACER sample materials, build a weekly routine of component drills, vocabulary and one timed write, then add full-length mocks at the pace of the four-phase plan. Pair this page with our HAST test format guide to understand what each component measures and how results are scored, and with our HAST test preparation strategies to see how these resources fit into a full preparation timeline. Above all, confirm with the target school which components it uses and when it sits the test, because the HAST is administered school by school rather than centrally.
