BSHS HAST preparation: a four-phase, twelve-month plan

The Brisbane State High School HAST rewards methodical preparation over nine to twelve months. For Year 7 entry from Year 5, Brisbane State High publishes a HAST-P battery of three timed components — Reading Comprehension (35 minutes), Mathematical Reasoning (35 minutes) and Written Expression (30 minutes). Year 6 applicants sit HAST Secondary; the school does not publish per-component timings for that sitting on its Academic Selective Entry page, and ACER's Secondary battery includes Abstract Reasoning alongside Mathematical & Scientific Reasoning, Reading Comprehension and Written Expression.

The Higher Ability Selection Test is built and marked by the Australian Council for Educational Research (ACER); ACER's HAST programme overview describes the Primary and Secondary levels schools can choose from. Application windows, fees and sitting arrangements for Brisbane State High are published on the school's Academic Selective Entry page, within the broader selective-entry framework maintained by the Queensland Department of Education.

This page sets out a four-phase plan, the weekly hours to budget for, and the techniques that work best in each section — see our BSHS selective entry preparation programme for the corresponding classroom course, and our BSHS HAST exam format overview for the section-by-section structure of the paper.

When should we start preparing for the BSHS HAST?

Plan to start nine to twelve months before the sitting. Brisbane State High publishes one Academic Selective Entry sitting date per entry year on its enrolment page (for the 2026 calendar, Year 5 applicants toward Year 7 2028 sat in late July, and Year 6 applicants toward Year 7 2027 sat in late April) and does not offer alternative dates, so the lead time depends on the child's current school performance and that published date. As a guide:

Current school performance	Recommended lead time	Weekly study commitment	Focus
Consistently top 10%	9 months	4 hours	Refining technique and pace across each section.
Consistently top 20–30%	12 months	5 hours	Building vocabulary, reasoning patterns and writing sophistication.
Middle of the year group	18–24 months	6 hours	Foundational skill-building, extended practice and gradual difficulty progression.

Spread practice across the week. A child who studies for six hours on a Saturday will retain less than one who studies for an hour on six days. Aim for 30–60 minutes most weeknights and a longer block on the weekend for a timed sectional or full mock paper.

What does each preparation phase cover?

The plan moves through four phases. Each phase ends when the child reaches the success markers below — not when the calendar runs out — so a student who is ahead can move on, and a student who is behind can hold position and consolidate.

1. Diagnostic and foundation (months 1–3). Sit a full-length, timed diagnostic paper in week one. Mark it carefully and identify the three weakest areas; design the term around closing those gaps. Build a daily routine across reading, mathematical reasoning and short writing tasks, and add abstract reasoning for Year 6 candidates. By the end of month three, baseline accuracy should sit at 70–75% across the multiple-choice sections and the child should be comfortable with the test format and on-paper instructions.
2. Skill development (months 4–8). Increase the difficulty of practice and start tracking time per question. Targets at this stage: confident handling of multi-step word problems, fluent recognition of the major abstract reasoning patterns (rotation, reflection, size, shading, sequence), a working vocabulary at year 8–9 level, and a planned writing task matched to the school's published Written Expression timing (30 minutes on the Year 5 HAST-P battery) that scores in the upper band on the writing rubric you use in practice. Complete six to eight full-length mock papers in this phase, and review each paper carefully — the value sits in the review, not the score.
3. Mastery and test simulation (months 9–12). Move into weekly full-length mock papers under real test conditions: timed and scored, working by hand without a calculator, no notes. Aim for 80–85% accuracy across the multiple-choice sections and consistent writing rubric scores of 80%+. By the end of this phase, the child should be finishing each section with two to five minutes to review, recognising abstract reasoning patterns on sight, and confident enough to leave a hard question and move on under pressure.
4. Final-month tapering and test-day readiness. In the last four weeks, taper rather than cram. Sit one or two full-length papers in the first fortnight, then taper down to light vocabulary, mental-math and abstract reasoning review only. In test week, no new material — focus on sleep, nutrition and the test-day logistics (route, photo ID, water bottle, permitted materials). The goal of the final month is to arrive rested and confident, not to learn anything new.

How should the week be structured?

A productive week balances skill work, timed practice and review. A typical phase-two schedule looks like this:

• Monday — abstract reasoning practice for Year 6 candidates (30 minutes), or mental arithmetic and number patterns for Year 5 (30 minutes).
• Tuesday — reading comprehension, two timed passages with full question sets followed by mistake review.
• Wednesday — mathematical reasoning, 45 minutes focused on the weakest strand identified in the diagnostic.
• Thursday — mixed reasoning and mental-math drills under time pressure, with one short reading passage at the end.
• Friday — a 25-minute timed write against a HAST-style prompt, followed by self-assessment against the rubric.
• Saturday — one full-length sectional or mock paper, sat in real conditions.
• Sunday — review of the week's mistakes and patterns; light vocabulary refresh.

Adjust the volume to suit the phase: 45 minutes per session in phase one, 75 minutes per session in phase three. Keep one day each week genuinely off — fatigue accumulates over a year, and a tired child loses marks they would otherwise hold.

What strategies work best in each section?

Abstract reasoning (Year 6 HAST only). Check each pattern against five attributes in turn — rotation, reflection, size, shading and number — before scanning the options. Most errors come from leaping to the answer before naming the rule. Eliminate visibly wrong options first, then test the remaining options against the rule. Hold one minute per question as the maximum and skip rather than guess if the rule is not visible after that minute.

Reading comprehension. Read the questions before the passage, then read the passage with the questions in mind. Return to the text to verify every answer — never rely on memory for inference questions, where the test rewards specific textual evidence over plausible interpretation. Eliminate options containing absolute words ("always", "never", "only") that are not directly supported by the passage.

Mathematical reasoning. Draw a diagram for every geometry and word problem. Sanity-check the answer against what the question actually asks (perimeter versus area, minutes versus hours, units). Working backwards from the answer choices is often faster than algebra for two- and three-step problems, particularly under time pressure. Apply the difference method to number sequences: find the differences between consecutive numbers, then the differences of those differences.

Written expression. Use a 5-20-5 split inside the 30 minutes: five minutes planning, twenty minutes writing, five minutes editing. A planned piece beats an unplanned one almost every time; an unplanned 30-minute write tends to lose marks for structure and conclusion. Vary sentence structures and avoid stock openings ("My name is…", "Once upon a time…"). Build a working list of stronger verbs and connectives to draw on under time pressure.

What are the most common mistakes to avoid?

A handful of mistakes recur across every cohort we prepare. They cost marks in any single section, and they compound when a child carries them across the whole paper:

• Leaping to the answer in abstract reasoning before naming the rule. A student who names the change ("rotation by 90 degrees, then a shading swap") before scanning the options is significantly more accurate than one who picks the option that "looks right".
• Verifying a number sequence on only two values. A pattern that fits the first two differences may break on the third — check three before committing.
• Answering reading questions from memory. Inference questions reward returning to the passage; opinion-based reading loses marks the test is designed to catch.
• Misreading what the maths question asks. Underlining the units and the requested quantity (area, perimeter, hours, minutes) takes five seconds and prevents a whole-question loss.
• Writing without a plan. A weak conclusion is almost always a sign of a missing plan, not a missing idea.

Build mistake review into the routine. After every sectional or mock paper, write the type of mistake (not just the question) into a running list. Patterns become visible quickly and the same mistake stops recurring.

What does this mean for preparation?

A twelve-month plan rewards consistency over intensity. Hold the weekly schedule, review every mock paper carefully, and protect sleep in the final fortnight. Pair this plan with our BSHS HAST exam format overview to understand what each section measures, and with our BSHS HAST practice resources for the materials we use in class. Before you build the schedule, check the application windows and fee in our Brisbane State High selective entry guide — the school runs one sitting per entry year and offers no alternative dates, so the deadline sets the plan.
