NSW Selective Thinking Skills: What's Actually Tested (With Example Questions)
What the Thinking Skills section of the NSW Selective test measures, the main question families and roughly how often each appears, how it differs from Maths and Reading, and how to help a child prepare.
Thinking Skills is the section parents find hardest to picture. Reading and Mathematical Reasoning have obvious school equivalents. Thinking Skills has none — there is no textbook, no unit of work, nothing on the Year 6 report card that maps to it.
This is an explainer: what the section is actually made of, why it exists, and what help genuinely transfers.
Where it sits in the test
The NSW Selective High School Placement Test is a computer-based exam sat in Year 6, on one allocated day at a designated test centre. It has four sections:
| Section | Time | Format |
|---|---|---|
| Reading | 45 minutes | 17 questions, 3 with multiple parts — 38 answers in all |
| Mathematical Reasoning | 40 minutes | 35 multiple-choice questions, no calculator |
| Thinking Skills | 40 minutes | 40 multiple-choice questions |
| Writing | 30 minutes | One extended response to a stimulus |
Two things follow from that row. First, at 40 questions in 40 minutes it is the tightest pace on the paper — a minute a question, including reading the question. Second, since 2025 all four sections carry equal weighting of 25% each. Thinking Skills used to count for more; it no longer does. It cannot be the whole preparation plan, and it cannot be skipped either.
What "thinking skills" actually means
The Department's framing is that the placement test measures academic potential rather than how much of the Year 6 syllabus a child has memorised. Thinking Skills is the purest expression of that. In practice, the information needed to answer a question is printed in front of the student — there is no assumed subject knowledge, and nothing in it can be revised in the way spelling or times tables can be revised.
What it does test is a set of habits of mind: following a chain of rules to something that must be true, noticing the assumption an argument is quietly resting on, holding several conditions in your head at once, and knowing when the information you have is genuinely not enough.
That last one is worth dwelling on, because it is where most marks leak. A great many wrong answers in this section are statements that are plausible, or that could be true, offered where the question asked what must be true. Children who have not been taught to feel the difference find those answers very attractive.
The main question families
Counting question types across the practice papers we have analysed, the section is less varied than its reputation suggests. It is dominated by verbal logic, with visual and spatial material a much smaller slice than parents usually expect. Approximate shares, from our own counts rather than any official breakdown:
| Family | Roughly | What it looks like |
|---|---|---|
| Deduction and logic puzzles | ~60% | Rules that lead to a conclusion; constraint and ordering puzzles; who-is-telling-the-truth statements |
| Argument analysis | ~19% | A short opinion or claim — find the hidden assumption, or the flaw that breaks it |
| Spatial and visual patterns | ~11% | Rotations and reflections, cube nets, paper folding, matrices and figure series |
| Reasoning from data | ~6% | A small table, chart or timetable, with a conclusion to draw from it |
| Codes and substitution | ~4% | Working out a rule that maps one set of symbols onto another |
| Sequences and analogies | ~1% | Number sequences; word relationships |
The practical read: if you only have limited time and want the best return, verbal deduction and argument analysis are where nearly four in five questions live. Spatial puzzles are the ones children enjoy most and the ones that matter least by volume.
Three examples
These are a deduction question, a constraint puzzle and an argument-analysis question — between them, most of the section. Tap a choice to grade it and read the explanation. The explanation is where the learning is, so read it even when the answer was right.

Notice how little content knowledge any of them needed, and how much careful reading each one needed. That ratio is the section in one line.
How it differs from Maths and Reading
The three multiple-choice sections look similar on screen and reward quite different things.
- Versus Mathematical Reasoning. Maths questions also involve multi-step reasoning, but they need number knowledge — fractions, measurement, place value — to get started. A Thinking Skills question with numbers in it is usually testing whether the student can reason with the information given, not whether they can calculate.
- Versus Reading. Reading asks what a text says, implies, or is trying to do, across passages long enough to get lost in. Thinking Skills texts are short — often three or four sentences — and the difficulty is entirely in the logical relationship between them, not in the vocabulary or the length.
- Versus Writing. No overlap at all, which is exactly why the equal 25% weighting matters. A child who loves puzzles can quietly neglect the section that now counts for just as much.
How to help your child prepare
The unusual thing about this section is that the highest-value help is conversational rather than written.
- Teach "must" versus "could". If all frogs are amphibians, that says nothing about whether all amphibians are frogs. Once a child can feel a rule being run backwards, a whole class of trap answers stops working on them. This is the single most useful idea in the section.
- Ask why the other options are wrong. Not just why the right one is right. Being able to say what makes an option merely plausible is the skill being measured.
- Slow the review down, not the practice up. Ten questions genuinely understood beat fifty rushed. Questions answered correctly by luck look identical to ones answered correctly by reasoning until someone asks.
- Practise abandoning a question. At a minute a question, sinking three minutes into one puzzle costs the two easy ones at the end. Making a reasoned choice, flagging it and moving on is a decision most eleven-year-olds have never been asked to make, and it transfers to every timed section.
- Read the stem carefully, twice. "Which must be true", "which weakens", "which assumption" — the wording changes the answer completely, and misreading it is a far more common cause of lost marks than faulty logic.
- Do it on a screen. The test is fully computer-based. Reasoning through a puzzle you cannot annotate with a pencil is a different experience, and it is better met in practice than on the day.
- Watch the pressure. If practice is producing dread or tears, ease off. A rested child reasons better than an exhausted one, and this is the section where tiredness shows first.
What not to do
Two traps are common. The first is drilling puzzle books for hours — repetition without review builds speed at the styles a child already gets right and leaves the misconceptions completely intact. The second is treating Thinking Skills as the section that decides everything because it feels the most like an intelligence test. It is one quarter of the result, sat by a tired eleven-year-old, on one morning.
