That is the Department's own description of the Thinking Skills test. It sounds reassuring. In practice it is the reason this section catches out capable students — because there is nothing in it that school revision can cover.
Across its description of the four Selective test components, the Department is specific about content for three of them. Reading draws on “non-fiction, fiction, poetry, magazine articles, reports”. Mathematical Reasoning bars calculators. Writing assesses “the creativity of the student’s ideas and their ability to write effectively for a purpose and audience”.
For Thinking Skills it says something different: “No previous knowledge is required for this test.”
Every other assessment a primary student has met rewards knowing things. Class tests, NAPLAN, homework — all of them ask a child to retrieve what they have been taught. Thinking Skills removes that entirely. Nothing a child has memorised helps.
The consequence is specific. A student at the top of their class can sit this section and find it genuinely unfamiliar, because their strength — knowing the material — has been designed out of it. Parents often read a strong school report and assume this section is covered. It is the one section a school report cannot predict.
The timing compounds it. Forty questions in forty minutes leaves about a minute each. A student meeting the format for the first time spends much of that minute working out what the question wants — not answering it.
There is no syllabus to cover. Anyone selling a Thinking Skills content list is selling something the test is designed to make irrelevant.
Familiarity with how the questions are put converts reading time into answering time. This is the single largest gain available, and it comes from working through the Department’s own practice materials.
Students do not fail this section uniformly. They fail on particular reasoning moves. Knowing which ones is more useful than a total score, because a total score does not tell you what to work on next.
You will find sites that break Thinking Skills into a fixed taxonomy of question types with percentages attached. The Department does not publish such a breakdown. We have not reproduced one here, because a categorisation that looks official but is not is worse than no categorisation at all. The Department’s practice tests are the authoritative sample.
It is one of the components of both the NSW Selective High School Placement Test and the Opportunity Class Placement Test. It measures reasoning rather than recall. The NSW Department of Education states that "no previous knowledge is required for this test".
In the Selective test it is 40 questions in 40 minutes and carries 25% of the placement score — the same weight as Reading, Mathematical Reasoning and Writing. It is also one of the three components of the OC test.
Because "no knowledge required" is not the same as "no skill required". A student unfamiliar with the question style spends their time working out what is being asked instead of answering it. With 40 questions in 40 minutes, that is the difference between finishing and not finishing.
Not directly. School assessment rewards recall and applied curriculum knowledge. Thinking Skills deliberately removes curriculum content from the equation, which is why a child can be at the top of their class and still find this section unfamiliar.
Yes. The Department publishes practice tests and sample questions for both the Selective and Opportunity Class placement tests through its parent and student resource pages. These are the only materials that reflect the real question style with certainty.
