HAST vs NSW Selective: Two Pathways, Compared

Some families arrive at Year 6 with two quite different processes running at once. One is the NSW public system: a single online application, one placement test, one offer. The other is a shortlist of independent or academically selective schools, several of which have asked for something called HAST.

They are not competing versions of the same thing, and the choice between them is rarely settled by the tests themselves. What follows is what actually differs — who runs each one, what a result leads to, and which parts of the preparation are genuinely shared.

What each one leads to

The NSW Selective High School Placement Test is run by the NSW Department of Education. It is sat in Year 6, and the result feeds a single centralised placement process: an offer of a Year 7 place at a government selective high school (which then runs to Year 12), a position on a reserve list, or neither. There is one sitting a year, one application, and from 2026 the test is held in NSW only. These are public schools, so tuition isn't part of the decision.

HAST — the Higher Ability Selection Test — is developed and administered by the Australian Council for Educational Research (ACER). Selective and independent schools around Australia use it — ACER's own participating schools list runs to around 80 across five states, plus one overseas — and not only for scholarships: some treat it as their main academic assessment for entry, some use it in scholarship decisions, and some use it to place students into academic streams. There is no central process. The school books the sitting, chooses which components your child sits, decides how the result is weighted, and makes the offer.

That difference is the one to hold on to. With selective, you are entering a system. With HAST, you are having a separate conversation with each school, and the school's own admissions page is the authority for everything below.

Who sits which, and when

The selective test is sat in Year 6, in early May, after an application window that runs from November to February. Our step-by-step guide to applying covers that form and its deadlines.

HAST comes in several levels, and ACER is explicit about how the level is chosen: it "is determined by the candidate's current year level at the time of the HAST test and not the age of the candidate". On ACER's test-level guide, students in Years 4 and 5 sit Primary (HAST-P), which ACER describes as being for entry into Years 5 and 6; from Year 6 they sit a Secondary level. So a Year 6 child applying for Year 7 entry at an independent school is sitting Junior Secondary, not the Primary paper — confirm the level with the school, because it changes what preparation is even relevant.

Schools also arrange their own sessions and set their own dates. ACER publishes no fixed testing window, so two children "doing the HAST" may sit on different dates, at different schools, with different sections in front of them. The HAST explainer sets out the other levels and the full section breakdown.

The differences that matter

	NSW Selective Placement Test	HAST (Primary)
Run by	NSW Department of Education	ACER, for individual schools
Who decides the outcome	A central placement process	Each school, on its own criteria
Sat in	Year 6	Depends on the level — Primary is sat in Years 4–5, for Year 5 or 6 entry
Where and when	NSW test centres, one sitting in early May	At the school, session dates set by the school — no fixed window
Components	Four, fixed: Reading, Mathematical Reasoning, Thinking Skills, Writing	Three or four at Primary: Reading Comprehension, Mathematical Reasoning and Written Expression, plus Abstract Reasoning if the school adds it
Sittings in a season	One	One per school that requires it
What a result leads to	A public school place, or a reserve list position	Entry, a scholarship, or streaming — as that school defines it

Two rows do most of the work for a family planning the year.

"Three or four." Each Primary component runs about 30 minutes — ACER puts Reading Comprehension and Mathematical Reasoning at 30–35 depending on the test form — so the school's package decides whether your child sits about an hour and a half of testing or closer to two hours, with short breaks between. Before you plan any preparation, ask the school which sections your child actually sits. It is a five-minute email that can save a term of misdirected work.

One sitting versus several. The selective test happens once. HAST happens as often as your shortlist requires it. That is a wellbeing question as much as a scheduling one, and it's worth counting the exam mornings honestly before the shortlist is final.

If independent schools are your main focus and you are also looking at scholarship exams, which Year 7 scholarship test your child will sit compares HAST with the ACER Scholarship Test, and selective place or scholarship? covers the other side of the same decision.

The one section that doesn't transfer

Both tests include a reasoning component with no classroom equivalent — but they are not the same component, and preparing for one does not prepare a child for the other.

The selective test has Thinking Skills, which leans on logical and verbal reasoning — deductions from a set of statements, arguments to pick apart, puzzles with several constraints to satisfy at once — alongside some visual and spatial questions. Here's one. Tap a choice to grade it and read the working.

HAST's equivalent is Abstract Reasoning, which is non-verbal: a pattern is shown and the child works out the rule. There is no content to revise, which is exactly why the format itself can be the obstacle the first time.

Note that Abstract Reasoning is one of the sections a school may or may not require. If it isn't on your child's paper, that's a term of pattern practice you don't need to do.

Where the preparation is genuinely shared

Underneath the different names, both are reasoning tests rather than curriculum quizzes, so families rarely need two separate programs:

• Reading closely, under time. Both draw on a range of text types and both reward inference, vocabulary in context, and reading for structure rather than speed.
• Multi-step maths where choosing the operation is the work. The numbers stay manageable in both; deciding what to do with them is the actual task.
• Planning a piece of writing fast. The selective test includes Writing; the Primary HAST packages include Written Expression. Either way the constraint is the clock — a usable plan in two or three minutes, then write.
• Familiarity with the format. Cheap to acquire, and it removes the first confused five minutes on the day.

The overlap is concrete enough that many maths questions sit in both banks. These two do — tap a choice to grade it and read the worked solution.

Nothing in either question belongs to a system or a sector. That is the general shape of the overlap: the reasoning is shared, and what differs is the packaging, the clock and who reads the result.

One practical difference on the day

The NSW selective test is sat on a computer, including the writing task, which makes keyboard fluency a real preparation item — a child who writes well by hand and hunts for keys is being slowed by the tool rather than the task. HAST arrangements are set by the school, so ask whether your child will be writing on paper or on screen. It is a small question that changes what a useful practice session looks like.

Can a child do both in one year?

Often, yes. The selective test is a single sitting in early May; HAST sessions are arranged school by school with no fixed window, so whether they collide is a question you can only answer school by school. Four cautions, in the order families trip over them:

• Check which HAST level the school is asking for. The level follows your child's current year level, so a Year 6 child applying for Year 7 entry is not sitting the Primary paper — which changes what preparation is even relevant.
• Registration deadlines are what get missed, not test dates. School registrations often close months ahead, and the NSW selective application window is separate again.
• Check each school's own session date before assuming there's no clash — including against the selective test itself.
• Count the mornings. Two or three school sittings plus the selective test is a lot of exam days for an eleven-year-old inside a single term.

How to choose, if you'd rather not do both

The useful question isn't which test is easier. It's which school you want your child at, and what happens if the answer is neither.

• What the place is worth to your family. A selective place is a public school place. A HAST result may lead to entry at a fee-paying school, a scholarship on terms that school sets, or a streaming decision — and those are quite different things to plan around.
• How the result is read. The selective system runs one centralised process with a single offer. HAST schools generally read the result alongside other evidence — ACER points schools to teacher nominations, a principal's recommendation, NAPLAN and school assessment data, and many schools add an interview — so one test day rarely decides everything on its own.
• What your child can carry. Twenty-minute sessions across a couple of terms looks very different from a term of intensive work and four exam mornings.

Whichever way you go, keep the framing plain with your child. Both processes are competitive by design, and an outcome either way is information about a particular school's places in a particular year — not a verdict on them.

If the decision is still open, the cheapest way to inform it is twenty minutes at the kitchen table with a handful of real questions from each. Most of what parents want to know — is this format a shock, is the reading a stretch, does the clock panic them — shows up in that first sitting.
