Introduction

For many Perth families, Perth Modern School sits at the very top of the wish list, and for good reason. It is the only fully academically selective public school in Western Australia, which means a place is free, government run, and won purely on merit. That also makes it one of the hardest places in the state to get into.

The trouble is that the path is wrapped in unfamiliar language. Parents hear about the ASET, the Total Standard Score, and a cut off that seems to shift every year, and it is hard to know what any of it really means for their own child. Misunderstanding these terms can lead to false hope or needless worry.

This guide clears the fog. It explains the Perth Modern School entry requirements in plain terms, shows how the Total Standard Score actually works, sets out what the cut off score has been recently, and explains why it changes. Most importantly, it covers what it genuinely takes to win a place, beyond chasing a single number.

By the end, you will understand exactly how entry works, what score your child realistically needs, and where to focus their preparation. You will also see how this fits alongside the wider GATE pathway, so that whatever the outcome, your child has strong options across Perth, including comparing the top GATE schools in WA.

What Are the Perth Modern School Entry Requirements?

The Perth Modern School entry requirements are refreshingly simple to state: entry is based solely on a child’s result in the Academic Selective Entrance Test, known as the ASET. There is no interview, no portfolio, no catchment area, and no sibling priority for the academic places.

This is what makes Perth Modern different from almost every other school. The entire school is academically selective, so every student earns their place through the same test, sat in Year 6 for entry into Year 7. Where your family lives makes no difference to selection, and neither does which primary school your child attended.

A few eligibility basics apply. The applicant must be entering Year 7 in the relevant year, and must be an Australian or New Zealand citizen or a permanent resident of Australia. The test itself is free, and families apply through the Department of Education during the application window.

Because selection rests on a single test, everything comes down to how your child performs across the four sections of the ASET on the day. That places enormous weight on understanding the score that test produces, and how it is used to decide who receives an offer. For more detail, see our guide on understanding the ASET exam format.

So while the entry requirement is easy to describe, succeeding against it is not. The next step is understanding the number at the heart of it all, the Total Standard Score.

What Is the Total Standard Score, and How Does the TSS Work?

The Total Standard Score, or TSS, is a single number out of 400 that combines your child’s results across the four ASET sections, standardised by the Australian Council for Educational Research. It is the number the Department of Education uses to rank every applicant for selective entry.

The four sections each carry equal weight: reading comprehension, writing, quantitative reasoning and abstract reasoning. Your child’s performance in each is converted to a standardised score, and those four scores are added together to produce the TSS. Because the sections are weighted equally, no single one matters more than another.

Here is the detail that confuses many parents, and it matters enormously. The TSS is a standardised score, not a percentage and not a percentile. A score of 244 out of 400 does not mean your child answered 61 per cent of questions correctly. The scores are normalised against how every other child performed that year, so the number reflects relative standing, not a raw mark.

This explains why families are sometimes caught out. A child can feel the test went well and still fall just short, because the score depends on the strength of the whole cohort, not on a fixed pass mark. Understanding the Perth Modern TSS as a ranking tool, rather than a school style percentage, sets realistic expectations from the start.

Once you see the TSS this way, the idea of a cut off score becomes much clearer, because the cut off is simply where the ranking falls in any given year.

What Is the Perth Modern Cut Off Score?

The Perth Modern cut off score is the TSS of the last student offered a place in a given year, and in recent intakes it has sat around 244. For the 2026 academic intake, the cut off was a TSS of 244.34, while in 2024 it was closer to 247.

It is important to understand what this figure represents. The Department of Education does not officially publish a fixed cut off, because there is not one. Perth Modern simply ranks all applicants by TSS and makes offers from the top down until its places are filled. The cut off is whatever score the final successful applicant happened to achieve.

For context, a minimum TSS of 209.5 is generally required even to be considered for any GATE academic program, and Perth Modern sits far above that baseline. The roughly 244 mark in recent years places a child near the very top of the applicant pool, which is exactly why it is the most competitive entry point in the state.

The scale of competition is striking. Perth Modern offers only around 225 Year 7 places each year, and in 2024 approximately 7,000 students sat the ASET. That means a Perth Modern offer typically requires a child to finish among the top few per cent of all candidates.

So when you see a Perth Modern ASET score quoted online, treat it as a recent guide rather than a guaranteed target. The next section explains why that number is never fixed.

Why the Cut Off Moves Every Year

The cut off moves every year because it is set by the strength of each year’s applicant pool, not by a fixed standard. When a particularly strong group of children sits the test, the cut off rises, and when the cohort is slightly less competitive, it can fall.

This follows directly from how selection works. Because the school fills a set number of places by ranking applicants from the highest TSS down, the final score that secures a place depends entirely on how everyone else performed. The bar is drawn wherever the places happen to run out.

Two forces push it around. The first is the number of applicants, which has tended to grow year on year as the program becomes better known, increasing competition for the same 225 places. The second is the calibre of the cohort, since a year with many exceptionally strong candidates lifts the score needed to make the final cut.

This is why fixating on a single number can mislead a family. A child aiming precisely at last year’s figure of 244 might find the bar has shifted by the time they sit the test. The cut off is a moving target, described after the fact, not a finish line set in advance.

The practical lesson is to aim comfortably above recent cut offs rather than exactly at them, and to focus on the things within your control. That naturally leads to the question every parent wants answered: what score does my child actually need.

What Perth Modern ASET Score Does Your Child Really Need?

To be competitive for Perth Modern, a child realistically needs a TSS in the mid 240s or higher, given recent cut offs, while comfortably clearing this band offers the safest margin. Because the cut off moves, aiming above it rather than at it is the sensible approach.

Put the bands in perspective. A TSS of 209.5 is the floor for any academic program consideration, and many GATE schools accept students across the roughly 210 to 244 range. Perth Modern sits at the very top of that spread, so a child needs to be performing not just well, but among the strongest candidates in the state.

That said, treat any specific number with care. Since the score is standardised against the whole cohort and the cut off shifts each year, no tutor or website can promise that a particular TSS will secure a place. The honest target is to rank among the top few per cent of applicants, and a strong margin above recent cut offs is the best protection against a competitive year.

It also helps to keep alternatives in view. The southern suburbs and wider Perth metro area are home to many excellent academic GATE schools with lower entry scores, so a child who falls just short of Perth Modern often has outstanding options closer to home in places such as Willetton, Rossmoyne or Applecross.

Knowing roughly what score is needed is useful, but it is not a plan. The real question is how to help your child reach that level, which comes down to what it genuinely takes.

How to Get into Perth Modern: What It Really Takes

Getting into Perth Modern really takes two things: genuine reasoning ability and consistent strength across all four ASET sections, built through steady preparation over time. Chasing a single number is the wrong focus. Building a well rounded, well prepared thinker is the right one.

The most important and least understood lever is consistency. Because the TSS adds four equally weighted standardised scores together, a child who is brilliant in three sections but weak in one loses far more ground than parents expect. A child who is strongly above average across all four will often outrank a spikier candidate, even without being the very best at anything.

This reframes how to prepare. Most families instinctively invest in a child’s strongest area, where progress feels rewarding, but the highest leverage work is usually lifting the weakest section. Identifying and strengthening that softest area is often what turns a near miss into an offer. Our breakdown of the ASET abstract reasoning section and the ASET writing task explained are good starting points if either is your child’s weaker area.

Time is the other essential ingredient. The ASET tests reasoning that develops gradually, not content that can be crammed, so the children who do best tend to have prepared steadily over many months. Wide reading, regular reasoning practice, and timed exposure to each section all compound slowly into real ability and calm confidence on the day.

This is where structured support can make a genuine difference. A tutoring centre experienced with the ASET can pinpoint exactly which section is holding a child back, build a balanced plan across all four, and keep the preparation consistent over the long runway the test rewards. For a child capable of Perth Modern, that focus on the weakest link and on steady, broad preparation is what it really takes. Our best study plans for Year 6 GATE preparation can help you build that runway early.

The Application Timeline and What to Expect

The Perth Modern application process follows a fixed annual timeline, and knowing it early helps families prepare without a last minute scramble. Everything hinges on a single application window and one test sitting, so missing a date can mean missing a year.

Applications open in October and close in early February, with the deadline for 2027 entry falling at 6pm on Friday 6 February 2026. Families apply through the Department of Education and nominate their preferred schools, including Perth Modern, on the one application.

The test follows in March. For 2027 entry, the metropolitan sitting is scheduled across the weekend of 7 and 8 March 2026, with regional centres such as Bunbury and Albany running a few days later, so families outside the city can sit locally without travelling to Perth.

Results and offers come mid year. Performance reports, which break down the four section scores and the TSS, are usually emailed in late May or early June, with first round offers following in late June. Perth Modern also holds information sessions and school tours around June for families who have received their scores.

It is worth knowing that a Year 9 entry round exists at some selective schools, offering a second pathway for students who narrowly miss Year 7 entry. Marking these dates on the calendar a year ahead gives your child the long, calm preparation runway that this competitive test genuinely requires.

Conclusion

Perth Modern entry comes down to one thing: a strong enough result in the ASET, expressed as a Total Standard Score out of 400. The cut off has hovered around 244 in recent years, but it is never fixed, because it is simply the score of the last child offered a place in a pool that grows more competitive over time.

That is why the smartest approach is not to chase a single number. The TSS rewards consistency across all four equally weighted sections, so the highest leverage preparation lifts your child’s weakest area rather than polishing their strongest. Combined with genuine reasoning ability and steady practice over many months, that balance is what truly opens the door.

Aim above recent cut offs, prepare broadly and early, and keep the wider GATE pathway in view, because Perth is rich with excellent selective schools beyond Perth Modern. Approach it this way and your child walks into the ASET prepared, balanced and confident, with the best possible chance of the place they are working toward, and strong options whatever the result.
