What Is the 4% Rule for Victoria's Selective Entry High Schools?
If your child is preparing for the Melbourne Selective Entry High School exam, you may have heard parents and students talk about the 4% rule. It can affect offers, particularly when several strong candidates come from the same Year 8 school.
The rule is often misunderstood. It does not mean that 4% of every school automatically gets into a selective school. It is a cap on certain offers from a student's current school.
The 4% rule in simple terms
For most secondary schools, no more than 4% of the school's Year 8 students can receive standard merit and principal discretion offers to Victoria's Selective Entry High Schools. The percentage is based on the Year 8 cohort at the student's source school, rather than the number of students from that school who sit the exam.
What is a "source school"?
Your source school is the school you attend in Year 8, when you sit the entrance examination for Year 9 selective entry.
This matters because the Selective Entry 4% rule is linked to the size of that school's Year 8 cohort.
Why does Victoria have a 4% rule?
The Victorian Department of Education says the source-school cap is intended to reduce the impact that selective entry admissions can have on individual schools.
Without a cap, a school with a large number of very strong applicants could potentially lose a sizeable group of its Year 8 students at the same time.
Victoria currently has four Selective Entry High Schools for the central Year 9 entry process:
Boys' selective entry school in South Yarra.
Girls' selective entry school in Melbourne.
Co-educational selective entry school in Berwick.
Co-educational selective entry school in Werribee.
Does the 4% rule apply to every type of offer?
No. This distinction is important.
Standard Merit
Around 85% of places are offered through standard merit based on exam rank. These offers are subject to the source-school cap.
Equity Consideration
Up to 10% of places can be offered through equity consideration. These offers are not subject to the 4% source-school cap.
Principal Discretion
Up to 5% of places can be offered through principal discretion. These offers are subject to the source-school cap.
Because equity consideration is outside the cap, the total number of students receiving offers from a particular school can sometimes be higher than 4%.
What if your child attends a very competitive school?
This is where the 4% rule for selective entry attracts the most attention.
Imagine a school where many Year 8 students sit the selective entry exam and several perform very strongly. Once the source-school cap becomes relevant, students are also competing within a particularly strong group from their own school.
This can mean that a student with a strong exam performance may still miss a standard offer if enough higher-ranked students from the same source school are ahead of them.
Discussions among Victorian students online show that this is one of the main concerns around the rule. Students regularly ask whether attending a competitive school lowers their chance, whether 4% is guaranteed, and what happens when only a few students from their school sit the exam.
A 4% cap does not mean a 4% guarantee
This is probably the most common misunderstanding.
If your school's Year 8 cohort allows up to four students under the cap, the selective schools are not required to offer four places to students from that school. Students still need to perform strongly enough in the entrance examination and qualify through the selection process.
What about Prep to Year 9 schools?
The current Victorian policy has a different cap for schools that operate from Prep to Year 9. For these schools, the source-school cap is 10% rather than 4%.
Home-schooled students and students attending interstate or overseas schools are treated as separate cohorts for the purpose of the source-school cap.
So what should students actually focus on?
Do not let the 4% rule become the preparation strategy.
A student cannot control the size of their Year 8 cohort, how many classmates apply, how those classmates perform, or whether the source-school cap eventually affects an offer.
They can control how well they prepare, how accurately they answer questions, how they manage time and how confidently they approach the examination.
In our view, this is the healthier way to approach the Victorian selective entry 4% rule. Understand what the rule means, then put it aside and concentrate on improving the things that can actually change your exam performance.
Prepare for what you can control
Timed practice can help students become familiar with selective entry question styles, work on weak areas and improve their approach under exam conditions.
