Selective School Score Calculator
School Assessment is based on Year 5 English and Mathematics results, weighted equally alongside the three test components.
Estimated score (illustrative only)
75.0%
This is a plain average of your four self-estimated component scores — Reading, Mathematical Reasoning, Thinking Skills and School Assessment, each weighted 25%. It is not the real selective test score: NSW Department of Education calculates the official result using statistical scaling and moderation that isn't publicly replicable, so treat this figure as illustrative only, not a prediction of your actual outcome.
Quick answer
This calculator estimates a NSW Selective High School Placement Test score by averaging four self-estimated component scores, each weighted 25 percent: Reading, Mathematical Reasoning, Thinking Skills and School Assessment. This is an illustrative estimate only, not the official, statistically scaled and moderated score NSW Department of Education actually calculates.

The NSW Selective High School Placement Test, used for Year 7 entry into a NSW selective high school, is made up of four components. According to NSW Department of Education’s own selective high schools information, Reading, Mathematical Reasoning and Thinking Skills each contribute 25% to a student’s placement score, and School Assessment — the student’s Year 5 results in English and Mathematics, as reported by their primary school — makes up the remaining 25%.
This calculator uses that documented 25/25/25/25 weighting to produce a simple illustrative average from four percentages you estimate yourself:
Estimated score = (Reading % + Mathematical Reasoning % + Thinking Skills % + School Assessment %) ÷ 4This is an estimate, not the official selective test score. The real placement score is not a plain average of raw percentages — NSW Department of Education applies statistical scaling and moderation to adjust marks for differences in difficulty between test versions and to compare each student’s performance against the wider cohort sitting the test that year. That scaling methodology isn’t published, so no calculator, including this one, can reproduce the exact official result. Use this tool only to get a feel for how the four components are weighted against each other, and treat the NSW Department of Education’s selective high schools page as the authoritative source on how placement actually works.
Worked example
Meera’s daughter Ananya is in Year 6 at a primary school in Epping, Sydney, and is preparing to sit the Selective High School Placement Test for Year 7 entry. After working through past papers and reviewing Ananya’s Year 5 school reports, Meera estimates Ananya’s likely performance across the four components as percentages:
| Component | Weight | Ananya’s self-estimated score |
|---|---|---|
| Reading | 25% | 78% |
| Mathematical Reasoning | 25% | 82% |
| Thinking Skills | 25% | 70% |
| School Assessment (Year 5 English & Maths) | 25% | 88% |
Entering these into the calculator gives a simple average:
(78% + 82% + 70% + 88%) ÷ 4 = 318% ÷ 4 = 79.5%
Meera now has an illustrative estimated score of 79.5% for Ananya. This number is not a prediction of Ananya’s real placement score — once NSW Department of Education applies statistical scaling and moderation and compares Ananya’s results against every other student sitting the test that year, the official score could land noticeably higher or lower than this simple average. Meera treats it as a rough sense-check of Ananya’s relative strengths across the four components, not as a placement forecast.
Frequently asked questions
How is the NSW Selective High School Placement Test actually scored?
The Selective High School Placement Test has four components that each contribute equally to a student's placement score: Reading, Mathematical Reasoning and Thinking Skills are each worth 25%, and School Assessment — based on the student's Year 5 English and Mathematics results — makes up the remaining 25%. This 25/25/25/25 structure is documented by NSW Department of Education, though the way raw marks convert into that final score involves statistical scaling that isn't published.
Does this calculator show my real selective test score?
No. This tool only averages four percentages you estimate yourself, weighted equally at 25% each. The real Selective High School Placement Test score is calculated by NSW Department of Education using statistical scaling and moderation — adjusting raw marks against how the whole testing cohort performed — and that exact methodology isn't published. Use this calculator for a rough, illustrative sense of the weighting only, and treat the NSW Department of Education's selective high schools page as the authority on how placement actually works.
What is 'School Assessment' in the selective test scoring model?
School Assessment is the 25% component based on a student's Year 5 results in English and Mathematics, as reported by their primary school. Like the three test components, it's moderated by NSW Department of Education before being combined into the overall placement score, rather than being used as a raw, unadjusted mark.
Why can't a calculator replicate the official scaled score exactly?
Because NSW Department of Education doesn't publish the statistical scaling and moderation formulas it uses. Scaling typically adjusts for differences in difficulty between test versions and compares each student's raw marks against the performance of the whole applicant cohort, information no public tool has access to. Any calculator that claims to reproduce the exact official score should be treated with caution.
Does a higher self-estimated percentage guarantee a higher real score?
No. Because the real score is scaled relative to how the entire cohort of test-takers performs in a given year, a raw percentage on its own doesn't map directly to a placement outcome. Two students who estimate the same percentage in a component could end up with different scaled marks depending on how difficult that year's test was and how other students performed.
Where can I find official information about NSW selective high schools?
NSW Department of Education's selective high schools and opportunity classes page is the authoritative source for test dates, the application process, and how placement actually works. This calculator is a general education tool and isn't affiliated with or endorsed by the Department.
