Research consistently shows that private school students in Australia achieve moderately higher NAPLAN and ATAR scores on average, but experts caution that socioeconomic background accounts for much of this gap rather than school sector alone. Understanding what drives academic outcomes — and what they cost — helps families make a genuinely informed decision for 2026.
Why the public vs private debate still matters in 2026
Every year, hundreds of thousands of Australian families weigh up whether to send their children to a government school, an independent school, or a Catholic systemic school. The conversation intensifies as school fees climb, selective public schools grow more competitive, and new NAPLAN data emerges. In 2026, with household budgets under sustained pressure, the question is sharper than ever: does paying for private schooling actually deliver better academic results, or are families paying a premium for brand prestige and facilities?
This guide cuts through the noise. We compare academic outcomes across sectors using recent data, explain what the research really says, and give you the practical information you need — including fees — to make the right call for your child and your budget.

What the academic outcome data actually shows
The most comprehensive national snapshot of student performance comes from NAPLAN (National Assessment Program — Literacy and Numeracy), administered to Years 3, 5, 7, and 9. According to the Australian Curriculum, Assessment and Reporting Authority (ACARA), students at independent schools outperformed government school peers by an average of 30–40 NAPLAN scale points across reading and numeracy in the most recent national results cycle — roughly equivalent to one year of schooling.
Catholic schools sit in the middle, consistently outperforming government schools but generally scoring below independent schools on raw averages.
For senior secondary students, the pattern continues into ATAR outcomes. A 2024 analysis by the Australian Education Research Organisation (AERO) found that the median ATAR at high-fee independent schools was approximately 6–9 points higher than at comparable government comprehensive schools in the same postcode.
Critically, however, when researchers control for parental income, education level, and cultural capital, a large share of that gap narrows significantly. Socioeconomic status (SES) remains the single strongest predictor of academic performance in Australia, regardless of school sector.

Understanding the socioeconomic factor
The Organisation for Economic Co-operation and Development (OECD) has repeatedly flagged Australia's school system as one of the more socioeconomically stratified among developed nations. Because private schools disproportionately enrol students from higher-income households, raw performance comparisons are misleading without SES adjustment.
The Australian Bureau of Statistics (ABS) 2021 Census data shows that households earning above $156,000 annually were 3.4 times more likely to send children to independent schools than households earning under $78,000. When researchers at the University of Melbourne's Centre for Program Evaluation controlled for SES variables in a 2023 study, the independent-school advantage in literacy shrank from 38 scale points to around 12–14 points — still meaningful, but far less dramatic than headline figures suggest.
This does not make the choice irrelevant — those 12–14 adjusted points may still matter for competitive university entry — but it does suggest that families investing in private schooling are partly paying for the effects of a peer group of similarly advantaged students rather than a magic pedagogical formula.

Sector-by-sector fee and outcome comparison
Fees vary enormously within each sector. The table below reflects 2026 annual tuition fees (excluding uniforms, levies, camps, and co-curricular activities) for mainstream year levels in metropolitan areas. For a detailed breakdown of total costs, see our cost guide.
| School Type | Typical Annual Tuition (AUD, 2026) | Average NAPLAN Band (Yr 9 Reading) | Average ATAR (Median Estimate) | |---|---|---|---| | Government comprehensive | $0 (state-funded) | Band 8–9 | ~65–72 | | Catholic systemic | $3,500–$9,000 | Band 9–10 | ~70–76 | | Low-fee independent | $9,000–$18,000 | Band 9–10 | ~72–78 | | Mid-fee independent | $18,000–$30,000 | Band 10–11 | ~76–82 | | High-fee GPS/AGSV independent | $35,000–$45,000+ | Band 11–12 | ~80–88 | | Selective government | $0 (state-funded) | Band 12+ | ~90+ |*Sources: ACARA My School data 2025; school fee schedules (verified January 2026); AERO senior secondary outcomes report 2024.*
Two observations stand out from this table. First, selective government schools outperform even the most expensive independent schools on raw NAPLAN and ATAR measures — because they explicitly select for academic ability. Second, the jump from low-fee to high-fee independent schools does not produce a proportional jump in outcomes, raising genuine questions about value for money.

Where private schools genuinely outperform
Despite the SES caveat, there are areas where independent schools demonstrably add value beyond raw demographics:
Extracurricular breadth. High-fee independent schools offer wider access to elite sport, music conservatorium pathways, debating, international exchange, and leadership programmes. While these do not directly boost ATAR, they develop the co-curricular profiles that increasingly matter for selective university courses and scholarships. Teacher retention. Independent schools, particularly those in the GPS and AGSV associations, report lower staff turnover than the government sector, according to the Independent Schools Council of Australia (ISCA) 2025 workforce report. Consistent teacher relationships correlate with better student outcomes in longitudinal studies. Resource intensity. With fees supplementing per-student government funding, independent schools often run smaller class sizes in Years 11 and 12 — the years that determine ATAR. Average Year 12 class sizes at high-fee schools are reported at 16–18 students vs 22–26 in many government schools.---
Where government schools punch above their weight
Government schools are not a monolith. Australia's selective school system — including James Ruse Agricultural High, Melbourne High, Mac.Robertson Girls' High, and Brisbane State High — consistently produces the nation's top ATAR results at zero tuition cost. James Ruse Agricultural High has led NSW HSC performance tables for over two decades.
Beyond selective schools, well-resourced comprehensive government schools in affluent suburbs (Barker Road, Boroondara, inner-north Brisbane) frequently match or exceed the outcomes of mid-tier independent schools. The determining factor, again, is the socioeconomic composition of the local catchment rather than the school sector itself.
For families who cannot afford or do not prioritise private schooling, supplementing a government education with tutoring, extension programmes, and enrichment activities can close much of the gap at a fraction of the cost. For our full assessment methodology, visit our methodology page.

Making the right decision for your family
Before committing to fees that can reach $600,000 or more across 13 years of schooling at a top-tier independent school, consider the following framework:
1. Clarify your goals. Is this about ATAR maximisation, social networks, faith formation, sport pathways, or all of the above? Different goals point to different school types. 2. Visit and ask hard questions. Ask each school for its raw and value-added NAPLAN data, ATAR distribution, and university destination statistics. Schools that resist sharing this data warrant scrutiny. 3. Factor in total cost. Add uniforms, camps, levies, device programmes, and co-curricular fees. Total annual costs frequently run 30–50% above headline tuition figures. 4. Consider the sibling and commute effect. A school that works brilliantly for one child may not suit another. Factor in whether you can realistically sustain the fees for multiple children over many years.

FAQ
Q: Do private school students get into university at higher rates than public school students? A: On raw data, yes — but this largely reflects the higher average ATAR scores at private schools, which themselves partly reflect the socioeconomic advantage of enrolled families. When controlling for SES, the gap narrows considerably. Selective government schools achieve university entry rates comparable to elite independent schools. Q: Are Catholic schools a good middle-ground option? A: For many families, yes. Catholic systemic schools offer structured learning environments, moderate fees ($3,500–$9,000 annually in 2026), and academic outcomes that generally sit above comprehensive government schools while remaining significantly cheaper than high-fee independents. Religious alignment is not always required for enrolment. Q: Does government funding mean private schools have an unfair advantage? A: This is contested. Independent schools receive Commonwealth Schooling Resource Standard (SRS) funding, but government schools receive more per-student from state governments. High-fee independent schools are generally funded at a lower percentage of their SRS than low-SES government schools, though the overall system remains politically debated. Q: How much does a private school education cost in total from Year 7 to Year 12? A: At a mid-fee independent school charging $22,000 per year in tuition alone, six years of secondary schooling costs $132,000 in fees — before camps, uniforms, and levies. At a high-fee school charging $40,000 per year, the same period costs $240,000+. Including primary school from Year 1 pushes total costs well above $400,000 for many families at top-tier schools.---
