Some of Brisbane’s most in-demand city high schools are boasting impressive progress results in national reading, writing and numeracy tests, with suburban state schools also making their mark.

Analysis of this year’s school-by-school NAPLAN results identified the select handful among Brisbane’s largest high schools that are outperforming their peers when it comes to boosting student achievement.

Among the top 20 largest high schools – which all have more than 1700 students – the reporting authority singled out two schools for exceptional performance: Brisbane’s third most-expensive private school Anglican Church Grammar School (Churchie), and Corinda State High School.

Corinda State High had an ICSEA (Index of Community Socio-Educational Advantage) percentile of 72, so the Australian Curriculum, Assessment and Reporting Authority (ACARA) compared it against other schools sitting almost at, or slightly above, the national average.

The year 9 cohort at Corinda State High made up about one-seventh of the school’s 2125 students this year.

From their year 7 performance, just over half of those students improved significantly, boosting the whole cohort’s performance from average in 2023, to above-average in 2025.

Churchie – a 1170-student school which runs from Prep to year 12 – achieved similar improvements in its year 9 cohort, improving students’ performance more than similar schools in about 60 per cent of students undertaking numeracy and writing tests.

Inner-city Catholic girls’ school All Hallows’ achieved the highest scores among the city’s 20 largest schools, with students achieving year 7 and 9 results “well above” averages at comparable schools.

The school was compared to other schools sitting in the 99th ICSEA percentile, which includes the most privileged schools across the state and nation.

ACARA chief executive Stephen Gniel said the data – released on Wednesday morning as the national schools directory website updated – gave parents and communities a yardstick for their children’s’ results through primary and middle school.

“With detailed information on every school in the country, ACARA’s My School [website] is the only website that publishes nationally consistent, school-level data that all Australians can see for free,” Gniel said.
