Analysis of Australia's 2026 NAPLAN data puts the Year 9 numeracy gap at seven years and nine months

The 2026 NAPLAN national results, published by the Australian Curriculum, Assessment and Reporting Authority on 5 August 2026, describe a school system that barely moved on average and stayed sharply divided by parental background, remoteness and Indigenous status. About two out of three students reached the Strong or Exceeding proficiency levels in reading, numeracy and writing, and about one in ten sat at Needs additional support. In reading, the proportion at Strong or Exceeding fell to 66.3 per cent from 68.2 per cent in 2025, while the share needing additional support rose to 10.2 per cent from 9.3 per cent. In numeracy the equivalent figures were 67.0 per cent and 9.6 per cent. The tests were sat in March 2026 by more than 1.2 million students in more than 9,400 schools and campuses.

The subgroup figures in the same release are much wider than the year to year movements. Across all year groups, 23.1 per cent of students in very remote schools reached Strong or Exceeding in reading, compared with 70.0 per cent of students in major city schools. In numeracy the comparison was 23.1 per cent against 70.8 per cent. Around one in three Indigenous students, 31.8 per cent, sat at Needs additional support in reading, against 8.5 per cent of non-Indigenous students. In numeracy the figures were 32.4 per cent and 7.8 per cent.

ACARA's accompanying national results commentaries, dated July 2026 and released with the results, set out the parental background gaps year level by year level. In Year 3, the share of students at Developing or above was higher for children whose parents hold a bachelor degree or higher than for children whose parents left school at Year 11 or earlier by between 26.0 percentage points in writing and 38.6 percentage points in grammar and punctuation. In Year 9 the range was 22.1 points in spelling to 37.7 points in grammar and punctuation. Sorted by parental occupation instead, Year 9 students with parents in the senior managers and professionals group sat between 92.1 and 95.4 per cent at Developing or above, while students with parents in the unskilled manual, office and sales group sat between 71.5 and 85.3 per cent.

ACARA's chief executive, Stephen Gniel, said in the release that it was disheartening to see disparities persisting in the attainment of students from regional and remote areas, Indigenous students and those from a disadvantaged background, and that this needed to be a continuing focus.

On 12 August 2026, Andres Molina, a senior research fellow at Victoria University's Mitchell Institute, published an analysis in The Conversation converting NAPLAN scores into years and months of learning relative to average achievement. On his figures, the reading gap between children of parents who did not complete school and children of parents with a bachelor degree or higher widened between 2023 and 2026 from one year and ten months to two years and two months in Year 3, from four years and eleven months to five years and six months in Year 7, and from six years to six years and eight months in Year 9. In numeracy the Year 9 gap grew from six years and eight months to seven years and nine months, while the Year 5 gap narrowed from two years and ten months to two years and five months.

That reading is contested by the statistics ACARA itself publishes. The commentaries state that for Year 9, every one of 165 subgroup comparisons between 2025 and 2026 showed a negligible difference, and that 164 of 165 comparisons between 2023 and 2026 did the same. Writing in The Conversation on 5 August 2026, Sally Larsen of the University of New England argued that the movements are negligible on a scale running to 1,000 points, citing a 6.1 point rise in Year 5 numeracy, a 4.7 point fall in Year 3 numeracy and an 8.4 point fall in Year 5 reading, and that roughly 30 per cent of students fall into the bottom two proficiency bands every year. The two claims are not identical: Molina measures the distance between groups in learning terms, ACARA tests whether each group's own average shifted.

What the tests cannot settle is why the distance persists. Writing on 11 August 2026, John Frew argued that NAPLAN credits governments with gains and blames schools for failures, noting that New South Wales public schools remain below the Schooling Resource Standard until 2034, and that Australia has one of the largest gaps in staff shortages between advantaged and disadvantaged schools. Federal education minister Jason Clare pointed instead to numeracy improvements for Indigenous students of 9.5 points in Year 5 and 9.3 points in Year 7. The release records about 29,000 more students at Exceeding in numeracy than in 2023.

Several things remain unknown. Tasmanian state results were not reported at all, after industrial action in government schools pushed participation as low as 58.2 per cent in Year 3, and Northern Territory participation was cut by flooding. Indigenous participation nationally fell to 68.7 per cent in Year 9 numeracy, which leaves open how much of the reported gap is measured and how much is missing. A platform failure on 11 March 2026 forced a caveat on writing results for Years 5, 7 and 9. And no released figure yet shows whether the gaps closed or widened for the students who did not sit the tests.
