NAPLAN standards have been revised upwards for this year, but about 65 per cent of students around the country are still meeting literacy and numeracy expectations.
Results are now graded “exceeding”, “strong”, “developing” and “needing additional support”.
About 23 per cent of students are “developing”.
Australian Curriculum, Assessment and Reporting Authority (ACARA) CEO David de Carvalho said participation rates had also increased, reversing a downward trend from recent years.
“This year’s NAPLAN results are the first to reflect the new reporting changes,” he said.

“They show strong performance among Australian students in literacy and numeracy skills, but also provide clear information on areas requiring improvement.”
The results showed girls outperformed boys in literacy in every year group, while boys generally achieved stronger results in numeracy.
But better results overall tended to go to students from higher socio-economic backgrounds and in urban areas.
The results also highlighted the education crisis facing Indigenous students.
While about 10 per cent of students nationally were in the “needs additional support” level, that rose to about 33 per cent for Indigenous students.
