Understanding NAPLAN
How NAPLAN works, what the four proficiency levels mean, and how to read your child's report in the context of school-wide trends.
Every year I hear versions of the same conversation. A parent will mention their child's NAPLAN results with a kind of forced brightness — "she got Strong in reading, which is apparently good?" — that tells you everything about how well we communicate what NAPLAN actually means. This guide aims to change that.
What NAPLAN is
NAPLAN — the National Assessment Program: Literacy and Numeracy — is a standardised national assessment administered to all Australian students in Years 3, 5, 7, and 9. Since 2023, it has been delivered as an online adaptive test: the questions adjust in difficulty as a student responds, producing a more precise measurement across a wider ability range than the old fixed-paper format allowed.
The test covers four domains: reading, writing, language conventions (spelling, grammar, punctuation), and numeracy. Each domain is assessed separately, and results are reported separately.
The four proficiency levels — explained plainly
Exceeding means the student is performing above the challenging national standard for their year level. If your Year 5 child is at Exceeding in reading, they are doing better than a significant majority of Year 5 students nationally and are likely working comfortably above what the standard Year 5 reading program demands.
Strong means the student is meeting the challenging national standard for their year level. This is where most families want their child to be — it means they are performing as expected by a rigorous national benchmark. Strong is a good result.
Developing means the student is working towards the expected standard but has not yet reached it. This is not cause for alarm — many students are "Developing" in one or two domains at any given NAPLAN sitting. It is a signal to monitor and, if it's consistent across years, to address.
Needs Additional Support means the student is not yet demonstrating the foundational literacy or numeracy skills expected at this point in their schooling. This used to be called "below national minimum standard" — the name change is deliberate, to frame it as a call to action rather than a label. If your child receives this result in any domain, it deserves immediate attention: speak to the class teacher and ask specifically what support is being provided and what you can do at home.
Reading a school-level NAPLAN result
School NAPLAN profiles on ACARA's My School (and on WhatSchool) show the distribution of students across all four proficiency levels for each domain. A few rules for reading these well:
- Always compare schools with similar ICSEA scores. Never compare a school with ICSEA 1100 and one with ICSEA 950 on raw NAPLAN data — you're largely comparing community profiles.
- Look at multiple years. One year's result can be unusual — a small cohort, an unusual student mix, a disrupted year. Three to five years of data gives you a trend.
- Look at the bottom, not just the top. The percentage in Needs Additional Support tells you about a school's commitment to — and success with — its most vulnerable learners. A school that excels at the top but struggles at the bottom has a culture worth investigating.
- Small cohorts = less reliable data. If a year level has under 20 students, statistical variation is high. Year-on-year swings of 15–20 percentage points can be normal noise, not signal.
What to do with your child's individual result
Read it with curiosity, not anxiety. Then ask two questions: Does this match what their teacher sees day-to-day? And if it doesn't — if the result is surprisingly low or surprisingly high relative to their classroom performance — why might that be?
The individual NAPLAN result is most useful as the starting point for a conversation with your child's teacher, not as a final assessment of where your child stands.
