How NAPLAN scores became proficiency levels
Until 2022, NAPLAN reported results on a 10-band numerical scale. Since 2023, every result is reported as one of four proficiency levels: Exceeding, Strong, Developing, or Needs additional support. The scale score still appears on the report, sitting on a common scale of roughly 0 to 1000 that runs from Year 3 to Year 9.
The line between Developing and Strong is the national minimum standard, and it is set higher for each year level. A score of 480 is a Strong result in Year 5 but only Developing in Year 9, because more is expected as students get older.
What the levels mean
Exceeding means performing well above the standard for the year level. Strong means at or above the standard, which is the on-track result. Developing means working towards the standard, and is a signal to focus on specific skills. Needs additional support means well below the standard, and usually means targeted help at school and home.
Use it as a starting point
NAPLAN is a snapshot, not a verdict. A result below Strong is diagnostic information, not a failure. The best next step is to find which specific skills are below standard and work on those. To see how this maps to the old bands, use the NAPLAN band calculator. Year 9 students in NSW should also read the Year 9 NAPLAN calculator for the HSC link.
