How to interpret
Results for both NAPLAN and NAP sample assessments tests are measured in similar ways. There are 2 important elements to how these results are reported: the scale and the performance standard that are used.
NAPLAN results are measured at a student level against an assessment scale in each of the areas tested. The scales span all the year levels from Year 3 to Year 9, and are divided into 10 bands. Not all bands are reported for each year level.
NAP sample assessment results are measured against a proficiency scale for each domain. The proficiency scales are grouped into a number of different levels.
More information about the scales used for NAPLAN and NAP sample assessments can be found at Scales.
For NAPLAN results, a national minimum standard is defined and located on the assessment scale for each year level. Band 2 is the minimum standard for Year 3, band 4 is the minimum standard for Year 5, band 5 is the minimum standard for Year 7 and band 6 is the minimum standard for Year 9. These standards represent increasingly challenging skills and require increasingly higher scores on the NAPLAN scale.
For NAP sample assessments, proficient standards represent a 'challenging but reasonable' level of performance where students need to demonstrate more than the minimal skills expected at that year level.
