National Progress Index (NPI)
Student Achievement Reporting

Measure and report on student achievements

Academic Assessment Services (AAS) has developed the National Progress Index (NPI) – a measurement scale, from zero to approximately one thousand, covering student achievement in Reading, Writing and Numeracy from Years 2 to 11 inclusive.

Monitor and track student achievements from year 2 to year 10

Student achievement is reported in three measures: Raw Scores; Stanines and NPIs. In addition to the NPI placing individual students, groups, classes and cohorts on a continuous measurement scale, schools have the option of importing their individual student NAPLAN scale scores into their AAS online reporting application. This function is particularly useful for those schools using AAS tests at Years 2, 4, 6, 8 and 10. It means that schools can have annualised student achievement scores at each and every year of their schooling from Years 2 to 10.


The example below shows data for a student who sat NAPLAN in Years 5, 7 and 9 and AAS tests in Years 8 and 10. For schools and parents, this style of reporting represents how a student has progressed over time and the value-add of their education.
