Closing the achievement gap between Indigenous and non-Indigenous students is a critical policy focus in Australia. Simple analyses of the Australian National Assessment Program—Literacy and Numeracy (NAPLAN) data have shown that while some improvement in the performance of Indigenous students is occurring, the gap is still considerable. However, relatively little research has explored these data to answer complex questions. This presentation presents multilevel analyses of linked data on pupil achievement for a single cohort from Year 3 to Year 5 in Numeracy in Queensland, Australia, to explore Indigenous and non-Indigenous progress and variables affecting achievement. Results show the complexity of interactions in student achievement and the significance of prior achievement regardless of student background. Further, the importance of adjusting for measurement error in test scores to identify student patterns of performance is illustrated. The findings demonstrate that more appropriate statistical analyses can yield different implications for education policy. The importance of properly adjusting for missing data values will be illustrated.
