It’s time to be honest with parents about NAPLAN: your child’s report is misleading, here’s how

At the national level, however, the story is different. What NAPLAN is good for, and indeed what it was originally designed for, is to provide a national snapshot of student ability, and conducting comparisons between different groups (for example, students with a language background other than English and students from English-speaking backgrounds) on a national level.

This is important data to have. It tells us where support and resources are needed in particular. But we could collect the data we need this by using a rigorous sampling method, where a smaller number of children are tested (a sample) rather than having every student in every school sit tests every few years. This a move that would be a lot more cost effective, both financially and in terms of other costs to our education system.
