These tables, based on raw NAPLAN scores, were always an imperfect measure of performance. Small sample sizes, and the varying abilities of different years' students, meant schools jumped wildly up and down the tables from year to year.

This year, we're trying something a little different. We've ranked schools by how well the same group of students improved their results over two years (from 2013 to 2015). It's still imperfect, but we feel it's a more useful representation of the work schools do.
