An education specialist says schools should tell parents the extent to which their children are achieving the new national standards.
Schools are required to report children's performance against standards in reading, writing and maths for the first time this year.
But how they do that is up to each school.
Otago University's educational assessment research unit says schools should tell parents more than just whether a child is below or above the level set for their class.
Co-director Professor Terry Crooks says schools should say exactly which standard the child has reached, which will give an idea of their progress.
