Our kids school puts no effort into it, they also happily tell us all we can be exempt. Apparently 4 in a class might do it?
I would also like to think the parents of my children's peers wouldn't rely on myschool to decide where their kid will attend school.
The effectiveness of a school cannot be measured by comparative testing like NAPLAN.
I don't like comparative testing in general, I want to know where my child needs extra work, but not how they compare to their peers.
