 So, NAPPLAN is a large-scale, our standardised testing program. It stands for National Assessment Program, Literacy and Numeracy. So it was introduced in 2008 by a Labour Government as a way to sort of improve accountability goals for the country and also to improve transparency around data so that parents could better understand what was going on in schools. NAPPLAN has been quite controversial right from the outset. People have been highly interested in what is its purpose and value and what we found is that that has not actually been clearly communicated. So there's still some work to be done in terms of clarifying the goals and the aims of NAPPLAN as it starts to move into an online space. I think parents really need to have a stronger voice in this conversation and they are concerned about their children and how NAPPLAN makes them feel so they're trying to outweigh the benefits and costs as well to see if it's worth continuing. Parents do get one printed report each year that compares their child to the national average but of course for some children that can be highly distressing if they're in a low SES school and their results are far lower than the national average. So we're also arguing that the way the results are presented to parents is not very clear and parents can have some difficulty interpreting what it actually means. We have seen that a lot of think tanks had done research on NAPPLAN and there been a lot written about it and we wanted to take a very neutral standpoint to really balance the different debates. And I guess the main finding we have was that we found out NAPPLAN is not doing very well as a communication device. So people are still very confused about its purpose and its value and what it's actually doing for students, teachers, parents and schools. NAPPLAN is just one test on one day in a year so it's just a snapshot in time. It's not a whole portfolio of student performance over a year but I certainly would encourage parents to speak to their teachers, to speak to principals and to ask questions about NAPPLAN and to also read widely as it starts to undergo these transformative changes.
