 Hi, I'm Rob Randall, Chief Executive Officer of Okara. Around a million students in Year 3, 5, 7 and 9 will participate in this year's NAPLAN. For some, this will be the last time they participate in a paper-based NAPLAN test because in two years' time we'll start rolling out NAPLAN online in schools across the country. This change will involve every school in Australia. Over the last few years, we've done a lot of research and trialling and track studies done overseas and there's more research to come before we take NAPLAN online in 2017. Let me recount what's been done so far. In 2012, we compared paper versus computer-based assessment, investigating the effect on student performance and student engagement. In 2013, we conducted research into the tailored test design. In simple terms, the tailored test design means that test difficulty is adjusted to students' achievement levels. We found that these tailored tests offered better measurements of student performance, particularly for high and low-achieving students. We also found that students were more engaged with online assessment. In 2013, we also delivered the National Assessment Program in Civics and Citizenship Online to over 11,000 Year 6 and Year 10 students. This allowed us to observe how students engaged with an online test delivery system as opposed to a paper-based testing environment. Last year, we conducted information and communication technology literacy sample assessment online and we'll conduct the sample science literacy assessment online later this year. As you can see, we've already been doing online assessment for several years now. Next year, in 2016, the central test platform being developed for NAPLAN Online will be used to deliver the National Assessment Program in Civics and Citizenship. And then, from 2017, we'll progressively move NAPLAN Online with everyone expected to be online in 2019. These are certainly exciting times for students, parents and educators alike.
