She used the US example to justify Australia-wide testing in literacy and numeracy at years 3, 5, 7 and 9 and making school results public on the My School website. In 2008 Gillard met Klein in New York and was so impressed with his policies that she invited him to Australia to show his approach of publicly ranking schools and penalising the underperformers.
