An education expert has dismissed Treasury's call to rethink classroom sizes so more money can be pumped into improving teacher quality, saying New Zealand teachers are already among the highest performers in the OECD.
Treasury Secretary Gabriel Makhlouf last week said modest increases in class sizes, of about one or two students per class, would allow some government education spending to be redirected towards boosting teacher performance.
"We think redirecting that expenditure towards strengthening the teaching profession and supporting the better use of data would deliver better bang for our buck in improving student achievement," he said.
But a Massey University education expert today said that ignored "hard data" showing the quality of New Zealand teachers was already higher than the OECD average, despite lower spending per student.
Professor John O'Neill of the College of Education said a 2009 report found New Zealand students ranked fourth out of the 34 OECD countries in reading, fourth in science and sixth in maths.
