School principals can make a big impact. A highly effective principal can raise student achievement by up to seven months a year for a typical student, and even more for a disadvantaged student. But running a school well is a difficult job-just ask any principal. Schools are complex organisations. The average secondary school principal manages a budget of more than $15 million, which is more than the turnover of 98 per cent of Australian businesses. And Australia expects each one of its schools to provide an excellent education for every child. But governments have radically underestimated how hard this is for schools to achieve. The result is that schools often feel poorly supported in their work. Our latest education report, Spreading success: Why Australia should trial multi-school organisations, delves into the question of how we best support schools to improve. This podcast discusses the new report with authors Jordana Hunter, Amy Haywood, and Nick Parkinson.
