Andreas Schleicher: Use data to build better schools | Video on TED.com

How can we measure what makes a school system work? Andreas Schleicher walks us through the PISA test, a global measurement that ranks countries against one another — then uses that same data to help schools improve. Watch to find out where your country stacks up, and learn the single factor that makes some systems outperform others.

What makes a great school system? To find out, Andreas Schleicher administers a test to compare student performance around the world.

Andreas Schleicher heads the Program for International Student Assessment (PISA) at the Organization for Economic Co-operation and Development (OECD). What it means is: He’s designed a test, given to hundreds of thousands of 15-year-olds around the world (the most recent covered almost 70 nations), that offers unprecedented insight into how well national education systems are preparing their students for adult life. As The Atlanticputs it, the PISA test « measured not students’ retention of facts, but their readiness for ‘knowledge worker’ jobs—their ability to think critically and solve real-world problems. »

The results of the PISA test, given every three years, are fed back to governments and schools so they can work on improving their ranking. And the data has inspired Schleicher to become a vocal advocate for the policy changes that, his research suggests, make for great schools.

« An outspoken critic of government policies that don’t prioritize education, Schleicher has been influential in translating hard data into real-world guidance for policy-makers. »
