"Our statistical model," he told me when we met at the OECD's headquarters in Paris, "accounts for 85% of the performance variation between schools in the countries we study." He recently started a series of reports on individual countries, issues frequent bulletins on what works and what doesn't ("the disciplinary climate in schools is strongly related to student performance," he states sternly but unsurprisingly) and plans next year to offer schools a test that allows them to measure themselves against others across the world. His catchphrase, displayed in a continuously rolling ticker as he ends his lectures, is "without data, you are just another person with an opinion".
