John Chubb, a distinguished visiting fellow at the Hoover Institution, a member of Hoover’s Koret Task Force on K–12 Education, and interim CEO of Education Sector, has written The Best Teachers in the World: Why We Don’t Have Them and How We Could, which will be released on October 10, 2012. In the book, Chubb argues that student achievement in the United States could rise to levels comparable to the best nations in the world if we could improve teacher quality.
