EPI's weekly illustration of education data trends — August 6, 2014
Internationally, postsecondary education is divided into two basic categories: Tertiary A and Tertiary B. The former is more akin to us four-year institutions, and the latter more to our two-year institutions. There is variance in the types of systems and programs across each country, so this isn't a completely solid interpretation.
Canada leads all OECD nations with a 52 percent of adults of ages 25-64 in tertiary completion, followed by Japan (46), Israel (45), and the United States (41). The OECD average is 32 percent.
