G.F. Brandenburg posted a graph from a recent report of the OECD–the same organization that sponsors the PISA tests–which shows the number of hours that teachers work in every country tested.

Teachers in the United States reported working an average of 46.2 hours a week, according to the Teaching and Learning International Survey, which was coordinated by the Organization for Economic Cooperation and Development and included responses from educators in 49 education systems. The global survey average was 38.3 hours a week. Only teachers in two other education systems—Japan and Kazakhstan—reported working more hours.

Of the hours U.S. teachers reported working, the bulk of that time—28 hours—is spent teaching, as opposed to on administrative work or professional development. That’s more than teachers in any other education system. The survey average was 20 hours spent teaching.
