We, the authors below, served on the Advanced Placement United States History Curriculum Development and Assessment Committee from 2008 through 2012. In that capacity, guided by continued dialogue with and input from the teachers who work each day with our nation’s most talented and dedicated students, we authored the Curriculum Framework that was published in October 2012 and that is at the heart of the College Board’s current Course and Exam Description for AP U.S. History.
