After state leaders complained the course was “biased and inaccurate,” the Advanced Placement U.S. History course framework is changing. In January, Senate Resolution 80, sponsored by state Sen. William Ligon, R-Brunswick, demanded changes to the AP U.S. History framework created by the national College Board. The curriculum framework — or teaching guide for AP U.S. history teachers — was introduced last year and implemented for the first time during the 2014-15 school year.
