History Underground is a grassroots movement started by two US History teachers in Spartanburg, South Carolina. With over 20+ years of experience between them, they've perfected the art of preparing their students for the End of Course exam in US History. The mission of History Underground is to transform the way that high school students prepare for the US History EOC. Our goal is not only to prepare them for the test, but to present pertinent information in a way that sticks with them long after they leave your US History classroom. Whether you're a first year teacher, or a veteran looking for new ideas, our teacher guides and student workbooks provide US History EOC prep like you've never seen before.
