 We do courses, 30-hour courses for the high school teachers. And it meets after school and on some Saturdays. And the teachers can either receive P-credit, professional credit, towards their next salary differential, or they receive a stipend for their work. And of course they produce a product, which is a good thing. And in the second history in the classroom, we started sort of chronologically with our course. And it was Conflict, Continuity, and Change, which was right in the beginning. And the most recent course, which we're in right now, is the Civil War and Reconstruction. And actually the crisis of the Civil War and Reconstruction. And the way we do it is we hire usually an historian that is about to get his or her doctorate. So they're young.
