All Advanced Placement (AP) courses are run by the College Board which requires all AP courses to teach specific material. For each AP course, the College Board releases a course description booklet that holds the requirements that all AP teachers must teach in their classes. The course description booklet is referred to as the CED and all CEDs are publically available for everyone online.

​

Because all AP courses are run through the College Board, these courses take a long time to be updated and reviewed. As of 2022, the last revamping of the AP United States History (APUSH) CED was done in 2020. Because the CEDs are written by a group of experienced and seasoned teachers, many of the editors of the curriculum do not know many things about the history of the LGBTQ+ community which leaves them to often be left out. In the current edition of the APUSH CED, there is no mention of queer people anywhere in the curriculum, meaning that the College Board does not require teachers to teach their students an accurate version of history, one that includes members of the LGBTQ+ community.
