If you wish to receive college credit for taking an AP course, most colleges will require that the course have been approved by the College Board. Schools wishing to give their students AP credit must go through the AP audit process.

The same is true for homeschoolers. The AP Course Ledger section below gives more information about the audit process. The Ledger is an annual and culminating product of the AP Course Audit, a process by which college faculty confirm that courses submitted by AP teachers and schools provide students with the essential elements of a college level experience.

As an exclusively Web-based registry, the Ledger is published annually in November and updated weekly throughout the academic year to reflect newly authorized courses. Here is a link to AP Audit information, and you can find other links on this page to various other resources: Yes, the AP Course Audit is only required for schools desiring to: Schools that simply offer the AP Exam as an opportunity for their students to earn college credit, without actually labeling the school's courses "AP" on students' transcripts, do not need to participate in the AP Course Audit, and can continue offering AP Exams to their students.

In order to be authorized by the College Board and put in the AP Course Ledger, an instructor must submit a syllabus for the course. While we do not have instructors who teach our courses, we do have NROC member schools that teach the courses for credit and they have been approved through the AP College Board.
