Our AP content is a good resource to help students prepare for AP exams. However, while we provide content resources, we do not have instructors who teach the courses. 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. *AP, Advanced Placement and Advanced Placement Program are registered trademarks of the College Board, which was not involved in the production of, and does not endorse, this content.
The advocates of “open source software” tried to make it a trademark, saying this would enable them to prevent misuse. This initiative was later dropped, the term being too descriptive to qualify as a trademark; thus, the legal status of “open source” is the same as that of “free software”: there is no legal constraint on using it. I have heard reports of a number of companies' calling software packages “open source” even though they did not fit the official definition; I have observed some instances myself.
