Will I have to submit a new syllabus for the course audit?

No, there is no need to submit a new syllabus. If your course is currently authorized to use the AP designation, it will continue to be eligible for renewal by your school administrator. 

If you are submitting a syllabus for a new course in the 2023-24 school year: The syllabus development guide and sample syllabi have been revised to reflect the updates.
