The Foundations course is to be taken first. After that, the courses can be taken in any order depending on specific student needs and goals.
For example, students with a strong theology background may take the ACBC Exam prep course right after Foundations, and then take the other courses as they work on the 50 supervised counseling sessions with an ACBC Fellow. If ACBC certification is not the goal, then any courses can be taken after Foundations.
