The American Federation of Astrologers takes pride in its examination and certification program, which has been in existence since 1960. It was designed - and continues to this day - to promote AFA's educational mission and the advancement of ethical astrology. Candidates are not limited to any one system of mathematics, house cusp division, or school of study. Each, however, must demonstrate a high level of accuracy in chart calculation and interpretation. AFA offers exams in natal astrology at three levels of proficiency: student, professional, and teacher. Each of these is a separate examination, and you must pass the student exam before taking the professional exam, and pass the professional exam before taking the teacher exam.
