The Halifax Astrology School offers courses on all hand-calculations required to achieve any of the US exams, including NCGR, and ISAR.

A basic level of rectification is a requirement for graduation from any Halifax Astrology School Diploma. You must be able to demonstrate that you are able to tell when the person's reported time calculates to a rising sign that does not match that person's physiology and or life events.
Advanced Rectification Certification is also available. This is for those professionals who choose to specialize as rectifying Astrologers.
