NAT-1: Foundations in Astrology

This is not a beginner’s course! Before you enroll in this course, you need to know:

  • The planets and their glyphs
  • The signs and their glyphs
  • The planetary rulerships of each sign

The above are the minimum requirements necessary for enrollment in NAT-1.

When you enroll in NAT-1 you have realized astrology’s complexities and want to get them right. You are at the point in your study where you are ready to jump into a structured learning environment and delve into a systematic study of astrology.

We know you have questions. We have attempted to answer all of your questions in the Professional Training Department’s Frequently Asked Questions (FAQ).
