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).

(Nevertheless, if the FAQ did not answer your specific question, you may email

Classes are held weekly.

Class Meeting 1: Great Circles and Sect

You will begin this course by getting a firm grasp of the celestial circles, forming the important critical points necessary for chart construction and ultimately chart analysis. This knowledge introduces you to the metaphor of the East/West and North/South hemispheres of the chart. Simultaneously you will become acquainted with sect as it applies to nocturnal and diurnal charts.

This week contains supplemental video materials you’ll need to watch prior to class.

Class Meeting 2: The Historical Periods of Astrology and the Chart’s Hemispheres

This class requires you to read Chapter 2 in the NAT-1 e-Course Book before class. This chapter is essential and will give you a survey of the historical periods of astrology. This is most significant for your studies at IAA, because classical and modern astrology are taught side by side. It’s paramount that you understand history’s contribution to the astrological tradition.

In class, we will discuss the historical periods and define the difference between the classical (traditional) and modern astrological techniques and approaches.

Also, we will glean the meaning of the north, south, east and west hemispheres, determining hemisphere dominance in charts and what it means in delineation. The difference between the sect of the chart and the hemisphere emphasis will be evaluated.

Class Meeting 3: Quadrants & House Meanings

Having the background of the hemispheres, you can now identify the four quadrants of the chart. This segues into learning the significance of each of the twelve houses and also the types of houses: angular, succedent, and cadent.
This week contains supplemental video materials you’ll need to watch prior to class.

Class Meeting 4: Elements and Modalities, the 3/4 Rhythm of the Zodiac Signs

This week you will learn the depth of each of the signs and integrate their elements and the modalities. This unique overlay of the element and modality brings uniqueness to each sign.

Class Meeting 5: Archetypes I

In this lesson, you will get an introduction to the meaning of the archetypes and how they relate to astrology. Learning the archetypes that are associated with the planets and signs (and the mythology of the planets in NAT-2) will give you a foundation which will open astrology to your world, and your world to astrology.

Class Meeting 6: Archetypes II

You will continue with the in-class discussion of astrological archetypes.

Class Meeting 7: Modern Temperament Patterns

Marc Edmond Jones was one of the pioneers of modern astrology. He determined that the patterns the planets make in a chart are significant, and these patterns have been adopted by modern astrologers. You will explore these patterns.

Class Meeting 8: Classical Elements and Temperaments

In ancient Greece, transformation was associated with alchemy and to the ancient Greeks, alchemy was an everyday process. Making bread was alchemy; beer-making was alchemy; making bronze from copper and tin was alchemy. Aristotle was able to explain how things could change by applying the principle of being and becoming. In this class you will learn the principles and applications of the elements — air, fire, earth and water — and the temperaments: choleric, sanguine, phlegmatic and melancholic.

Class Meeting 9: Triplicity, Sect

In this class, we discuss the relationship between the elements and triplicity rulerships. Interpretation of triplicity in a chart will also be discussed.

Class Meeting 10: Essential Dignities: Rulership and Exile

In classical astrology, the four elements came to be embedded as one form of essential dignity, the triplicity.

The dignities were systems designed to highlight particular circumstances in which planets were said to have greater or lesser strength. You will learn how the affairs ruled by a particular planet may be easier or harder for you, or may simply become more prominent in your life.

Class Meeting 11: Other Classical Essential Dignities and Accidental Dignities

The essential dignities go back to the Babylonians. They discovered the hypsoma, the hidden places, what we call the exaltations. This class is solely associated with the essential dignities, that are of utmost significance in classical astrology. As well, you will receive the basic fundamentals of astrology.

Class Meeting 12: Delineation Practice, Review

Chart practice week! You will apply the techniques you’ve learned thus far using a classical chart and a modern chart to analyze. Several example charts will be used. The rest of this lesson will be dedicated to a review of the material and analysis of several example charts using the techniques you have learned during this course. At the end of the class, you will receive an examination assignment: a chart that has to be delineated using all the techniques learned. This is a take-home exam. You will have one week to complete it.
