About the STA

The School of Traditional Astrology places its focus on tried and tested astrological techniques that are based on profound metaphysical principles and which have proven their worth over centuries of successful practical application.

Founded by Deborah Houlding in 1996, and initially specialising only in horary astrology, the school is now the collaborative product of some of the world's finest astrologers working together to create an expanding syllabus of courses. Currently, the STA offers training in horary astrology (in English, Chinese and Greek) and medical astrology: new courses on electional astrology and astronomy for astrologers are scheduled for release in 2022.

The STA does not currently offer courses suitable for beginners.

Horary Astrology

Horary astrology is not an obscure, historical astrological technique that defines the interest of an astrologer – it is a fundamentally important, key component of all the integrated branches of modern-day professional astrological practice. Every consulting astrologer should have a good understanding of horary, and know when it is the best technique to employ for clients.

The STA horary program is totally unique in its structure and content. Based on decades of in-depth research by Deborah Houlding, the finer points of horary practice are explored through to their symbolic origins, to remove all areas where potentially confusing concepts could cause uncertainty in practice.

Practitioners Level
Horary Certificate

This intensive 5-month course is suitable for astrologers who already have a firm grasp of basic astrological interpretation. It offers our core program of horary instruction, which demonstrates the most efficient and meaningful way to approach horary interpretation. The course also explores the philosophical, astronomical and metaphysical roots of traditional astrological symbolism in considerable depth, in order to ensure the employment of those principles in horary is as competent and confident as possible. The course offers a practitioner level qualification in horary, and also acts as a foundational program: graduates of this course are able to progress to advanced level assessment and tuition (if desired), and are sufficiently prepared to gain expertise in other astrological branches that rely on good understanding of traditional technique.

Advanced Level
Horary Diploma

Graduates of the Practitioners Level Horary Course are eligible to apply for the Advanced Level Horary Diploma. This self-paced mentorship program offers tutorial support that bridges the gap between understanding theory and gaining confidence in professional practice. Qualification requires the submission of three seperate horary case studies. These are analysed and critically assessed, with focus applied to helping improve the flow of chart interpretation. Points of judgement and details of professional practice are explored through discussion, always within the context of the astrologer’s personal chart judgement under examination. Graduates are entitled to advertise their fulfilment of our assessment criteria by using the initials STA DipH (School of Traditional Astrology Diploma in Horary) in promoting their astrological services.

Medical Astrology

Why would anyone want to study an archaic system of medicine with astrology attached to it? The answer is simple: these systems originate appreciation of the body as the nexus of body, mind, and spirit; where healing occurs through the creative balancing of all three with the environment.

The STA Medical Program is designed to teach how this system worked, and how astrology is used within it: whether to analyze the course of disease through an event or horary chart, or to time procedures such as surgery or administration of drugs and herbs, or to study of the development of imbalances within the body as shown by the nativity and its dynamics. Written by expert medical astrologer and trained botanist J. Lee Lehman, this program teaches how a practitioner of the 17th century (and earlier) would have viewed both wellness and disease, and how the concept of imbalance underpins much of the traditional understanding, and treatment, of illness.

Practitioners Level

This 20-lecture course is suitable for astrologers who have graduated from the STA Practitioners Level Horary Course, or are confident that they already have a firm grasp of traditional astrological principles. It introduces the natural philosophy which enlivened the historical development of Hippocratic and Galenic medicine, and the logic of the many therapeutic methodologies that developed in the ancient world, along with their astrological systems for analysis and timing of critical procedures.

If you have ever used herbal preparations, you have used components of this system, perhaps without even realising. Knowledge of the framework – which largely lies within the combination of planetary rulerships and the understanding of the elements – can help make better decisions about the use of herbs, whether through extracts, flower essences, or essential oils. It will deepen the understanding of medical horaries that was developed in the STA Horary Practitioners Horary Course. Students will begin to be able to identify potential future disease indicators in the nativity, as well as providing a system for designing wellness lifestyle decisions which address future patterns.

Masters Level

The STA Masters Level Medical Astrology Course is an advanced, part-time study course, offered only through direct correspondence with J. Lee Lehman, PhD. A 'hands-on' course, it uses primary sources and extensive chart work to fortify understanding of the concepts presented in the Practitioners Level Medical Astrology Course. The course is designed for astrologers who are willing to explore traditional methods and philosophical implications of classical medical astrology in depth, and who wish to gain sufficient mastery of all its complex concepts to be confident of communicating its theory and practice to other astrologers. This includes the clear understanding that medical astrology is a timing system, not a means of medical diagnosis or treatment, which are the purview of licensed medical professionals.

The overall aim of the course is to guide the student towards acquiring and demonstrating the ability to research selected fields of inquiry; to draw appropriate references to support relevant arguments; to gain detailed knowledge of medical and traditional astrological principles; and to demonstrate clear understanding of the historical, social and philosophical influences that have been impressed upon the astro-medical art.

STA Aims

To facilitate greater understanding and respect for the philosophy and practice of astrology.

To ensure the historical transmission of astrology as a line of continuation between past, present and future practitioners.

To support the development of astrology practitioners to their full potential.

To promote awareness of the need for every consulting astrologer to have a confident knowledge of horary, together with a good understanding of when it is the best technique to use, and when and how a horary chart can be used in combination with other relevant charts.

To provide “chart-led” instuction on classical astrological techniques, which not only explains the theoretical and philosophical principles, but recognises that the purpose is to generate confidence in the art of chart judgement in modern-day astrological practice.
