Welcome to the STA homepage

Our upcoming courses:


The School of Traditional Astrology (STA) places its educational focus on the integration of traditional astrological principles within contemporary astrological practice.

Founded by Deborah Houlding, the school offers practitioner's level accreditation in horary through attendance at classes, residential intensives or interactive online courses. Since 1996 courses have been delivered at venues as far afield as Australia, Bali, Canada, England, France, Hawaii, Hong Kong, Ireland, Netherlands, Norway, New Zealand, Scotland, Tasmania and the USA. The course is available to Chinese, Dutch, and English language students.

The school also offers advanced master's level accreditation for astrologers wishing to teach horary, through a four-year correspondence course which is studied on a one-to-one basis with a dedicated horary expert. This leads to the astrological qualification: STA DipH.

The school also offers a program of courses written by J. Lee Lehman, PhD which specialise in the traditional principles of Medical Astrology. The Practitioners Level Medical Astrology Course is now available as an intensive attendance course or an interactive online study course. This course introduces the natural philosophy which enlivened the historical development of Hippocratic and Galenic medicine and explores the logic of traditional therapeutic methodologies to show how astrological systems were used for the analysis and timing of critical procedures.

The STA Masters Level Medical Astrology Course is a top-level study course designed for astrologers who want to gain expert, specialist understanding of Medical Astrology practice. Delving deep into the primary sources, it explores a combination of ideas from modern practitioners of the Arabic tradition of medicine (with cutting edge ideas in herbalism), and other alternative systems of medicine to address the astrological considerations behind such issues as the similars-antipathy debate, the astrological considerations of purges and cleanses, and the mechanisms of tolerance and addiction.

New courses, which offer specialist training in other branches of classical astrological technique, are currently in development and will be added to our syllabus in 2020.

The aim of the STA is to:

  • facilitate greater understanding and respect for the philosophy and practice of astrology
  • ensure the historical transmission of astrology as a line of continuation between past, present and future practitioners
  • support the development of astrology practitioners to their full potential
  • 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
  • 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


The School of Traditional Astrology is a full member of the Advisory Panel on Astrological Education (APAE).
STA courses are endorsed by the APAE and approved by the Association of Professional Astrologers International (APAI).
