This is the most complete, philosophically rich and practical course on decumbiture and medical astrology techniques available to astrologers. Written by renowned expert J. Lee Lehman, PhD, the STA Medical Astrology Course offers a unique tutorial format, in which the principles of medical astrology are demonstrated through genuine client-charts and informative historical examples. Explanations of philosophical principles and traditional medical techniques lie at the heart of the study, but the method is also explored and demonstrated in detail. The course is highly practical and geared towards the consulting needs of modern astrologers whose clients live in a modern world, but who wish to understand their circumstances from a more holistic viewpoint.

It is not necessary for astrologers who wish to take this course to have previous experience in medical astrology. However, it is necessary to have good understanding of horary principles and technique. The STA Practitioners Level Horary Course is an excellent pre-requisite for this Advanced Practitioners Level Medical Astrology Course.

Lessons take the form of tutorials with follow-up discussion, chart examples and practical exercises. Throughout, students are taught how to extract meaningful details and sharpen their judgement, and each lesson allows the opportunity to consolidate what is taught through periods of practical application. The course is designed to offer knowledge of traditional doctrines in a balanced way, so that theoretical principles enlighten and facilitate (rather than overwhelm) the creative aspect of astrological interpretation.

The course includes a comprehensive set of reference notes, tips and instructions, with numerous example chart judgements, and resources that are unavailable elsewhere. It offers certification, so that by the end of the course any astrologer who is already capable of offering a professional astrology service will be appropriately prepared to explore health-related problems according to the traditional principles of astrology.


This advanced level astrology course offers the STA Practitioners Level Medical Astrology Course in an online format. Lectures and workshops are delivered weekly over a period of 16 weeks through a combination of supplied course notes, modern media presentations, and online tutorials (there is an additional study break around the middle of the course). Lessons are structured as tutorials followed by assignments with thought-provoking questions, and consolidation of principles through practical application of demonstrated technique. Students study at their own pace and within their own time, but always with supplementary group discussion and access to the tutor.

A typical session will include: a live presentation, reading, an individual assignment (e.g., chart examples or workbook activities) and an assignment which encourages group interaction (e.g., forum discussion). Each week Lee will guide that week's course content, review student assignments, give personalized feedback and be available for questions and guidance.

Students receive their own set of personalised course notes which includes explanations of key principles, workbook-style activities, example medical astrology charts and answer sheets. This student workbook will also be cross-referenced with Lee Lehman's book, Traditional Medical Astrology, which acts as an accompanying text-book for the course.

Please read the policies, requirements and recommendations (below) before making an enrolment.

Policies, Requirements and Recommendations

  • Students on this course do not need to have previous experience in medical astrology. However, this course specialises in advanced-level astrological training so it is necessary for participants to have a firm understanding of all basic astrological principles, and to have already studied certain principles that are generally taught as part of the study of horary astrology. For that reason, we recommend students to have previously undertaken the STA Practitioners Level Horary Course.
  • This is an English language delivery of the course so it essential that students have a fluent understanding of the English language.
  • Chart calculation is not taught as part of this syllabus, except for techniques specific to medical astrology (such as the calculation of temperaments, critical periods, etc). Participants are expected to be competently able to draw up and interpret astrological charts using basic natal techniques.
  • The course materials should be accessible on all modern computers. It is assumed that students have access to a printer, and it is necessary to have stable internet access, as all coursework is done online through the STA Course Portal. Students are required to download a free video conference program, Zoom, to enable interactive online sessions with the tutors and fellow students.
  • Students should regularly commit to the course and expect to spend between 4 to 8 hours per week to comfortably make it through all the course material and the associated exercises. The qualifying certificate is only issued to students who demonstrate their study and understanding of the material by successfully completing the set assignments.
  • Tuition materials are provided in a serialised form throughout the course, as PDF downloads. All materials used in the delivery of this course are strictly copyrighted and provided for personal study only – no element of them whatsoever can be reproduced or recirculated in any form. Video tutorials are not available for personal download and can only be accessed by logging in to the secure course portal. Graduates are allowed continued access to these videos and any other resources on the course portal for 12 months subsequent to the formal completion of the course, but tutorial support ceases two weeks after the formal completion of the course.
  • Places held by a deposit must be paid in full before the agreed deadline. If the full payment is not completed by the advertised deadline we reserve the right to offer the placement to someone else. In the unlikely event that the course is cancelled or postponed, STA will refund all course fees but will not be liable for any other additional costs personally incurred by participants.
  • If a student pays for the course and then changes his or her mind for any reason, a cancellation will be arranged and the refund of any payment is provided within 30 days of that payment. No refunds are allowed after this 30-day period or after the delivery of any formal course material has commenced. This is due to the fact that places on our courses are strictly limited and once a course is full we prevent further enrolments: therefore deposits paid to secure and hold a registration are non-refundable and non-transferable after the 30 day ‘cooling off’ period has expired.
