Horary acts as an entry to many branches of astrology, and this comprehensive course will challenge, stretch and greatly enrich your understanding of astrological philosophy and symbolism generally, as well as horary specifically.

Benefitting from over 25 years development, in-depth research and continued investment into improved delivery methods, the STA’s Practitioners Level Horary Course has gained an outstanding reputation for the uniqueness of its syllabus and the ease with which it clarifies fundamentally important astrological principles which are seldom explained elsewhere.

Although traditional techniques lie at the heart of the study, the course is fully focused on the consulting needs of the modern astrologer, with the aim that everyone who completes this course will gain confidence and competence in this enormously valuable branch of judicial astrology.


The format of this course has been developed to maximise the advantages of online delivery. Twenty session themes are delivered on a weekly basis, through a combination of supplied course notes, modern media presentations, online tutorials and set assignments. Each student studies at their own pace and in their own time, but always with easy access to guidance and support from the tutors, and with the benefit of supplementary study-group discussion.

A typical session will include: a live presentation (attendance is optional: this is recorded and can be watched or reviewed later); a reading and self-study assignment; workbook activities or additional example charts to aid preparation for the session assignment; an online assignment which tests understanding of the session’s main principles, and an 'Answer Key' document which provides extra follow up material and more information on points discovered through taking the assignment. The tutors deliver and guide the week's content, review student assignments, give personalized feedback and are always readily available for questions and feedback. We also encourage students to engage in group interaction through forum discussion, and through some of the extra chart discussion sessions that we host within the course.

Policies, Requirements and Recommendations

  • Whilst previous experience of horary is not required, this course is unsuitable for students who are inexperienced in casting charts or just beginning to gain an understanding of astrology. Participants must have a good understanding of general astrological principles, including an easy familiarity with the symbolic and theoretical principles of astrological planets, signs, houses, aspects and transits. (For more on this, see the last point below).
  • The English language delivery of this course has over 400 A4 pages of accompanying course notes and approximately 40 hours of live/recorded tutorials. The tutors are American, Australian and British (with accompanying accents) so it essential that students have a fluent understanding of the English language.
  • Students should expect to regularly commit approximately 6-8 hours per week to the study of this course. Our qualifying certificate is only issued to students who demonstrate their study and understanding of the material by successfully completing our set assignments. Students who fail to do this within two weeks of the completion of the course are allowed a 6-month period to revise or catch up with any missing assignments. These will only be graded once all are complete for an additional cost of £75 (no personal tuition or feedback is provided for students seeking to complete or resit assignments beyond two weeks of the formal course completion).
  • Course materials are provided in a serialised form throughout the course, as PDF downloads. Our Textbook, Workbook, Answer Keys and all materials used in the delivery of our course are strictly copyrighted and provided for personal study only – no element of them whatsoever can be reproduced or recirculated in any form. Our video tutorials are not available for personal download and can only be accessed by logging in to our secure course portal. We allow graduates 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 we do not continue to provide tutorial support, which ceases two weeks after the formal completion of the course.
  • The course materials are 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.
  • In the two weeks prior to course commencement, registered students are required to watch a 30 minute introductory video which demonstrates how to navigate through our course portal, access materials and submit assignments.
  • 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.
  • Chart calculation is not taught as part of this syllabus, except for techniques that are specific to horary astrology (such as planetary hours and the calculation of planetary dignity scores, etc). Participants are expected to have previous experience of drawing up and interpreting astrological charts. See the chart below for an example of the format applied to study charts throughout the course. Applicants should be able to see, just by looking at the chart, that the Moon is separating from a trine with the Sun and applying to a square with Mars, and that the Moon is placed within 1° of the 9th house cusp. It should also be understood that Venus is cadent but in its own sign of dignity, and that if Venus were in Aries it would be in its sign of detriment. Anyone not able to confidently follow that level of astrological narrative is advised to gain more astrological experience before undertaking this study of horary astrology.
