The STA’s uniquely structured horary course is designed for astrologers who already understand the basics of chart calculation and interpretation. You don’t need prior training in horary – we provide a complete introduction to its theory, with clear guidance on the most effective principles of judgement and how to apply them in practice.
The course shows how to interpret charts with confidence and clarity, and also how to prepare for the kind of sensitive issues that arise in horary practice. It carries a practitioner-level accreditation, and by the end of the course professional astrologers will be well prepared to include horary in their client services.
Twenty serialised sessions explore horary technique in depth – covering the theory and history of horary, while focussing most strongly on interpretation and engagement with issues that commonly arise in consultation. Our emphasis is on learning through real client scenarios, alongside fascinating historical examples. While rooted in traditional principles, the methodology we teach also draws on modern counselling insights to support the needs of contemporary horary practice. As part of this, we demonstrate a wide range of horary questions — from common client queries to more unusual or challenging examples.
Study groups in this course are carefully structured to ensure that each student receives plenty of personal attention. Every session includes written and interactive tutorials, assignment feedback, and opportunities for one-to-one clarification in addition to group discussion. The course builds steadily, at a digestible pace, designed to offer an accumulated knowledge of horary doctrines in a balanced and accessible way – so that theoretical understanding enhances and inspires (rather than overwhelms) the creative elements of horary interpretation.
This course is carefully designed to make the most of online learning. Each week delivers a themed session through a blend of detailed course notes, media presentations, interactive tutorials, and structured assignments. While sessions are released weekly, students can work through the material at their own pace and on their own schedule – always with direct access to tutor support and the benefit of active study-group discussion.
A typical session includes the following components:
Tutors guide each week’s content and are readily available for questions and clarification at any time. Weekly assignments are generally straightforward – many are instantly graded with automated feedback – but they build in complexity as the course progresses. Later sessions involve judgement exercises that are assessed individually, with personalised critique and tailored tutor commentary. Students are also encouraged to engage in group discussion via the course forums and informal chart discussion sessions – hosted regularly in the latter part of the programme.

Details of the tutors and lecture times/dates are provided in the course Prospectus for each course (see table below for available start dates). The course also provides an active forum for group discussion and several 'student-chart' meetings which provide further opportunity to engage in horary practice and exploration. Our course has gained a great reputation for its excellent level of tutor interaction and student engagement, and no one will miss the opportunity to have their questions addressed in a timely manner by one of our expert tutors.

Texts Grads Forum Testimonials
Although the course material is comprehensive and fully self-contained, many students ask about additional reading. These two titles are highly recommended for horary astrologers and are referenced throughout the course. They’re widely available through international Amazon sites.
The classic text of traditional horary astrology, published in 1647. A full PDF of this work – reset in modern type and annotated with explanatory notes by Deborah Houlding – is available as a free download on the Skyscript website. A hard copy is well worth obtaining at some point – you’ll rarely read anything on horary that doesn’t refer to this work.
A practical guide to the originating theory and working use of house meanings in astrology. Written with the needs of horary practitioners in mind, this book is especially valuable for understanding the symbolic depth of house interpretations and the rulership principles attached to them.
The principles taught in this course provide a firm foundation for exploring other branches of astrology, including natal, medical, electional, and mundane work.

One of the best decisions you can make if you want to learn horary astrology
If you want to learn traditional horary astrology, signing up for the STA Horary Practitioners Level Course is one of the best decisions you can make. Let me tell you why.
Three years ago, I finally decided I wanted to learn traditional astrology. The subject has fascinated me for over twenty years, but each time I opened a book, I felt intimidated by the sheer amount of material to absorb. This time, however, I decided to take the plunge.
In the months and years that followed, I bought more books than I’ll be able to read in a lifetime. The result: I was completely overwhelmed, and more than once I threw those precious books into a corner. What’s even worse: I developed a fear of sitting down and actually reading a chart. I don’t want to be an ‘armchair astrologer’ – but where do I start? When and how do I apply concept X or technique Y? The STA course helped me tackle these problems.
Both the study materials and online classes are very well structured and of high quality. You’ll learn all the key concepts that lie at the basis of horary astrology and traditional astrology in general. Even more important, you’ll learn to apply those concepts as tools to delineate a chart with detail and objectivity.
Parallel to gradually familiarising yourself with the theory behind the art, the course is designed to make you learn by practising. The exercises start at a comfortable level, and with each session you’ll find yourself climbing higher up the carefully designed scaffolding. This is done through a well-thought-out structure of (1) example charts with delineations by the tutors – learning by example – and (2) delineating charts yourself, adding newly learned concepts and techniques as you go – learning by trial and error. Constructive feedback by tutors helps you retrace steps and correct mistakes you might have made.
The flame of my initial enthusiasm has been rekindled, and I’ve gained enough confidence to put everything I learned into practice. The course has ended, but my journey has only just begun. I’m looking forward to revisiting the course materials and doing chart work for people who are in need of advice. I’ll probably stumble in the beginning, but with all that I’ve learned at the STA, I’m confident I’ll stand up again and reach the goal I’ve set for myself.
Do you want to learn traditional astrology? I’ve pointed you the way. May you fare well with the stars as your guide!
