Welcome to the ISAA
The International Sidereal Astrology Association (the ISAA) is a nonprofit organization dedicated to preserving, promoting, and advancing Sidereal Astrology as a rigorous, research-based discipline rooted in the observable sky. We support a diverse community of professional astrologers, students, and researchers who align their work with the actual constellations and fixed stars, rather than relying on tropical placements. Through education, certification, collaboration, and outreach, our goal is to foster excellence within the field and to connect a global network of sidereal astrologers who uphold the highest standards of accuracy, integrity, and astronomical relevance in their astrological practice.
