nThis book covers all of the major topics required by the International Iridology Practitioners' Association for basic certification in iridology. It is one of several books available, and while it covers the syllabus requirements for certification, it includes discussions of Rayid and Chakras which are not part of testing requirements. It can be studied as a practice manual but also used as a textbook by any teachers wanting to prepare their students for the certification exam.

The book has full color pages and iris photographs. Visit Betty Sue O'Brian at the Iridology Academy to learn more about textbooks, online courses in Iridology and Sclerology, and for guidance towards IIPA certification. www.iridologyacademy.org
