In the United States, the practice of iridology is totally unregulated or licensed by any governmental agency or professional organization. Anyone can claim to be an iridologist with training that ranges from a couple of days to a full course in naturopathic medicine.
Practitioners trained by the Institute of Applied Iridology (IAI) in Laguna Beach, California, have an education program modeled after the European style of practice. Theirs is a detailed course (72 hours of classroom study, held over several weekends) culminating in both oral and written examinations with certification, if successful. Naturopaths trained at Bastyr University in Kenmore, Washington, can also avail themselves of an elective course in iridology similar to that given by the IAI.
If you are seeking an iridologist, try to find one who is either certified by the Institute for Applied Iridology or by the International Iridology Research Association (IIRI) in Solana Beach, California. Unfortunately, among the approximately 10,000 individuals calling themselves iridologists in the U.S., no more than 150 or so actually meet the standards of certification.
