KNOS stands for Kinesiology National Occupational Standards. These are to ensure that all kinesiologists are qualified to a high standard.
Those who belong to a professional body such as the Kinesiology Federation (KF) or the Federation of Holistic Therapists (FHT) have proven they meet these standards.
In order to meet the standards a kinesiologist will have undertaken a Foundation Training, Practitioners Course, Interpersonal Skills, Practice Management, Human Anatomy and Physiology and Nutrition Studies. These are all part of the KNOS.
