Next to many of the courses in the System Course Chart and in the Course Description section, you will notice a code letter in parentheses. The code letter indicates that the course is required as part of an UTC instructor and practitioner training. One or more courses may be required for instructor and practitioner certification for the level represented by the letter. A prospective instructor and practitioner must be experienced and competent in the practices taught in the course. An instructor and practitioner candidate must also demonstrate the ability to teach the related contents of the course to the public.

For example: Cosmic Inner Smile, Wisdom Chi Kung, Cosmic Six Healing Sounds, Awaken Cosmic Healing Energy (Microcosmic Orbit), World Link Meditation and Chi Self-Massage each have the "(M)" code letter beside it. This means that these courses are part of the Microcosmic Orbit instructor certification. New instructor candidates must be proficient in each of these courses. Previously certified instructor must update their training to include the more recent modifications in the courses offered.

The following list shows the codes for UTC instructor and practitioner categories.
