This is an occupational survey report of the Diet Therapy career ladder, AFSC 4D0X1. This survey was initiated by the Air Force Occupational Measurement Squadron (AFOMS) to obtain a comprehensive list of tasks performed and equipment used, as well as the specific types of diets for which menus are prepared in this career program. In addition, OSR data were needed to support a utilization and training workshop (U & TW) conducted May 1994 at Sheppard AFB TX. The last survey pertaining to this specialty was published in December 1985. As described in AFMAN 36-2108 Specialty Descriptions, dated April 1991, personnel in this career ladder prepare, cook, and serve routine and therapeutic diets and nourishments for personnel under medical treatment; perform clinical dietetics tasks; and accomplish subsistence and supply management in medical food service facilities. In addition, 7- and 9-skill personnel supervise and superintend medical food service activities. To qualify for AFSC 4D0X1, personnel must first complete a preparatory training course (L3AQR4D03 1 001) which covers preparing, cooking, and serving food. This is a 6-week, 4-day course conducted at Lackland AFB TX and is the same course given to Morale, Welfare, Recreation (MWR) and Service Specialists in AFSC 3M0X1. After this course, personnel must complete a basic technical training course (J3ABR4D03 1 001) administered by the 82d Medical Training Group at Sheppard AFB TX.
