The field of Environmental Health Technology (EHT) encompasses both the equipment and the trained expertise required to utilize land, water, energy, and minerals in the service of human health and welfare. EHT technicians work in disease control, licensing bureaus, hospitals, nursing homes, hazardous waste agencies, and other health agencies. In Arizona, EHT personnel must be licensed and registered. In response to the state's need for trained personnel in the field, a study was conducted to identify the general competencies and knowledge, and the broad and specific skills that should be included in an associate degree EHT curriculum. EHT personnel at various state and county departments were asked to assess the importance of 18 curricular subjects to their work. An analysis of 10 randomly selected questionnaires from each of five responding agencies suggested that the EHT curriculum should cover, in order of importance: (1) public health laws; (2) sampling techniques; (3) survey and test kits; (4) health problems and priorities; (5) microbiology; (6) epidemiology; (7) program planning and implementation; (8) biology; (9) legal factors; (10) supervisory techniques; (11) systems approaches; (12) group dynamics; (13) public information planning; (14) testing and training aids; (15) inorganic and organic chemistry; (16) survey methods; (17) mathematics and introductory statistics; and (18) audio-visual aids. The survey instrument is appended. (EJV)
