This curriculum guide for environmental health is intended as a reference tool to aid institutions in establishing or revising their curriculum. After a brief introduction discussing competency-based curriculum for environmental health, the guide presents information on the following tasks or elements necessary in developing a competency-based curriculum: (1) defining the performances; (2) defining knowledge, skill, and attribute competencies; (3) defining objectives; (4) learning opportunities; (5) curriculum sequence; (6) teacher strategies; and (7) student appraisals. A definition of the profession of environmental health is included, and recommendations to be followed in developing a program are given. A discussion of problems and solutions and a list of references concludes the guide. Several supporting materials are appended, such as the Role Delineation Instrument and the Blueprint of the Knowledge, Skills, and Attributes for Environmental Health Practitioners. (BM)
