This list consists of essential competencies from the following specialized Ohio Competency Analysis Profiles: Floriculutre and Greenhouse Worker; Nursery and Garden Center Worker; and Turf and Landscape Worker. Developed through a modified DACUM (Developing a Curriculum) process involving business, industry, labor, and community agency representatives in Ohio, this document is a comprehensive and verified employer competency profile for horticulture occupations. The list contains units (with and without subunits), competencies, and competency builders that identify the skills needed to enter these occupations. The occupational, academic, and employability skills for this occupational area are included. Within the outline are three levels of items: core, advancing, and futuring. Core items identify the knowledge, skills, and attitudes essential for entry-level employment.
