This competency-based horticulture curriculum guide is designed to provide secondary and postsecondary horticulture teachers with a task-oriented program for training turfgrass maintenance workers. It contains a master resource list, a listing of turfgrass maintenance resources available from various states, and 59 competency task sheets organized into 11 competency areas. These areas are equipment operation and maintenance; general turfgrass maintenance; maintenance of trees and shrubs; maintenance of greens and trees; maintenance of fairways, roughs, and traps; maintenance of water hazards; maintenance of facilities; ground preparation; propagation and growth; harvesting; and maintenance. A task statement, a performance objective, suggested learning activities, evaluation procedures, selected resources, and a performance guide are provided in each competency task sheet. Instructor checklists designed to help instructors determine acceptable levels of student performance are also included in the units. (Related competency-based horticulture curriculum guides in the areas of gardening/groundskeeping and floriculture are available separately through ERIC--see note.) (MN)
