The manual was designed to help vocational education curriculum experts learn procedures for constructing task inventories and for analyzing occupational performance. The manual opens with definitions of a task inventory and other terms, and an overview of the procedure. The first six steps involve the overall construction of an initial task inventory (define scope of performance situation; locate written sources of activity statements; draft task and duty statements; obtain knowledgeable consultants to review, edit and group items; and pilot test items). The second six steps cover the acquisition of information about each task (determine task information needed; determine appropriate job incumbent sources; prepare and pilot test questions; develop sampling plan and analysis design; print questionnaire; and administer questionnaires). The final five steps describe the analysis of the task data derived from the previous steps (develop inventory record procedures; key punch task inventory data; compute general summary statistics; record additional tasks written in by respondents; and prepare report of analysis results). Each of these three sections concludes with selftest items, designed to help the readers evaluate their learning of the concepts introduced. Duty statements, background information questions, the inventory and instructions, and sample letters are appended. (JB)
