It is not intended to be a stand-alone publication. Included in this document are sources of information for determining such things as (1) whether there is a considerable amount of theory to be taught with the task under consideration; (2) whether the task must be performed immediately on entry to the job; (3) whether the task is a prerequisite for learning and/or performing other school trained tasks; and (4) whether the task can be learned with very little supervision. Information is also included on how to conduct field surveys and how to organize panels of experts. (LLS)
