The paper describes the task matrix procedure for determining the task content for work samples in entry-level occupations within a specified occupational group or industry. The procedure enables the work sample developer to systematically obtain and organize task information from the Dictionary of Occupational Titles in order to identify those tasks to be included in the work sample. The four basic steps in using the task matrix procedures are described in detail: (1) determining the basis for work sample development, (2) locating entry-level occupations, (3) developing the task matrix, and (4) identifying the work sample tasks. Appended materials include a five-item bibliography and a list of entry-level worker trait groups as indicated in the Dictionary of Occupational Titles, Volume 2. (Author/BP)
