The study of task identification in interior design and furnishings presents statistical correlations of task performance frequencies obtained by questionnaire in 16 task clusters for the occupations of assistant interior designer, floor mechanic, upholsterer, and drapery maker. One-way matrices present, for each occupation, task clusters and tasks within each cluster arranged vertically in descending order of overall mean frequency of performance. Two-way matrices correlate task information for all four occupations, with occupations arranged horizontally and task clusters and individual tasks within each cluster arranged vertically in descending order of commonality of performance as indicated by overall mean frequency scores. A two-page bibliography is included together with six appendixes, which provide a list of resource personnel, a task checklist and instruction sheet, personal descriptive data of employees in the four occupations, mean frequency tables for task clusters by individual occupations, alternate job titles by occupations, and mean frequency tables for task clusters for the four occupations.
