A mail survey of vocational-techncial teachers in Texas was conducted to identify tasks performed, knowledge required, and amount of time spent in the performance of these tasks. A questionnaire was given to 1,149 vocational-technical teachers with 85 percent responding. The teachers were classified according to vocational program areas and were asked to identify the tasks they performed and the time spent on each of 105 given tasks in the areas of: instructional planning, execution, and evaluation; program planning, development, and evaluation; management; guidance; school-community relations; student vocational organization; professional role and development; and coordination. Data are arranged according to vocational education program areas and a composite analysis of the data across program areas was also performed. Each task was analyzed in the following areas: rank by percent of respondents performing, cumulative sum of average percent time spent by all respondents, average percent time spent by all respondents, average percent time spent by respondents performing, and percent of respondents performing. It was concluded that the respondents could identify the tasks performed and the amount of time required. The research offers useful information for curriculum decision making and developing instructional programs. A bibliography is included and the questionnaire appended. (EC)
