This study reports the frequency of professional tasks performed by all Wisconsin secondary school industrial education teachers and the importance of those tasks. Data are presented in seven tables and two appendixes. Tables include data on teaching experience, interpretation of median values of frequency ratings, and tasks receiving low frequency and/or importance ratings. Appendix A presents data that show the frequency rating assigned each first-level, second-level, and third-level task, and Appendix B presents data that show the importance rating assigned each task. The ranks are assigned on the basis of the median value. The interquartile range is a measure of agreement among those responding. This study is part of a larger study designed to develop a base for reevaluation of the professional segment of the master of science degree program in industrial education at the University of Wisconsin-Stout.
