The purpose of this study was to improve the evaluation proficiencies of high school distributive education teachers in Virginia. A special conference for selected high school distributive education teachers provided instruction in the preparation of evaluation units and actual construction of such units in selected areas. An evaluation of the conference was based on: (1) pretest and posttest measurements of cognitive abilities in principles of evaluation, (2) the construction of evaluation units, and (3) a followup of the participants' implementation of these skills in the actual school setting. Results of the conference were favorable for all three areas. It was therefore recommended that conferences of this type be viewed as worthwhile ventures for improving evaluation abilities of teachers in their respective fields. (Author/JS)
