The use of the team process in school improvement plans may play a role in how effective the group is in achieving its goals and objectives. Representative efforts and perceptions of the use of teams in local educational agencies were surveyed in multiple measurements, such as interviews, self-assessments, self-perceptions, and observations. The results indicated that core teams were not analyzing their team process, and, therefore, the individual members had very different perceptions about where the team was developmentally which, in turn, impacted their self-perceived effectiveness. The findings and summary indicated that the team concept was central to all the school districts involved in school improvement plans. Nine out of 10 districts surveyed felt the need for assistance in team process skills. Most teams said they utilized consensus as a decision making method but indicated difficulty in the area of dealing with conflict. A Delta Team self-analysis and accompanying records provide a team process example and a case history. Recommendations for accepting, adopting, and enhancing team building are included in an inservice process workbook of activities to be used in developing group facilitation. (Author)
