During the summer of 1965, an experimental group of 12 school administrators participated in sensitivity training sessions to measure the influence of the sessions on situations involving administrative change. The study tested: (1) Behavior of administrators in meetings in their school system; (2) behavior toward subordinates; (3) skill in diagnosing problems; (4) ability to see alternative strategies in diagnosing problems; and (5) influence on nonparticipants in their school systems. Measurement instruments compared this experimental group with a control group in discussion of issues in school, sensitivity to problems in staff and administrative meetings, interaction with subordinates, and organizing of subordinates. The study concluded that a one-shot laboratory training experience, conducted outside the context of the participants' organizational system, is not a very effective tool for initiating and maintaining significant behavior change in the back-home situation.
