Gender differences were found in the performance of 103 school administrators (74 men and 29 women) participating in the University of Tulsa's Management Development Program assessment center's evaluations. Exercises included an in-basket, two interviews, an oral presentation, and two leaderless group discussions. Women scored higher on the in-basket exercise and leaderless group discussion. They also scored significantly better in interpersonal competency and the oral presentation. The results were also corroborated by non-cognitive paper and pencil measures of performance. (Author/TE).
