The National Center for Research in Vocational Education (NCRVE) partially supported 10 new or extensively revised leadership development projects at 7 institutions of higher education designed to improve the leadership attributes of graduate students in vocational education. The projects adopted as instructional objectives one or more of the leadership attributes proposed by NCRVE and cooperated in implementing a common evaluation plan. From 180 participants and project directors, NCRVE collected quantitative data about participants' preprogram leadership attributes, satisfaction with the program, postprogram attributes, and leadership behavior and performance 6 months after the program as well as qualitative data about perceptions about effectiveness of program activities. Meta-analysis results indicated the following: participants were very satisfied with the programs and believed they were of great value to their professional development; overall, the programs had a significant impact on the participants' perceptions of their leader attributes; the number of leader attributes that improved significantly appeared related to certain program characteristics; programs were not very successful in developing prespecified attributes; and of the six attributes that best explained leader effectiveness, two (adaptable, open to change and insightful) readily improved and two (team building and willing to accept responsibility) were more resistant to change.
