Ten elementary and secondary school principals worked with the project director and consultants to select and develop instruments, procedures, and experiences that would help principals become more effective in their leadership roles. On the basis of the experiences gained from the five general workshops and the field trials, the project principals developed a package of instruments and procedures they believed to be of significant value to all school principals and administrators. This document describes the development of the package and evaluates the success of the project. Topics considered in the package include leading effective meetings, communicating with others, organizational style, establishing objectives, time stewardship, and problem solving using force field analysis. The learning package for principals is included in the appendix. (Author/DN)
