Principal preparation programs are designed to ensure that candidates who successfully complete the programs are qualified and knowledgeable, and have had leadership experiences that prepare them to compete for leadership positions in today's schools (Hale S.z Moorma, 2003). Providing meaningful leader-ship experiences in non-internship programs can be a challenge. The purpose of this study was to evaluate the impact of candidates' field experiences in leadership based on a locally developed pre and post self assessment. The instrument consisted of 54 items developed around the California Professional Standards for Educational Leaders (CPSEL). Results indicated significant differences in candidates' perceptions of their pre and post levels of experience as evidenced by mean score and matched case comparisons. The impact of entry level years of experience was examined. Implications and future program enhancements based on the results are included. (Contains 2 footnotes and 4 tables.)
