This study compares School Leaders Licensure Assessment (SLLA) sub-scores with principal interns' self-assessment sub-scores (ISA) for a principal internship evaluation instrument in one educational leadership graduate program. The results of the study will be used to help establish the effectiveness of the current principal internship program, performance on the School Leaders Licensure Assessment, and provide suggestions for program improvement. The researcher compared the sub-scores for the multiple choice section of the SLLA with sub-scores from the university's principal interns' self-assessments to look for correlations between the two data sets. The results indicated a positive correlation in two areas of the study.
