This study examined the extent to which the role of the assistant principal is perceived to include instructional leadership behaviors. Specifically, this study compared the perceptions of instructional leadership practices of elementary, middle, and high school assistant principals from the perspectives of assistant principals, principals, and teachers. A nonexperimental comparative design was used. Quantitative data were collected via a version of the Principal Instructional Management Rating Scale that was adapted for application to assistant principals. Analysis of variance, independent-samples t-test, correlation, and nonresponse bias analysis were conducted. Effect size and standard error were calculated. Results indicated that the mean scores given by principals were the highest given by any of the three role groups and those given by teachers were the lowest including the lowest seven mean subscale scores among all role groups. Analysis of variance and t-test results of survey responses indicated that, though statistically significant differences were identified regarding school level, gender of the assistant principal, and role of the rater, no practical differences were found. Results further indicated that there was a negligible relationship between experience and ratings of assistant principal instructional leadership. Recommendations include those related to suggestions for continued research on this topic as well as implications for the practice of instructional leadership for assistant principals.

The purpose of this study was to determine the extent secondary assistant principals in large Texas high schools demonstrate behaviors consistent with what the literature describes as instructional leadership. Three hundred seventy principals and assistant principals of large Texas high schools participated in this study. The Principal Instructional Management Rating Scale (Hallinger, 1987) was used to quantify instructional leadership in 10 different job functions. The study found that (a) assistant principals perceive themselves as exhibiting instructional leadership behaviors at a high frequency, (b) principals perceive their assistant principals exhibiting instructional leadership behaviors at a high frequency, (c) the perceptions of the principals and assistant principals were similar, and (d) principals and assistant principals reported more engagement in instructional leadership responsibilities and felt more pressured over the last five years under the new accountability and rating requirements of No Child Left Behind and the state assessments. These findings suggested that the administrative roles and responsibilities in high schools should be restructured to allow assistant principals to focus on instructional leadership.
