This quantitative study, utilizing the backward method of multiple regression, examined the relationship between the length of tenure of a superintendent and academic achievement as defined by the percentage of students who scored "Proficient" or better on the 2008 Third Grade Kansas Reading Assessment. To put this relationship into context, five other predictive variables were included as a part of this study: the individual's total length of experience as a superintendent, the superintendent's total length of experience in education, each district's assessed valuation per pupil, each district's percentage of students who qualified for free or reduced meal prices, and each district's total student headcount. To gain the most comprehensive view possible, all 295 Kansas school districts in existence in 2008 were included in this study. Although included as one of the four predictive variables that had a significant effect on the percentage of students who scored "Proficient" or better on the 2008 Third Grade Kansas Reading Assessment, the primary focus of this study--to examine the impact a superintendent's length of tenure has on students' academic achievement--proved to have the least relative impact, according to beta weights.
