This study sought to determine the effectiveness on increasing student achievement of principals trained in a traditional principal preparation program and those trained in an alternate route principal preparation program within the same Mississippi university. Sixty-six Mississippi principals and assistant principals participated in the study. Of the 66 participants, 41 competed a traditional principal preparation program, and 25 completed an alternate route principal preparation program at the same university. The data included the type of principal preparation the participant received, the number of consecutive years served as a principal or assistant principal, and student achievement data for their assigned schools. The results of this study suggested the type of principal preparation program had no significant impact on student achievement in Mississippi public schools.
