Purpose, Scope, and Method of Study. The purpose of this study was to determine the nature of Oklahoma public school superintendent evaluations. Based on the perceptions of public school superintendents serving in independent school districts in Oklahoma, this study sought to describe the procedures by which superintendents are evaluated. The study further sought to determine the frequency, purpose, criteria, and instrumentation of evaluations. Finally, the study sought to determine if district size, based on student enrollment, significantly affected the nature of the superintendent evaluations. This was a quantitative nonexperimental study using a descriptive survey research model. A questionnaire was developed and administered to all superintendents of the 420 school districts in Oklahoma that offer kindergarten through twelfth grades. A 50% return rate was achieved with 209 useable surveys returned. The questionnaires were grouped for analysis based on the school district size indicated on the survey. The descriptive statistics from the survey data were examined for significance using a chi-square analysis to determine if district size impacted the nature of the survey responses. Findings and Conclusions. Oklahoma superintendents were similar to superintendents across the nation in regard to their demographics. Most Oklahoma superintendents tended to be Caucasian males above the age of 50 with more than 5 years experience as a superintendent. The nature of Oklahoma superintendent evaluations was also comparable to national trends. Oklahoma superintendents tended to be formally and annually evaluated by all members of their school boards. Employment and accountability were commonly the primary purposes of Oklahoma superintendent evaluations. The school board and superintendent relationship was often the most important criterion, and a checklist or rating evaluation instrument was most often used. Most Oklahoma superintendents were satisfied with the process used to evaluate their performance. [The dissertation citations contained here are published with the permission of ProQuest LLC.
