The superintendent's role has shifted from one that was primarily focused on management, to one that now includes more accountability, student achievement, and instructional leadership functions along with management. For many districts, evaluation procedures of the chief executive have not kept pace with this movement; consequently, an updated state recommended evaluation tool is long overdue. The Missouri Department of Elementary and Secondary Education (MDESE) established an ad hoc committee, which will be referred to as the state committee for the remainder of this project, to review and revise the 1986 version of the Performance Based Superintendent Evaluation (PBSE), and proposed an updated instrument aligned with national standards. Upon adoption, it would replace the 1986 model, currently endorsed by MDESE. Under Missouri statute, MDESE is required to provide suggested guidelines for an evaluation instrument. After conducting surveys and interviews with school board members and superintendents who piloted a draft of the proposed PBSE, the learning team analyzed and developed recommendations for review and revision by the state committee. Further, the learning team developed a model implementation plan of the proposed PBSE instrument for potential use by Missouri school boards. The final goal is the adoption and implementation of a new PBSE by MDESE to replace the 1986 model. The proposed PBSE will address accountability standards, the increased focus on student achievement, and the changing role of the superintendent as the instructional leader of a school district.
