Research on school leadership speaks to the importance of evaluating school administrators. Evidence suggests that involving school leaders in the design of the evaluation process as well as including feedback from stakeholders in the school community as part of the evaluation process can positively impact administrators' professional practice. Effective assessment supports the continued development and growth of school leaders. In the local archdiocese the pastor evaluates the parish school administrator, using a standard form based on the job description and issued by the superintendent's office. The same self-evaluation is completed by the principal and discussed with the pastor. Since the pastor is typically not an educator, questions arise about the accuracy and usefulness of the data generated by the evaluation. These questions lead to discussions about the efficacy of the process and generate ideas for improvement and a willingness to effect change. This dissertation study seeks to identify perceptions of Catholic elementary school principals about the current evaluation process in their diocese, exposes administrators to research into best practice in leadership evaluation, and shows how these principals collaboratively designed an evaluation tool and process. This action research process tracked changes in attitudes and beliefs about effective evaluation that occurred as the administrators designed a new tool and method for potential implementation in their diocese. Trends were identified and coded utilizing the research questions and the theoretical framework of Organization Governance, Leadership Theory, Evaluation Theory and Change Theory. This qualitative research study adds administrator voices to the developing professional dialogue about effective leadership evaluation.
