This study examines the perceptions of superintendents regarding the use of multi-source assessment (MSA) as part of superintendent evaluation. Known users of MSA were asked to participate. MSA users are difficult to find and those using it successfully do not understand why more were not interested in using the process. Each superintendent received a survey asking for their perceptions on the advantages, pitfalls, criticisms, rationales for use, and other items about MSA. Several participants were interviewed to gain insight into their MSA experiences concerning how they learned about MSA; bringing MSA to use; MSA implementation; effective experiences; ineffective experiences; and comparing MSA to other evaluation methods experienced. Self-directed users like the feedback driven nature of MSA. These individuals utilized their leadership teams to bring the process to reality and found the process to beneficial and better than other evaluation methods; providing them with information beyond the typical superintendent evaluation. Users who did not initiate MSA usage were not as favorable to the process as the self-directed users. They perceived it as a way to support job action against them. Such a concept goes against the guidance provided by Edwards and Ewen (1996). Recommendations include educating superintendents on the topic by self-directed long-term users at superintendent conferences; educating school board members on how MSA can be used; considering MSA as a component of a revised superintendent evaluation model being developed in Missouri; and establishing user groups to share best practice.
