The process of teacher evaluation has often been less than satisfying for both teachers and administrators. Educational literature dealing with teacher evaluation shows that it is frequently a rote procedure with little or no benefit for the people involved. In this study, the researcher used the action research process to design, implement, and evaluate a new system of teacher evaluation and development in St. Anne's Catholic School. Twenty teachers of the twenty-two member faculty participated in the two-year study. Together, the teachers and administrator examined the original system of evaluation and then devised a new system. They put the new process into effect, critiqued it, and revised it. The administration and faculty learned that teacher evaluation can be more meaningful if teachers are involved in its planning, given a choice of evaluation methods, and evaluated consistently throughout the school year.
