In this article, the PACT Coordinator and former Department Chair of the Department of Secondary Education at a large state university describe how the PACT Teaching Event was introduced, piloted and implemented in their department. Despite the size and complexity of this department, PACT implementation went relatively smoothly, with widespread and positive participation by full-time and part-time faculty. The authors explain the successful implementation, drawing on data from faculty focus groups and campus leaders. The authors give recommendations for large-scale credential programs that are considering implementing a high-stakes teacher-performance assessment.
