Annual program evaluation

The program conducts an annual program evaluation with the assistance of Program Evaluation Committee (PEC) members which includes the program director, faculty, and residents as part of the program’s continuous improvement process. The PEC members review the current operating environment to identify strengths, challenges, opportunities, and threats as related to the program’s mission and aims. The program evaluates the performance of faculty members based on resident’s feedback.

The program director with input from the Clinical Competency Committee meets with each resident to document a semi-annual performance assessment with each resident to assist the resident in developing individualized learning plans to capitalize on their strengths and identify areas for growth, well-being, and career plans. At the end of each academic year, a summative evaluation is conducted to review the readiness to progress to the next year of the program, if applicable.

An objective performance evaluation based on the Competencies and Milestones is documented at the completion of each assignment. Feedback from faculty members is frequent and not always formally documented. The feedback allows for the development of the learner as they strive to achieve the Milestones.
