Effective feedback and evaluation are contingent on a number of components . They:
- are based on observation of the student’s performance.
- adhere to the guidelines and intent of the educational program.
- provide a fair and balanced picture of the student’s skill level and achievement (they avoid Halo Effect, Mum Effect, Leniency Bias/Error, and Contrast Error).
- summarize the feedback that has been delivered up to the time of evaluation (no surprises).
- are an interactive process, taking place during an ample amount of scheduled time, in a quiet and private environment.
