Final answer:
Clarify expectations and base performance evaluations on factors within the control of the school and principal.
Step-by-step explanation:
One solution to enhance performance evaluations in this case would be to clarify expectations. By clearly defining what is expected of students, teachers, and administrators, it becomes easier to assess performance accurately. Additionally, performance evaluations should be based on factors over which the school and principal have control.
For example, instead of solely relying on test scores which can be influenced by external factors, performance evaluations can consider attendance rates, student engagement, and teacher effectiveness. These factors are within the control of the school and principal, and can provide a more comprehensive and fair assessment of performance.
