1. First of all, we should pay attention to objectivity when writing the comprehensive evaluation of parents and children in junior high schools. The evaluation content should truly reflect the performance of students in all aspects, and there should be no subjective assumptions and prejudice.

2. Secondly, the evaluation content should be operable. This means that we need to subdivide the evaluation indicators into specific behaviors and performances, rather than generalizing them. For example, we can evaluate students' academic performance from the aspects of learning attitude, learning habits, learning methods and so on.

3. Third, when evaluating students' physical and mental health, we need to pay attention to the scientific nature of the evaluation content. Evaluation indicators should conform to the scientific concept of health, and there should be no false exaggeration or pursuit of superficial health.

4. Finally, we should pay attention to the timely feedback of the evaluation results. Schools and parents should summarize the evaluation results in time after the evaluation, and give feedback to students in time, so that students can adjust their behavior and performance in time.
