Answer: (1) Evaluation aims at promoting the development of preschool education. The fundamental purpose of preschool education evaluation is to improve the level of preschool education and promote the development of every child, which is determined by the nature of preschool education evaluation itself. A good pre-school education evaluation can promote the development of pre-school education, and a bad pre-school education evaluation will hinder the development of pre-school education.

(2) Pay attention to the combination of self-evaluation and other evaluation. Modern pre-school education evaluation advocates the appraisee's participation in the evaluation process, and emphasizes that the appraisee realizes self-improvement through self-analysis and self-knowledge. In the evaluation process, the evaluator and the appraisee should constantly talk and revise each other to make the results as consistent as possible.

(3) Attach importance to the combination of qualitative and quantitative evaluation, and combine objective evaluation with subjective description.
