Childcare assessment is an important measure to standardize the behavior of childcare institutions,improve the quality of childcare services,and promote the physical and mental health development of infants and young chil-dren.It is also an important component of childcare institution management.Building a professional competence in-dex system for childcare evaluators is a key element in standardizing the conduct of childcare evaluations.Through the Delphi method,three rounds of expert consultation were conducted to construct a professional competence index system for childcare assessors,which includes 3 primary indicators—professional philosophy and ethics,evaluation foundation and skills,and evaluation organization and implementation,7 secondary indicators,and 23 tertiary indi-cators.This system provides a theoretical basis for the professional development and improvement of childcare as-sessors,and promotes the high-quality development of the childcare industry.
