The Early Childhood Longitudinal Study Project of Kindergarten Class (ECLS-K) in the U.S and Its Enlightenment

美国早期儿童纵向研究幼儿园项目（ECLS-K)，是由美国教育部国家教育统计中心（NCES)于 1998年联合多个部门和单位，纵向跟踪了来自全美不同阶层家庭的22000名儿童，旨在通过研究为政策制定者 和社会科学家提供具有全国代表性的参考数据信息。该研究项目既收集了儿童个体发展发育的信息又收集了大 量相关的统计数据，如种族，性别，家庭结构，社会经济地位，父母教育程度，子女数量等。该研究项目所呈 现出的系统性、科学性、全面性和长效性值得我国适时开展相关儿童研究借鉴。

The Early Childhood Longitudinal Study Project of Kindergarten Class (ECLS-K) in the U.S， in which 22000 children from different class families across the United States have been tracked from kindergarten to the eighth grade，was started in 1998 by the National Center for Education Statistics (NCES) under the U.S. Education Department， together with many departments and institutes. The research aimed to provide nationally representative reference data information for policy makers and social scientists. In addition to collecting information of children’s individual development， the project also collected a large amount of related statistical data， such as race， gender， family structure，social and economic status， parents’ education levels， number of children， etc. The systematic， scientific， comprehensive and long-term feature of the research project can be helpful to carry out the relevant children study in China.
