Drawing on nationally representative data from six cohorts of beginning teachers from the Schools and Staffing Survey and the National Teacher and Principal Survey, this study applies a difference-in-differences research design to examine the relationship between changes to state-level alternative certification policies and the characteristics of new teachers. The introduction of alternate routes into teaching is associated with an increase in the fraction of new teachers of color in a state and the new teachers who graduated from selective colleges. No evidence was found of a relationship with the relative share of male teachers or teachers of in-demand subjects.

改变初任教师的构成：国家替代认证政策的作用

根据《学校和人员配备调查》和《全国教师和校长调查》的六组新任教师的全国代表性数据，本研究采用了差异研究设计，以检查州级替代认证政策和新教师的特点。将替代路线引入教学中，与州内新任彩色教师和从精选大学毕业的新教师所占比例的增加有关。没有证据表明与男教师或需求旺盛科目的教师的相对比例有关系。
