This report contains information on the background of and research on the North Carolina Kindergarten Entry Assessments (NC KEA). Evidence shows that implementing formative assessment is difficult for teachers and schools. Given that North Carolina will be adopting a new KEA measure for the fall of 2020, this report summarizes previous research on the NC KEA, as well as formative assessments throughout the United States, in order to provide a set of data-based recommendations to help support implementation during this transition. The recommendations provided in this report can be divided into three broad areas: (1) initial and ongoing professional development; (2) supporting implementation practices; and (3) administrative best-practices.
