This brief report provides a first look at the overall third-grade reading, math, and science achievement of the students who were attending kindergarten for the first time in the 2010-11 school year and were in third grade in the spring of 2014 using new data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010–11 (ECLS-K:2011). It is intended to provide a snapshot of the third-grade achievement of the children who were first-time kindergartners attending school in the United States in 2010-11 and to show readers the kinds of data that are available, in order to encourage more in-depth analysis using more sophisticated statistical methods. Reading, mathematics, and science assessment scores in the spring of third grade are shown, both overall and by selected child, family, and school characteristics.
