In 2014–15, boys had higher fourth-grade math scores than girls, but no significant differences were found in boys’ versus girls’ fourth-grade reading knowledge and skills. These findings come from the most recent data release for the Early Childhood Longitudinal Study, Kindergarten Class of 2010–11 (ECLS-K:2011). A recently released report provides a first look at the status of students who were in kindergarten for the first time during the 2010-11 school year and were in fourth grade in 2014-15. The longitudinal nature of this study allows for a comparison of trends over time. For example, differences in math scores between boys and girls were also observed in third grade but not in earlier grades. No significant differences in reading results for boys and girls have been detected in any grade between kindergarten and fourth. More data on assessment scores, as well as the demographic and family characteristics of the cohort of students who were first-time kindergartners in 2010-11, are available in the reports.
The series of Early Childhood Longitudinal Studies are consistently some of the most popular NCES studies due in large part to the fact that they provide comprehensive and reliable data on important topics such as child development, school readiness, and early school experiences. The ECLS-K:2011 was designed to provide data that can be used to describe and to better understand children’s development and experiences in the elementary grades, and how children’s early experiences relate to their later development, learning, and experiences in school. The study is longitudinal, meaning that it followed the same group of children over time; in the case of the ECLS-K:2011, children were followed from their kindergarten year (the 2010-11 school year) until the spring of 2016, when most of the children were in the fifth grade.
All planned waves of data through fifth grade have been collected and staff at the National Center for Education Statistics (NCES) are hard at work releasing reports of the findings as well as the data from all rounds of the study. Researchers, educators, policy makers, and other interested members of the public now have access to much of the important data from the ECLS-K:2011, with additional reports and data releases on their way.
The diverse sample of children who participated in the ECLS-K:2011 is nationally representative of students who were in kindergarten in U.S. schools in the 2010-11 school year. Information on children’s cognitive, social, emotional, and physical development was collected every year using direct child assessments and surveys for the adults central to the children’s education. Adults surveyed for the study included the children’s parents/guardians, their teachers, their school administrators, and their kindergarten before- and after-school care providers. Topics covered by the surveys included the children’s home environment, home educational activities, school environment, classroom environment, classroom curriculum, teacher qualifications, and before- and after-school care.
Public-use data from the kindergarten through fourth-grade rounds of the ECLS-K:2011 are now available online. A restricted-use dataset with data from the kindergarten through fourth-grade rounds is also available to qualified researchers with an IES Restricted-use Data License.
