About one in five students in the US attends a rural school, and over half of all school districts are in rural areas. And yet very little is known about achievement, achievement gaps, and academic growth in rural schools, including how school-year and summer changes in achievement may differ in these schools. This lack of information is…

Using a national sample of kindergarten to eighth grade students from Catholic and public schools who took MAP Growth assessments, we examine achievement growth over time between sectors. Our findings suggest that while Catholic school students score higher in math and reading than public school students on average, they also enter each school…

States have invested heavily in improving early childhood education in hopes of improving student reading and math skills before they enter kindergarten. However, there is limited national data from later than 2010 on children's skills in these areas at kindergarten entry, so it is difficult for educators and policy makers to ascertain whether…

Important educational policy decisions, like whether to shorten or extend the school year, often require accurate estimates of how much students learn during the year. Yet, related research relies on a mostly untested assumption: that growth in achievement is linear throughout the entire school year. We examine this assumption using a dataset…

Students' level of academic skills at school entry are a strong predictor of later academic success, and focusing on improving these skills during the preschool years has been a priority during the past 10 years. Evidence from two prior nationally representative studies indicated that incoming kindergarteners' math and literacy skills were higher…

Growing evidence suggests that contrary to popular belief, schools mostly do not generate achievement gaps in cognitive skills but, rather, reflect the inequalities that already exist. In the case of socioeconomic status, exposure to school often reduces gaps. Surprisingly little is known, however, about whether this pattern extends to gender gaps…
