Background: The past half-century has resulted in a substantial expansion of early childhood center-based care in the United States. Today, over 74% of American children aged 3-5 attend center-based care (U.S. Department of Education, National Center for Education Statistics, 2021). Although public pre-k is considered socially favorable,…

Background: Inequality along racial and economic dimensions is well-documented and widespread in educational contexts. Achievement gaps are observed among children as early as primary school and are especially notable in standardized testing (Fryer & Levitt, 2004; Fryer & Levitt, 2013; Bond & Lang 2013). In response, some observers and…

Background: Early-grade reading proficiency is well documented as in important factor for later academic success. Researchers and educators consider the achievement of reading proficiency by the end of grade three to be crucial to future academic success and financial independence (Hein et al., 2013; La Paro & Pianta, 2000; Singh, 2013). As…

Background/Context: Pass/fail standardized exams frequently selectively rescore failing exams and retest failing examinees. This practice distorts the test score distribution and can confuse those who do analysis on these distributions. In 2011, the Wall Street Journal showed large discontinuities in the New York City Regent test score…

Background/Context: Spurred by changes in federal policy, Response to Intervention (RTI) has witnessed increased adoption across states and districts in the past several decades (Berkeley et al., 2020). Originating in the special education field, RTI involves a shift from a uniform instructional approach to a tiered instructional approach…

Background/Context: Impact evaluations of schooling reforms in developing countries typically focus on tests of student achievement that are designed and implemented by researchers. Are these tests any good? What practical and principled guidance should researchers in the field follow? We aim to answer these questions. Test scores have, of course,…

Background: Over the last twenty years, retention has increased in popularity with policymakers who are concerned with student achievement and aim to end social promotion (i.e., the practice of advancing a student to the next grade level although they have not yet met the academic expectations of their current grade level). Despite calls to expand…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Despite increases in college enrollment, college completion rates have not kept up, at both 2-year and 4-year institutions. In California specifically, the 6-year graduation or transfer rate for students at 2-year institutions was only 48%. In response to the idea that students arrive at college unprepared, driving these low college success rates,…

Context: Improving teacher quality and granting every student equal access to high-quality instruction have been a shared goal of many parents, educators, and policy makers for decades. In practice, teacher qualification measures (e.g. teacher degree, years of experience etc.) are often used as proxies of teacher quality. However, Shulman (1986)…

Gender achievement gaps on national and state assessments have been a popular research topic over the last few decades. Many prior studies examine these gaps in different subjects (e.g., mathematics, reading, and science) and grades (typically kindergarten through eighth grade) for students living in various regions (typically states or countries)…

Prior research demonstrates the existence of gender achievement gaps and the variation in the magnitude of these gaps across states. This paper characterizes the extent to which the variation of gender achievement gaps on standardized tests across the United States can be explained by differing state accountability test formats. A comprehensive…

Mastering mathematics is important for all students, not only because such success increases college and career options and prospects for future income, but also because mathematics literacy helps citizens and policy leaders to make sound judgments (NMAP, 2008). Research suggests that the rural achievement gap can be addressed with modifiable…

Middle school math placement and progression are topics that are part of an active policy and practice discussion in California and elsewhere. Beginning in the 2008/09 school year, California's State Board of Education recommended that students complete algebra I by the end of grade 8. Between 2003 and 2009 the proportion of grade 8 students…

Preschool reading readiness is an issue with growing interest. The preschool years provide an opportune time when reading difficulties are more easily altered through exposure to early literacy skills. This paper extends the authors' previous research by examining the kindergarten performance of a cohort of children from a multi-year research…
