There exist passionate debates about the best way to teach children to read. Since the Bush administration, school districts receiving federal funds have been required to have research evidence justifying their methods of teaching reading, and in recent years the need for evidence-based practices have intensified with the "Science of…

Of critical importance to education policy is monitoring trends in education outcomes over time. In the United States, the National Assessment of Educational Progress (NAEP) has provided long-term trend data since 1970; at the state/jurisdiction level, NAEP has provided long-term trend data since 1996. In addition to the national NAEP, all 50…

Educational inequality due to family socioeconomic status (SES) has been the focus of both public dialogue and education research in the United States for many years. The current study aims to understand how educational inequality due to family SES has changed in the United States. Specifically, the study focuses on the changes in achievement gaps…

Social scientists have found income inequality is associated with an array of health and social problems, however the implications of income inequality for educational outcomes have not been investigated as thoroughly as other domains. In this study, I investigated how income inequality was associated with 4th grade academic achievement using…

COVID-19 gave the country a crash course in public health data. It underscored the value of data that can support well-informed, timely action in a crisis. Good data are just as important for education systems in crisis. Schools and districts have been struggling to reach and educate students safely. Students who were disproportionately…

We use data from the Stanford Education Data Archive to describe district-level trends in average academic achievement between 2009 and 2019. Although on average school districts' test scores improved very modestly (by about 0.001 standard deviations per year), there is significant variation among districts. Moreover, we find that average test…

Rising inequality in the United States has raised concerns about potentially widening gaps in educational achievement by socioeconomic status (SES). Using assessments from LTT-NAEP, Main-NAEP, TIMSS, and PISA that are psychometrically linked over time, we trace trends in SES gaps in achievement for U.S. student cohorts born between 1961 and 2001.…

This paper describes progress, challenges and opportunities of using policy to advance educational equity and excellence at scale in the United States. It begins with a look-back that examines two key elements of the standards-based education (SBE) era: First, it traces policy shifts and implementation challenges of the SBE era. Second, it…

Scores from the National Assessment of Educational Progress (NAEP), dubbed the "nation's report card," are often used to compare student achievement across states. An important limitation of NAEP is that it does not track the performance of individual students over time, so inferences about how much students are learning must be made by…

The National Assessment of Educational Progress (NAEP) -- often called "The Nation's Report Card" -- is the largest nationally representative and continuing assessment of what students in public and private schools in the United States know and can do in various subjects and has provided policy makers and the public with invaluable…

This paper examines national gaps and trends in geography achievement in eighth grade from 1994 to 2018. Statistical models comprising student- and school-level variables were developed to predict achievement using data provided by the National Assessment of Educational Progress (NAEP). Although there were statistically significant relationships…

Two major reforms have transformed California's K-12 education system over the past decade. To revamp English and mathematics instruction, the Common Core standards were adopted in 2010, with district implementation beginning several years later. In 2013, the Local Control Funding Formula (LCFF) was enacted to increase funding for disadvantaged…

Using National Assessment of Educational Progress data from 2003 to 2015, this brief describes changes in the reading and mathematics performance of multilingual students--defined as students who report a primary home language or languages other than English. Although all students' scores improved, multilingual students' scores improved two to…

The Trends in International Mathematics and Science Study (TIMSS) makes it possible to compare the performance of students in the US in Mathematics and Science to the performance of students in other countries. TIMSS uses four international benchmarks for describing student achievement: Low, Intermediate, High, and Advanced. In this study, we…

Rising inequality in the United States has raised concerns about potentially widening gaps in educational achievement by socio-economic status (SES). Using assessments from LTT-NAEP, Main-NAEP, TIMSS, and PISA that are psychometrically linked over time, we trace trends in achievement for U.S. student cohorts born between 1954 and 2001. Achievement…
