The science of reading has captured the attention of educators, policy makers, and the public. Elfrieda H. Hiebert recounts some of what she's learned from her recent exploration of the topic. She has found that research evidence tends to fall into three categories: research that provides unequivocal conclusions, research that holds promise for…

The State NAEP program only reports the mean achievement estimate of a subgroup within a given state if it samples at least 62 students who identify with the subgroup. Since some subgroups of students constitute small proportions of certain states' general student populations, these low-incidence groups of students are seldom sufficiently sampled…

Background/Context: Many students in the United States need access to effective writing instruction, with some requiring intensive intervention. Results from the National Assessment of Education Progress (NAEP) in writing over the past 25 years revealed that most students in the U.S. have yet to attain a proficient level of written expression…

This primer summarizes the Education Sciences Reform Act (ESRA), the Educational Technical Assistance Act (ETAA), and the National Assessment of Educational Progress Authorization Act (NAEPAA). The report is organized in a manner that aligns with P.L. 107-279, the law that enacted the three acts. The ESRA authorizes much of the federal…

We are pleased to contribute to this inaugural issue of The Reading League Journal. The journal's goal is to share information about linking reading science to educational practice. The need is great: literacy levels in the US are shockingly low; a very large percentage of children and adults have only basic reading skills, as indicated by every…

Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

Purpose: Writing is an essential skill that secondary students need to establish for success in their further education, careers, and lives. However, most secondary students in the United States do not achieve the level of writing proficiency expected to ensure academic and future success. One approach that is emerging more in the research…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

Regression discontinuity (RD) designs are commonly used for program evaluation with continuous treatment assignment variables. But in practice, treatment assignment is frequently based on ordinal variables. In this study, we propose an RD design with an ordinal running variable to assess the effects of extended time accommodations (ETA) for…

It is a much-lamented fact that research with the potential to inform or influence education policy instead remains policy inert. There are many reasons for this frustrating state of affairs, including a lack of strategic thinking on the part of researchers on how to successfully accomplish outreach--as opposed to communication with peers…

Money matters in education, especially for students from families that are struggling financially. Increasing school funding not only leads to improved school completion rates and higher achievement in low-income school districts, but over the long-term it can increase educational attainment, wages, and family incomes for children from low-income…

When an assessment undergoes changes to the administration or instrument, bridge studies are typically used to try to ensure comparability of scores before and after the change. Among the most common and powerful is the common population linking design, with the use of a linear transformation to link scores to the metric of the original…

The racial achievement gap is one of the most persistent and pervasive issues in educational research. Unfortunately, the current research on Black student achievement lacks empirical studies that address the academic strengths and challenges facing Black girls. Specifically, there is a dearth of resources in the form of books, articles, and…

On September 22, 2017, the National Center for Special Education Research (NCSER) and the National Center for Education Research (NCER) at the Institute of Education Sciences (IES) convened a group of experts in policy, practice, and research related to Career and Technical Education (CTE). The goal of the meeting was to seek input from…

School District Effectiveness Research (SDER) works to identify unusually effective organizations for in-depth qualitative study that significantly outperform peer districts over multiple years. Yet, critiques of SDER include a focus on cross-sectional data, individual states, and percent proficient metrics. Here, we analyze the Stanford Education…
