Recent data from statewide assessments, scores on the National Assessment of Educational Progress (NAEP), and college remediation needs show that an increasing number of K-12 students are not performing at grade level. As schools look to support these students' learning, some districts are turning to a proven strategy for identifying the students…

This study explored the effectiveness of extended time (ET) accommodations in the 2017 NAEP Grade 8 Mathematics assessment to enhance educational equity. Analyzing NAEP process data through an XGBoost model, we examined if early interactions with assessment items could predict students' likelihood of requiring ET by identifying those who received…

This essay provides a two-pronged critical assessment of a subset of the literature on racial disproportionality in special education: that which aims to estimate racial disparities among otherwise similar children. This body of research has shown that Black students are less likely than "comparable" White students to receive special…

K-12 gifted and talented programs have struggled with racial, ethnic, socioeconomic, native language, and disability inequity since their inception. This inequity has been well documented in public schools since at least the 1970s and has been stubbornly persistent despite receiving substantial attention at conferences, in scholarly journals, and…

In high-stakes, large-scale, standardized tests with certain time limits, examinees are likely to engage in either one of the three types of behavior (e.g., van der Linden & Guo, 2008; Wang & Xu, 2015): solution behavior, rapid guessing behavior, and cheating behavior. Oftentimes examinees do not always solve all items due to various…

This study uses the overlap sample of about 3,500 students who participated both in the High School Longitudinal Study of 2009 (HSLS:09) and the 2013 Grade 12 National Assessment of Educational Progress (NAEP) mathematics assessment to investigate how mathematics motivation (mathematics identity, mathematics self-efficacy, and mathematics…

We used time-varying effect modelling of two very large samples of fourth-grade students (N[subscript reading] = 148,240, N[subscript mathematics] = 152,220) to investigate associations between adoption and over-time implementation of a de facto cap on special education service receipt and over-time likelihoods of disability identification from…

Background/Context: Regression discontinuity (RD) designs are used for policy and program evaluation where subjects' eligibility into a program or policy is determined by whether an assignment variable (i.e., running variable) exceeds a pre-defined cutoff. Under a standard RD design with a continuous assignment variable, the average treatment…

Whether students of color are more or less likely to be identified as having disabilities than similarly situated students who are White in U.S. states with histories of de jure and de facto racial segregation is currently unknown. Unadjusted analyses of large samples of students attending elementary and middle schools in the U.S. South yielded…

Third grade is a critical checkpoint in a child's educational journey. By the end of third grade, children need literacy skills that prepare them for increasing curriculum demands in fourth grade and beyond. Students who are not reading on grade level by this point are significantly more likely to drop out of high school or fail to graduate on…

As the United States continues to grow and the composition of its population shifts, expanding opportunity and reducing barriers to education must be a national priority. An essential first step toward greater educational equality is a deeper understanding of the fundamental changes in the demographic composition of the nation. Consider, for…

Federal legislation and policy increasingly seek to address minority overrepresentation in special education due to concerns that U.S. schools are misidentifying children as disabled based on their race or ethnicity. Yet whether and to what extent this is occurring is currently in dispute. We estimated racial disparities in disability…

The number of economically vulnerable students in the United States is large and growing. In this article, we examine income-based excellence gaps and describe recent controversies in the definition and measurement of poverty, with an eye toward their application to gifted education and meeting the needs of talented, economically vulnerable…

The identification of gifted and talented students and the accompanying fact that most identification systems result in the underrepresentation of students from African American, Hispanic, Native American, English language learning, and low-income families are two of the most discussed and hotly debated topics in the field. This article provides…

There have been numerous calls to increase quantitative studies examining the role of culturally responsive schooling (CRS) on American Indian and Alaska Native (AIAN) achievement. The National Indian Education Study (NIES) is the only large-scale study focused on (AIAN) students' cultural experiences within the context of schools. Given that…
