Introduction: Increasing evidence has shown that student mobility is negatively correlated with individual students' and schools' academic performance (Hanushek, Kain, & Rivkin, 2004; Lara, Mizala, & Repetto, 2011; Sun & Pan, 2014). However, the negative impact may be due to the switching behavior or it could be only a side effect of…

Background/Context: Increasing evidence suggests a connection between racial differences in rates of exclusionary discipline (suspensions/expulsions) and academic achievement by (Losen & Martinez, 2020; Reardon et al., 2018). Black students receive out-of-school suspensions and expulsions at disproportionately higher rates, which is associated…

Background/Context: A minority of U.S. eighth graders reach the proficient level on the National Assessment of Educational Progress (U.S. Department of Education, 2021). Early evidence suggests that the pandemic has made things worse, especially so for underserved student populations (Lewis et al., 2021). Math proficiency is central to advanced…

The Cleveland Metropolitan School District (CMSD) has seen the number of English learner students in grades K-12 increase in recent years, even as overall enrollment has decreased. In addition, the English learner student population has grown more diverse in race/ethnicity, country of origin, and native language. The increasingly diverse English…

Ethnoracial inequality in educational achievement and attainment is a long-standing feature of the American education system. For example, national reading assessments show that White fourth graders scored nearly a standard deviation higher than Black or Hispanic students on average in 2015 (NCES, 2015). The measurement and analysis of differences…

The information provided in this report shows how students perform when they repeat algebra I and how the level of improvement varies depending on initial course performance and the academic measure (course grades or CST scores). This information can help inform decisions and policies regarding whether and under what circumstances students should…

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…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

To raise math success rates in middle school, many schools and districts have implemented summer math programs designed to improve student preparation for algebra content in grade 8. However, little is known about the effectiveness of these programs. While students who participate typically experience learning gains, there is little rigorous…

The Wake County Public School System (WCPSS) in North Carolina recently addressed the issue of advancement in and equitable access to advanced mathematics. Under a recent policy, WCPSS uses a SAS-generated predicted probabilities of students' success in obtaining a passing score on the NC Algebra I End-of-Course (EOC) exam, to determine…

The effect of student mobility on student outcomes has garnered much attention by researchers and policy-makers over the past few decades. The extant research relies on annual tests, typically measured each spring, to estimate the effect of structural moves on student achievement. The current literature does not allow researchers to evaluate…

This work summarizes the results of two randomized control trails (RCTs) aimed at evaluating the effectiveness of a professional development program for lower secondary school math teachers. The program, called [email protected], was financed by the Ministry of Education in Southern Italy with EU funds. It lasts a full school year and it is based on formal…

In 2008, the California State Board of Education voted to require all students to enroll in algebra by 8th grade. This policy initiative, yet to be actually implemented, represents the culmination of a decades-long movement toward offering algebra instruction before the traditional high school years. Nationally, the proportion of 8th grade…

This study seeks to demonstrate a method for treatment effect estimation in a multisite observational study where the treatment is highly selective and the assignment mechanism varies across sites. The method is demonstrated by addressing three primary research questions about the effect of 8th grade algebra: (1) For students who take algebra in…

Attendance is probably the most fundamental behavioral indicator of student engagement with school. Though many students fall off-track to success for the first time in ninth grade, poor attendance patterns often begin increasing in middle school and become worse in high school. Missing school during the secondary grades can often be traced to low…
