In the context of policy-driven language testing for citizenship, a growing body of research examines the political justifications and ethical implications of language requirements and test use. However, virtually no studies have looked at the role that language testers play in the evolution of language requirements. Critical gaps remain in our…

Most states responded to the onset of the pandemic by temporarily granting teachers Emergency licenses. These licenses allowed teachers to work in classrooms without passing the typical licensure exams. Since then, several states have extended their use of Emergency licenses, raising questions about how these policies impact the composition of the…

This study investigates the impact of various types of absenteeism--excused, unexcused, and suspensions--on 2024 English I and II EOC scores among 9th and 10th graders at a suburban North Texas high school. This quantitative analysis aimed to understand whether different absence types influence academic achievement when controlling for ethnicity…

This study contributes to a growing body of scholarship at the intersection of bilingual education and education policy and examines reclassification, or the transition out of formal English language services in schools, as one potential lever in accelerating or decelerating multilingual learners' science learning. More specifically, it traces…

Group differences in test scores are a key metric in education policy. Response time offers novel opportunities for understanding these differences, especially in low-stakes settings. Here, we describe how observed group differences in test accuracy can be attributed to group differences in latent response speed or group differences in latent…

Sometimes a treatment, such as receiving a high school diploma, is assigned to students if their scores on two inputs (e.g., math and English test scores) are above established cutoffs. This forms a multidimensional regression discontinuity design (RDD) to analyze the effect of the educational treatment where there are two running variables…

Multilingual learners (MLs) represent an increasing proportion of public school students. Although much attention has been given to their academic performance in English language arts and math, less research has addressed their academic performance in science, particularly in elementary school. This study leveraged nationally representative data…

This paper develops a new measure of human capital, calculated as a cohort-weighted average of the quality of education (PISA scores) and the quantity of education (mean years of schooling). Contrary to the existing studies, the relative weights of quality and quantity are estimated (and not calibrated). The quality of education is estimated to be…

This study estimates the effect of between-class ability grouping on Chilean secondary students' academic achievement. We rely on a structural feature of the school system: A considerable number of students who complete primary school must change schools to start their secondary education. Cardinality matching was performed to account for…

Test-optional admissions policies have been steadily, though slowly, expanding throughout higher education institutions for decades. The COVID-19 pandemic, however, sparked a rapid expansion of institutions adopting test-optional policy. Using a diffusion of innovations framework, this study assesses the institutional characteristics that shaped…

In the neoliberal economic policies adopted by nations, services for social welfare including education are rendered commodities to be purchased by citizens, and the employees' (teachers') skills too get commodified. The pedagogical skills of teachers may often be judged predominantly in terms of their contribution towards ease of profit-making by…

The purpose of this dissertation was to scrutinize the complexities involved in the formulation and implementation of relevant policies. The design of each study mirrored key elements in the legislative life cycle specifically as it pertained to civics education policymaking, including problem identification, policy creation, and policy diffusion.…

I study student characteristics and academic performance at the University of California, where consideration of an applicant's ethnicity has been banned since 1996 and SAT scores were used in admitting students to the university until fall 2021. I show the following: (1) SAT scores were more important than high school grades in predicting…

Automatic enrollment is a straightforward education reform that facilitates both educational excellence and equity in K-12 schools. By automatically placing highly qualified students in advanced coursework, this low-cost, bi-partisan strategy creates opportunities for high achievement for all students, with low-income, rural and small town, and…

International surveys are increasingly being used to understand nonacademic outcomes like math and science motivation, and to inform education policy changes within countries. Such instruments assume that the measure works consistently across countries, ethnicities, and languages--that is, they assume measurement invariance. While studies have…
