English language proficiency (ELP) assessment scores are used by states to make high-stakes decisions related to linguistic support in instruction and assessment for English learner (EL) students and for EL student reclassification. Changes to both academic content standards and ELP academic standards within the last decade have resulted in…

Many students in Title I, low-income public high schools in the Pacific southwest do not appear to have the same levels of academic mastery as their more affluent counterparts. This dissertation examines whether a classroom environment has an effect on students' perceptions of their teacher and academic achievement, and consists of a causal…

In 2006-2007, California revised its English language proficiency (ELP) assessment, the California English Language Development Test (CELDT), which resulted in more stringent criteria and higher cut scores for meeting proficiency. Using regression discontinuity designs and a difference-in-differences approach, this study examines the effects of…

English learners (ELs) are a growing demographic in schools nationwide. ELs are expected to demonstrate proficiency in core subjects like their non-EL counterparts. However, an achievement gap exists. To address the achievement disparity for ELs, schools seek certified ESOL (English to Speakers of Other Languages) teachers to provide the support…

This study reports achievement and growth from kindergarten to fourth grade for three groups of English Learners (ELs): (a) ever-ELs; (b) ELs consistently eligible for service; and (c) EL and Special Education dually-identified students. All three EL groups had lower test scores than never-ELs throughout K-4. In math, ELs grew more than never-ELs…

The current study examined the validity of curriculum-based measures (CBM) in mathematics computation (M-COMP) and oral reading fluency (R-CBM) in predicting spring mathematics and reading performance level and performance risk (>1 SD below the national mean) among students classified as English Learners (ELs). Additionally, the current study…

The authors evaluate the success of Arizona's program for English Learners (ELs) twelve years after the implementation of Proposition 203 to determine whether it meets the "third prong" test of Castañeda v. Pickard (1981), which requires a demonstration of the effectiveness of a program after its implementation. This study is a follow-up…

The problem is that translations of language in standardized mathematics tests are not provided, which reduces the achievement scores of native-Spanish-speaking English language learners (ELLs) in Grades 4 and 8. The purpose of this basic qualitative study was to explore teachers' perceptions of language translation for the National Assessment of…

Using kindergarten up to fourth-grade data from the Early Childhood Longitudinal Study (2010--2011 cohort), we investigated systematic variability in English language learners' (ELLs; n = 303) mathematics growth as well as relations of kindergarten language growth and working memory (WM) to ELLs' mathematics growth. Using growth mixture modeling,…

This mixed-method study explored the culturally responsive practices of a midsized, Southern California school district that used Expanded Learning Opportunities Program (ELOP) state funding to implement a voluntary summer program accessible to TK--6 grade students district-wide. Qualitative data gathered from semistructured interviews with the…

Difficulties faced in learning a specific mathematical vocabulary are amplified through incomplete English knowledge among students who English Language Learners (ELLs). Therefore, the present study aims to investigate the relationship between English language anxiety and the mathematical achievement of EFL/ESL students who are using EMI. Mixed…

This study investigated the stability of latent classes of students with learning disabilities among a heterogeneous sample of elementary-aged children whose first language is Spanish. To this end, children (N = 284) in Grades 1, 2, and 3 at Wave 1 (Year 1) were administered a battery of vocabulary, reading, math, and cognitive measures…

The number of English learners (ELs) who do not reclassify as English proficient after the first five years of schooling has increased in the Houston area and the state of Texas. ELs are a diverse population of students with varying levels of English proficiency. Many students who begin school as an EL reclassify as English proficient in a timely…

This study examined how attaining English proficiency and being reclassified as fluent English proficient affected achievement in English language arts and math in the first year after student reclassification in grades 3-8 in New Mexico. State policy in New Mexico bases student reclassification decisions on whether students attain a minimum…
