Various stakeholders, such as policymakers and educators, require diagnostic feedback and actionable test results. One particular context in which fine-grained test results are of utmost importance is English language proficiency (ELP) assessments as they are used for critical decisions for students. Diagnostic classification models (DCMs) afford…

Using a large sample of longitudinal assessment data from children in publicly funded infant/toddler care, preschool, and kindergarten (analytic N = 453,468), this study modeled language and literacy trajectories from early infancy through kindergarten for dual language learners (DLLs) from homes representing many different languages and their…

We examined the relation of morphological awareness with language and literacy skills, namely phonological awareness, orthographic awareness, vocabulary, word reading, spelling, text reading fluency, and reading comprehension. We also examined potential moderators of the relations (grade level, orthographic depth of language, receptive vs.…

Purpose: The purpose of this quantitative, causal-comparative study was to determine whether English learners who participated in transitional kindergarten perform equally or better than English learners who did not participate in transitional kindergarten in the areas of oral language, written language, and overall language as measured by the…

Purpose: The differential diagnosis of developmental language disorder (DLD) in bilingual children represents a unique challenge due to their distributed language exposure and knowledge. The current evidence indicates that dual-language testing yields the most accurate classification of DLD among bilinguals, but there are limited personnel and…

Bilingual children with a limited command of the second language (L2) often yield unsatisfactory results in L2-based non-word repetition tasks (NWRT) for the assessment of working memory. In this study, monolinguals (MO) and bilinguals (BI) of preschool age acquiring German were compared in regard to their performance on German-based NWRT to…

Children with Developmental language disorder (DLD) have particular difficulty learning language despite otherwise general normal development. When school age bilingual children struggle with language, a common question is if the difficulties they present reflect lack of ability or lack of language experience. To address the question of…

Background/Context: This paper reports the process, progress, and initial findings from a systematic review of research on English learner (EL) reclassification in the United States. EL classification is federally protected status in U.S. public schools that identifies students whose core rights must be met to support their educational access (Lau…

This study examines the effects of English Learner (EL) status on subsequent Special Education (SPED) placement. Through a research-practice partnership, we link student demographic data and initial English proficiency assessment data across seven cohorts of test takers and observe EL and SPED programmatic participation for these students over…

The purpose of the present study was to examine the predictive value of a dynamic test of English and French lexical specificity on at-risk reading classification in 13 at-risk and 44 not at-risk emerging English (L1)-French (L2) bilingual Grade 1 children (M = 75.87 months, SD = 3.18) enrolled in an early French immersion program in Canada.…

The purpose of this study was to examine how classroom language contexts characterized by peer language skills and proportions of dual language learners (DLL) influenced English language development for DLL and non-DLL children. Participants were 2,131 children from 135 classrooms across preschool through Grade 3. Children were classified into…

Using student-level longitudinal data from one large urban school district, I examine Long-term English Learners' (LTELs) characteristics and their linguistic and academic performance in comparison to on-track English learners and initially fluent students. I also investigate what factors are related to their becoming LTELs. This study focuses on…

This three-article dissertation examined how policy choices in three key policy areas -- initial enrollment, service provision, and reclassification -- impact English learner (EL)-classified students. The first article examined the national landscape of state statutes, regulations, and state education agencies' (SEA) guidance that support…

This article maintains that in spite of their seeming progress, Mexican-origin students in the US continue to face barriers that are typical of the complex challenges endured in public schools by minoritized and racialised peoples in the American context. It begins with a brief overview of the current-day demographics of the Mexican-origin…

The development of academic English proficiency and the time it takes to reclassify to fluent English proficient status are key issues in English learner (EL) policy. This article develops a shared random effects model (SREM) to estimate English proficiency development and time to reclassification simultaneously, treating student-specific random…
