Evaluating students from culturally and linguistically diverse backgrounds (i.e., emergent bilinguals) presents challenges to evaluation teams, as distinguishing between a language disorder and typical second language development is more complex. The skills and knowledge required to do this task often exceed the level of training that evaluators…

This dissertation consists of three empirical studies that explore the educational experiences and trajectories of English learners (ELs) and students with disabilities. The first study uses longitudinal data from four large California school districts to examine the characteristics of long-term ELs (LTELs) and former ELs--those reclassified as…

Given the literature review on over and under representation of ELL students in Special Education, this research aimed to study how teachers identify between ELL students who present with language proficiency learning difficulties and students who might exhibit learning disabilities. This qualitative study added to existing literature on…

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…

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…

Students with and without learning disabilities often struggle to learn a foreign language (FL). Teachers could benefit from a measure designed to screen and identify students at risk for FL learning difficulties. In this study, we examined the reliability and validity of scores from four curriculum-based measures (CBM) as potential indicators of…

Ongoing research has demonstrated that culturally and linguistically diverse (CLD) students may be disproportionately represented among students with learning disabilities (LDs). The main aim of this research was to identify groups of CLD students at risk for LDs using the achievement criterion. To that end, 158 students participated in the…

Overrepresentation of Dual Language Learners (DLLs) in special education remains a problem even after 40 years of inquiry. One factor is that the U.S. federal government has neither clearly explained the definition of Specific Learning Disability (SLD) nor operationally defined it to identify children for special education services. This lack of…

The evaluation of minority children for special education by law should be nondiscriminatory. To be in compliance with federal mandates such as the Individuals with Disability Education Act (IDEA), No Child Left Behind (NCLB), and Public Law 94-142, minority children who are also English language learners (ELLs) should be assessed in their native…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

Identifying which K-12 English Learners (ELs) should receive special education services has historically been challenging and fraught with error. Educators are commonly puzzled as to whether an EL student's academic difficulties are the result of insufficient academic English language, inappropriate instruction, or an intrinsic learning…

Data from three interrelated studies of English Language Learners who were identified as having reading-related learning disabilities suggest that the majority of participants were misclassified. Bilingual education teachers and other educational professionals had difficulty distinguishing students for whom special education referral was…

This study explores No Child Left Behind's required timetable for English language learners (ELLs) to reach English language proficiency within five years, as outlined in the Annual Measurable Achievement Outcomes (AMAOs), despite the lack of research evidence to support this as a reasonable expectation. Analysis was conducted on the archived data…

This article explores why students with learning disabilities and attention deficit hyperactivity disorder (AD/HD) struggle with the foreign language curriculum and how their difficulties manifest themselves in the classroom setting. Findings of a three-year, federally funded study that sought to combine expertise in the field of learning…

This publication explores issues and makes recommendations related to meeting the needs of English learners with limited language proficiency or learning disabilities, or both. The authors begin by noting the current federal policy context in which this discussion of reading instruction and interventions for English language learners (ELLs)…
