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…

Reclassification is a critical threshold when English Learners (ELs) exit specialized language services and access all-English mainstream classrooms. Despite the mandates of the Every Student Succeeds Act, reclassification rates and time remain a pressing problem. A product of this malfunctioning system has been long-term ELs (LTELs). This article…

California's K-12 funding and instructional policies for English learners (ELs) have changed significantly over the past 2 decades. The major policy shifts held the potential to change student learning outcome patterns for ELs. As a first step in identifying the potential impacts of these policy shifts, this report describes changes over time in…

The population of English learners (ELs) in K-12 schools continues to grow. Between the 2009-10 and 2014-15 school years, the percentage of English learners increased in over half of the states, and in 2017, English learners made up 10.1% of the total student population. Research suggests that in their transition to English, non-native speakers…

With the 2015 passage of the "Every Student Succeeds Act" (ESSA), the oversight of language policy in U.S. schools shifted from federal to state governance. Although the education of students officially designated as English learners (ELs) has historically been grounded in federal law, we argue that ELs' educational experiences are also…

New Mexico's Every Student Succeeds Act state plan set the goal for all English learner students to attain English proficiency within five years. The Regional Educational Laboratory Southwest English Learners Research Partnership conducted this study to better understand progress toward English proficiency among American Indian English learner…

This Study Snapshot highlights findings from a study that was conducted to better understand progress toward English proficiency among American Indian English learner students. The study examined two statewide cohorts of American Indian students identified as English learner students at initial kindergarten entry in 2013/14 or 2014/15 in New…

In 2006, Arizona ELL Task Force implemented Structured English Immersion (SEI) within its public schools to educate emergent bilingual (EB) students. Although prior research has demonstrated limitations of SEI, we investigate whether institutionalization has improved its implementation and outcomes using coordinators' and teachers' responses from…

The study anchors on the Linguistic research tradition of Error Analysis (EA), focused on the grammatical errors, specifically on "verb tenses" manifested in the sentences of Japanese ESL learners. The entire respondent population was drawn from the pool of registered learners in 2017 at the Clark Institute of the Philippines Foundation,…

How long does it typically take English learner students to develop English language proficiency? And how does this time vary by student characteristics such as English proficiency at entry to kindergarten, gender, and home language? The answers to these questions can provide valuable information to districts and schools. Regional Educational…

When students labeled English Learners (ELs) are reclassified as Fluent English Proficient, changes often occur in services and settings (e.g., changes in teachers, peers, and ancillary services). Policymakers play an important role in the reclassification process because they establish test-based criteria that an EL must attain in order to become…

English learners (ELs), students from a home where a language other than English is spoken and who are in the process of developing English proficiency themselves, represent over 10% of the US student population. Oftentimes education policies and practices create barriers for ELs to achieve access and outcomes that are equitable to those of their…

Properly defining a population ensures that resources, such as funding and access, meet the needs, expectations, and intended outcomes for those represented. Ethical concerns arise when a target population, such as the English Language Learner population, is defined in numerous yet incomplete ways, and differently in research and in state policies…

States participating in the four federally-funded assessment consortia are required to establish a "common definition of English Learner." This includes the two Race to the Top academic assessment consortia and the two Enhanced Assessment Grant English language proficiency (ELP) assessment consortia. This paper provides guidance that…

Across the globe, educational tests are being used at a rapidly increasing rate. More recently, educational tests are being used to inform educational policy and for holding educators accountable for student learning. One reason educational assessments are used for these important purposes is that they are considered to provide reliable and…
