The Estimated Impact of a State English Learner Accountability and Support Policy on District and Student Outcomes in Oregon

The Estimated Impact of a State English Learner Accountability and Support Policy on District and Student Outcomes in Oregon

In Oregon, the passage of a state-level policy designed to support districts identified as struggling to support students classified as English learners (EL), House Bill (HB) 3499, created the conditions to study the combined effect of additional funding, technical assistance and accountability on EL-classified students’ outcomes. Using an event study and difference-in-differences specification, I estimate the impact of HB 3499 identification on a set of outcomes in identified districts in the first three years following policy implementation. Overall, I find that HB 3499 identification led to an increase in EL expenditures per EL-classified student at the district level. However, HB 3499 identification resulted in no significant change in the district ratio of teachers who were English for Speakers of Other Languages (ESOL) endorsed to EL-classified students. Identification also did not change the probability that an EL-classified student received bilingual services, nor result in significant changes in academic outcomes for EL-classified students in identified districts in the first three years after identification. Heterogeneity analyses suggest that the observed increase in expenditures per EL-classified students was concentrated among districts that received a less intensive intervention. Overall, findings point to a need for interventions that are larger in scope if meaningful shifts in outcomes are to be observed, although the litany of null findings may also be evidence of the longer time horizon needed to see meaningful changes in the educational environments and outcomes of EL-classified students.

Variation in Teacher Contributions to EL-Classified Students’ Performance on Standardized English Language Arts and English Language Proficiency Assessments

Variation in Teacher Contributions to EL-Classified Students’ Performance on Standardized English Language Arts and English Language Proficiency Assessments

Teacher quality is positioned as a critical element of education systems. However, studies that attempt to quantify the variation in teacher effectiveness and implications of this variation for student performance typically overlook the nuances of EL education that likely impact conclusions about teachers’ roles in shaping EL-classified students’ educational outcomes. Specifically, the provision of additional instruction on the English language is not explicitly addressed in examinations of teachers’ unique contributions to EL-classified students’ academic performance, nor do examinations of teacher contributions to student outcomes include English language proficiency as an outcome. Addressing these gaps can inform our conceptual understanding of how different sources of instruction throughout the education process contribute to variability in measured academic and linguistic performance among EL-classified students. In this study, using statewide data for Oregon EL-classified students who are in grades 6-8 and enrolled in both an English language development (ELD) and English language arts (ELA) class, I explored the extent to which variation is measured across ELA and ELD teachers in their contributions to EL-classified students’ performance on ELA and ELP assessments. I find that variation in both ELA and ELD teachers' instructional effectiveness, as proxied through changes in students' test scores, has implications for EL-classified students' ELA and English language proficiency performance. The variation is larger for teachers' own subject. This highlights the important role that content and language teachers play in supporting EL-classified students language and literacy development.
