The Effects of English Learner Status on Special Education Placement  \nAUTHORS  \nMark Murphy  \nUniversity of Hawai`i at Mānoa  \nAngela Johnson  \nNWEA  \nABSTRACT  \nThis 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 seven years. Our regression discontinuity estimates consistently differ substantively from results generated through regression analyses. We find evidence that the effect of EL status on SPED placement was either null or tied to slight under-identification. Our results suggest that under-identification occurred two years after EL classification. We also find that EL status led to under-identification for Spanish speakers and proportionate representation for  \nMandarin/Cantonese speakers and speakers of all other languages.  \nAcknowledgements-We are grateful for the collaborative efforts of our partner school district and all participating staff.

When such services meet students’ needs for linguistic or disability support, indicators of student success can improve (Berkeley et al., 2010; Morgan et al., 2010; Wang & Lam, 2017) .  \nConversely, when student needs are unmet, student success can falter (Morgan et al., 2010) . Persistent achievement gaps between student populations who are eligible for accommodationsand those who are not suggest that there is substantial room for improvement nationwide (Albus et al., 2013; Pasternack, 2014) . Furthermore, some students rely not solely on English Learner (EL) services or Special Education (SPED) services, but rather on supports for both a learning disability and developing English proficiency. We refer to these students as dually identified students (i.e., identified for both EL and SPED) and they are a central focus of this study (Carnock & Silva, 2019; Umansky et al., 2017) .  \nDespite a substantive body of descriptive and qualitative research on the relation between EL and SPED placement, little is known about the causal link between the two. Prior work has highlighted disproportionate representation of EL students in SPED using descriptive regression and hazard analyses (Morgan et al., 2015, 2017, 2018; Umansky et al., 2017) . This work has most frequently found EL students to be under-identified in elementary grades, but overidentified in secondary grades (Umansky et al., 2017) .
