Opting out and remaining classified? A longitudinal study of service participation, ACCESS growth, and reclassification among high-school emergent bilinguals

This quantitative, ex post facto study examines 5 years of de-identified administrative data (2020–21 to 2024–25) from a linguistically diverse suburban U.S. high school, including 409 students officially classified as English learners (ELs). The study analyzes how ACCESS for ELLs composite scores and local reclassification records differ between students receiving specialized EL services and those whose parents refused services, with additional attention to program model, time in U.S. schools, and IEP status. The term emergent bilinguals is used to emphasize students’ multilingual repertoires, while EL is reserved for official classification and accountability contexts. Among students with Spring 2024 ACCESS scores (n = 264), most scored at WIDA Levels 2–4, and reclassification over the five-year period was uncommon, involving 26 students, or about 6%. In the consecutive-score subsample (n = 138), students receiving EL services had a mean ACCESS composite gain of +0.10, compared with −0.10 among opt-out peers, a small-to-moderate observed association (t[128] = 2.14, p = .034, d = 0.37), not a causal effect. All students reclassified in Spring 2023 or Spring 2024 were receiving EL services at exit.
