A growing body of evidence challenges a long-held practice in American K-12 education: the segregation of English learners (ELs) into separate classrooms. New research indicates that, contrary to common assumptions, grouping ELs together often yields no academic benefits and, in some cases, can actively hinder their progress, particularly in high school. This revelation is prompting educators and policymakers to re-evaluate strategies for supporting students acquiring English proficiency.
The Persistent Practice of Segregation and Its Questionable Benefits
For decades, schools have routinely grouped English learners together, often driven by logistical constraints – limited bilingual staffing and the desire to provide focused language instruction. The intention, while well-meaning, has consistently outpaced empirical support. Despite the widespread adoption of this practice, concrete evidence demonstrating its effectiveness has remained elusive. Now, two recent studies are adding significant weight to the argument that separate is not equal when it comes to English language acquisition.
High School Outcomes: A Concerning Trend
A study published in the Peabody Journal of Education examined the academic trajectories of over 31,000 English learners in New York City public schools. Researchers categorized students based on their years of English language learning – newcomers (1-3 years), developing learners (4-6 years), and long-term learners (7+ years). The analysis revealed a consistent pattern: higher concentrations of ELs in core academic courses were associated with significantly lower rates of high school graduation and college enrollment. Specifically, students in highly concentrated EL courses were 10-15% less likely to graduate within four years, and 12-13% less likely to enroll in college immediately after graduation.
“Many educators are navigating complex staffing and scheduling challenges,” explains Kristin Black, a research scientist at New York University Steinhardt. “However, our findings suggest a need for caution. While further research is needed to identify specific EL populations who might benefit from segregated instruction, the current evidence points towards a potentially detrimental effect for many students.”
Elementary School Findings: Nuance and Heterogeneity
Complementing the high school study, research in the American Education Research Journal investigated the impact of homogenous versus heterogeneous grouping in elementary school EL classrooms. Researchers found no significant differences in overall academic outcomes for the average student. However, a subtle but important distinction emerged: heterogeneous groups appeared to benefit students with stronger English language skills, while homogenous groups showed some advantages for those at earlier stages of language acquisition.
“We observed that teachers in heterogeneous groups tended to employ more open-ended questioning and foster richer classroom discussions,” notes Michael Kieffer, a professor at NYU Steinhardt and lead author of the AERJ study. “This suggests that the dynamic interaction within mixed-ability groups can be particularly beneficial for students who are already developing their language skills. At the same time, targeted instruction within homogenous groups may provide crucial support for newcomers.”

These findings align with a broader trend in educational research that questions the automatic assumption that segregating students based on language proficiency is the most effective approach. The studies underscore the importance of considering the individual needs of each student and creating inclusive learning environments that promote interaction and collaboration between ELs and their English-proficient peers.
What role should teacher training play in preparing educators to effectively integrate ELs into mainstream classrooms? And how can schools address the logistical challenges of providing appropriate support without resorting to segregation?
Further research is needed to explore the specific conditions under which certain ELs might benefit from targeted instruction in segregated settings. However, the current evidence strongly suggests that the default practice of separating English learners should be re-evaluated and replaced with more inclusive and integrated approaches.
