Teacher Autonomy, Collaboration, and Shared Responsibility Help English Learners Succeed in New York City High Schools
English learners in high schools—especially newly arrived immigrant students—often face a long list of challenges. They must catch up academically, adapt to a new culture, and learn a new language at the same time. A recent study from New York University takes a close look at what actually helps these students thrive, and the findings point strongly toward three professional conditions inside schools: teacher autonomy, teacher collaboration, and collective responsibility.
Instead of focusing solely on classroom instruction or language-learning programs, the researchers examined how school-wide professional culture shapes outcomes for English learners. Their approach is based on a mixed-methods study conducted across multiple years and multiple data sources, and the results offer a very clear message: the environment teachers work in directly affects student success, especially for English learners.
Understanding the Purpose of the Study
The research team from NYU Steinhardt wanted to fill an important gap in the existing body of work. A large portion of prior studies on English learners, often referred to as ELs, looks primarily at instructional methods or language-acquisition policies. There is far less work examining how a school’s professional environment—how teachers work, plan, collaborate, and advocate—affects these students’ academic performance.
To address this, the researchers examined high schools within the Internationals Network for Public Schools, a network designed specifically for recently arrived immigrant students. All ninth-grade students in these schools have typically lived in the United States for four years or less.
The research team conducted a two-part study to understand not just what the best-performing schools were doing, but whether those practices, when examined across the broader New York City school system, consistently correlated with better academic outcomes.
Part 1: Examining Two Top-Performing Schools
The first part of the study focused on two New York City high schools that showed the strongest gains in credits earned versus credits attempted among immigrant English learners. Between 2018 and 2020, the researchers collected extensive data, including:
- classroom observations
- teacher meeting observations
- school-level documents
- interviews with educators
- focus groups with students and staff
After analyzing these materials, the team identified three key conditions that were consistently linked with better academic performance among English learners:
- Teacher influence and autonomy
Teachers had significant control over curriculum decisions and professional development. This freedom allowed them to create culturally meaningful lessons and to support multilingual learning in ways that rigid, top-down structures often prevent. - Deep teacher collaboration
Teachers collaborated across grade levels and across subjects. This wasn’t occasional teamwork—it was continuous, structured collaboration embedded into the school’s daily operations. - Collective responsibility
Teachers and staff shared a unified mission centered on supporting immigrant students academically and emotionally. This included active advocacy, shared problem-solving, and a consistent belief that every student could succeed.
These conditions created an environment where English learners felt supported, understood, and academically challenged. They also empowered teachers to address students’ unique needs more effectively.
Part 2: Testing the Findings Across NYC Schools
The second part of the research used two large datasets to see whether these same three conditions showed correlations with better student outcomes across many more schools:
- the 2012 New York City Learning Environment Survey, where teachers, parents, and administrators rated aspects of school culture
- New York City administrative data on student credit attainment
Unlike the first part, which focused only on newcomer immigrant schools, this portion analyzed NYC high schools in general, including those with lower or higher percentages of English learners.
The results strongly reinforced the findings from the two case-study schools. All three conditions—teacher autonomy, peer collaboration, and collective responsibility—were positively associated with student success. But the most important takeaway was this:
The positive effects were strongest in schools with the highest proportions of English learners.
A particularly striking example comes from peer collaboration. In schools with an average share of English learners, teachers working in the most collaborative environments had students with credit-attempt-to-credit-attainment ratios about 10 points higher than those in the least collaborative schools.
But in schools with the highest number of English learners, the difference grew to 23 points, more than twice as large.
The same amplified effect appeared with teacher autonomy and collective responsibility. In other words, while these factors help all students, English learners benefit the most when teachers work in a strong professional culture.
Why These Findings Matter
This study’s results matter for two major reasons:
- They broaden the conversation around English learner support.
EL success isn’t only about grammar instruction, vocabulary development, or language-learning programs. While those are important, this research shows that deeper professional factors—how teachers collaborate, how much decision-making power they have, and how committed the whole school is to immigrant youth—can significantly influence student success. - They highlight scalable practices.
Teacher autonomy, collaboration structures, and shared responsibility are conditions that any school can work toward. They aren’t restricted to specialized networks or unique school models.
Given that ELs are one of the fastest-growing populations in U.S. public schools, understanding the broader structures that support them is crucial.
Additional Insight: Why Professional Culture Matters for English Learners
To deepen the discussion for blog readers, it’s helpful to explore why these conditions have such a strong impact.
Why Teacher Autonomy Helps
English learners often come from diverse cultural and linguistic backgrounds. When teachers have autonomy, they can:
- include students’ cultural experiences in lessons
- tailor assessments
- adapt materials
- integrate multilingual strategies
Autonomy gives educators room to meet students where they are.
Why Collaboration Improves Outcomes
Collaboration prevents students from falling through the cracks. English learners benefit when:
- subject-area teachers coordinate with language-support teachers
- teachers share insights about individual student needs
- interdisciplinary units reinforce both content and language
When teachers work in isolation, ELs face inconsistent expectations and fragmented support.
Why Collective Responsibility Is Essential
English learners frequently face:
- unfamiliar academic systems
- new cultural expectations
- language barriers
- social adjustment challenges
A school culture where every adult believes in each student’s potential—and acts on that belief—creates the stability and encouragement students need to succeed.
How the Internationals Network Fits In
The schools examined in the first phase belong to the Internationals Network for Public Schools, a model that has long focused on:
- heterogeneous classrooms
- project-based learning
- language development across the curriculum
- supportive newcomer environments
This study provides fresh evidence reinforcing the network’s approach. It also suggests that even schools outside the network can benefit by adopting similar conditions.
Final Thoughts
This study offers one of the clearest explanations of how school-level professional culture affects immigrant English learners. It also shows that improvements in teacher autonomy, collaboration, and collective responsibility don’t just help ELs—they help all students, with even greater benefits for those learning English.
The takeaway is simple: supporting teachers is one of the most effective ways to support immigrant students.
