About the Study The Problem

Dual-language programs are designed to advance bilingualism, biliteracy, academic achievement, and sociocultural competence. Yet the integrity of these programs can weaken when implementation decisions are shaped by staffing constraints, accountability pressures, inconsistent expectations, limited monitoring systems, or adaptations that move schools away from the original vision of the program.

Why Program Integrity Matters

Program integrity refers to the degree to which a dual-language program is implemented in ways that remain aligned to its intended purpose, design, equity commitments, and language-development goals. When program integrity is not protected, multilingual learners may experience reduced access to rigorous bilingual instruction, inconsistent language allocation, weakened biliteracy pathways, or fragmented supports across classrooms and grade levels.

The Central Challenge

Schools often make practical decisions in response to real conditions. Leaders may need to respond to teacher vacancies, enrollment shifts, curriculum changes, parent expectations, assessment pressures, or district-level priorities. Some adaptations are necessary and appropriate. Others can create program drift when they weaken the core features of dual-language education.

The challenge is not simply whether schools adapt. The challenge is determining which adaptations preserve the integrity of the program and which changes undermine equity, coherence, and multilingual learner access.

What This Study Examines

This study examines how dual-language program integrity is protected, challenged, monitored, and sustained across school, network, and district contexts. It focuses on the leadership decisions, implementation conditions, accountability structures, and support systems that influence whether dual-language programs remain coherent and equitable over time.

Guiding Concern

How can school and district leaders distinguish between necessary adaptation and harmful program drift while protecting equitable outcomes for multilingual learners?
