Abstract

Across U.S. classrooms, the rise of scripted and tightly structured curriculum programs has created a new instructional norm, driven by accountability pressures, policy mandates, and efforts to close achievement gaps. While these programs promise coherence, equity, and reliability, teachers particularly those working with English Language Learners (ELLs) and Culturally and Linguistically Diverse (CLD) students often experience professional disempowerment, as rigid adherence to scripts can conflict with research-based principles of culturally responsive and developmentally appropriate instruction. This chapter explores the tension between curriculum fidelity and instructional flexibility, framing it as a pedagogical, ethical, and professional challenge rather than a purely technical issue.
