Foundations of ESL/Bilingual Education
Domain 2: Foundations of ESL/Bilingual Education
This domain covers the legal, historical, and programmatic foundations of English learner education. You need to know key court decisions, federal requirements, program models, and how ELs are identified and exited.
Legal and policy anchors
- Lau v. Nichols (1974): identical facilities do not equal equal opportunity; districts must take affirmative steps so ELs can meaningfully participate. It did not mandate a single method.
- Castañeda v. Pickard (1981): a three-part test for program adequacy - sound educational theory, effective implementation with resources, and evidence of results.
- Plyler v. Doe (1982): K–12 students cannot be denied enrollment based on immigration status.
- Title III: federal funding for language instruction and professional development; requires ELP standards, annual English proficiency assessment, and accountability.
- Program models: pull-out ESL, push-in/co-teaching, sheltered English immersion, transitional bilingual, dual-language/two-way immersion. Models vary by goal, duration, and use of L1.
Worked example
A district uses a new pull-out program but cannot show that teachers are trained or that students are progressing. Applying Castañeda: the theory may be sound, but implementation and results are weak. The district must document resources, staff qualifications, and outcome data - not just adopt a popular model.
Traps
- Believing Lau requires bilingual education; it requires meaningful access.
- Confusing Plyler (access) with Castañeda (program quality).
- Treating an ESL program as a permanent track rather than a support service.
- Forgetting that exit criteria should include evidence of academic language, not just a single test score.
