Page last updated: February 7, 2026 • Reviewed by Maria Santos, M.A. TESOL

English Language Learners (ELLs) — also known as English Learners (ELs), Limited English Proficient (LEP) students, or Multilingual Learners (MLs) — represent the fastest-growing student population in U.S. public schools. As of 2025, approximately 5.3 million students (10.4% of public school enrollment) are classified as ELLs. This population has grown by 28% over the past decade. Every classroom teacher is, by necessity, a language teacher.

Legal Requirements

Federal and state laws require schools to provide specific services to ELLs:

Law/CaseYearKey Requirement
Title VI of the Civil Rights Act1964Prohibits discrimination based on national origin, including language
Lau v. Nichols (Supreme Court)1974Schools must take affirmative steps to provide ELLs access to meaningful education
Equal Educational Opportunities Act1974Schools must overcome language barriers that impede equal participation
Castañeda v. Pickard (5th Circuit)1981Three-part test: ELL programs must be (1) based on sound educational theory, (2) implemented with adequate resources, and (3) evaluated for effectiveness
Every Student Succeeds Act (ESSA)2015ELP standards, annual ELP assessment, accountability for ELL progress, reporting requirements

Language Proficiency Levels

The WIDA (World-Class Instructional Design and Assessment) framework is used in 41 states to define English language proficiency levels:

LevelLabelDescriptionClassroom Indicators
1EnteringKnows and uses minimal social and academic EnglishPoints, draws, gestures; uses single words; copies text; limited comprehension
2EmergingBegins to use general and some specific languageUses phrases and short sentences; participates in structured activities; recognizes main ideas
3DevelopingDeveloping general and some specific languageUses simple sentences; participates with support; identifies details; writes short paragraphs
4ExpandingUses general and specific language with increasing complexityUses complex sentences; participates more independently; reads grade-level text with support
5BridgingUses specialized academic language at or near grade levelCommunicates effectively in academic settings; approaching proficiency; needs minimal support
6ReachingReaching grade-level academic English proficiencyFully participates in grade-level instruction without ELL-specific support

Instructional Models for ELLs

ModelDescriptionProsCons
Sheltered English Instruction (SEI) Content taught in English with scaffolding and language support Develops academic English rapidly; integrates content and language May not fully develop native language; high cognitive load
Dual Language/Two-Way Immersion Instruction in two languages (50/50 or 90/10 model) with native English and ELL students together Develops bilingualism and biliteracy; high academic outcomes; promotes cross-cultural understanding Requires bilingual teachers; needs balanced enrollment; multi-year commitment
Transitional Bilingual Initial instruction in native language, gradually transitioning to English over 2-3 years Builds on native language strengths; smoother transition Native language use decreases over time; "early exit" models may be too rapid
Pull-Out ESL ELLs leave general education classroom for dedicated English language instruction Focused language instruction; small group setting Students miss content instruction; potential stigma; isolated from peers
Push-In/Co-Teaching ESL specialist co-teaches in the general education classroom ELLs stay in gen ed; ESL and content integrated; collaboration between teachers Requires strong co-teaching relationship; scheduling challenges

Sheltered Instruction Observation Protocol (SIOP)

SIOP is the most widely researched sheltered instruction model. It includes 30 features organized into 8 components:

ComponentKey Features
1. Lesson PreparationContent and language objectives; grade-appropriate content; supplementary materials; meaningful activities
2. Building BackgroundConnect to students' experiences; link to prior learning; emphasize key vocabulary
3. Comprehensible InputAppropriate speech rate; clear explanations; variety of techniques (visual, gestural, verbal)
4. StrategiesScaffolding; promote higher-order thinking; use cognitive and metacognitive strategies
5. InteractionFrequent opportunities for interactions; grouping configurations; wait time; native language support
6. Practice & ApplicationHands-on materials; activities integrating language skills; apply content/language knowledge
7. Lesson DeliveryObjectives supported; students engaged; appropriate pacing
8. Review & AssessmentComprehensive review; regular feedback; assessment of objectives

Classroom Strategies for All Teachers

Making Content Comprehensible

Scaffolding Writing for ELLs

Proficiency LevelWriting Scaffolds
Level 1-2 (Entering/Emerging)Labeled diagrams, word banks, cloze sentences, copied phrases with illustrations, graphic organizers
Level 3 (Developing)Sentence frames, paragraph templates, word banks with academic vocabulary, mentor texts with annotations
Level 4 (Expanding)Essay outlines, transition word lists, peer revision with targeted checklist, rubric with language criteria
Level 5 (Bridging)Grade-level writing expectations with access to bilingual dictionary, self-editing checklist for common errors
