Many LTELs appear fluent in English because they have mastered BICS (Basic Interpersonal Communication Skills), but they lack CALP (Cognitive Academic Language Proficiency)—the academic English necessary to succeed in high school coursework, standardized assessments, and post-secondary pathways. They need intentional instruction in academic vocabulary, discourse, grammar, and cohesion across all subject areas.
Vocabulary
Discourse Patterns
Grammatical Structures
Cohesive Devices
Challenge them with rich, rigorous content and structured language supports.
Plan collaborative, academic talk opportunities.
Integrate designated and integrated ELD.
Be explicit about how language works in your discipline.
