COMMON CORE TIER VOCABULARY INFORMATION
Common Core State Standards: Focus on Tier 2 & Tier 3 Academic Vocabulary
Tier 1 Basic words that commonly appear in spoken language. Because they are heard frequently in numerous contexts and with nonverbal communication, Tier 1 words rarely require explicit instruction.Examples of Tier 1 words are clock, baby, happy and walk.
Tier 2 High frequency words used by mature language users across several content areas. Because of their lack of redundancy in oral language, Tier 2 words present challenges to students who primarily meet them in print. Examples of Tier 2 words are obvious, complex, establish and verify.
Tier 3 Words that are not frequently used except in specific content areas or domains. Tier 3 words are central to building knowledge and conceptual understanding within the various academic domains and should be integral to instruction of content. Medical, legal, biology and mathematics terms are all examples of these words.
