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.
