COMMON CORE TIER VOCABULARY INFORMATION
Common Core State Standards: Focus on Tier 2 & Tier 3 Academic Vocabulary
The new Common Core State Standards for reading and English language arts are three standard
deviations above many States passing cut scores (NCLB testing mandate). A (CCSS) white paper to
publishers and curriculum developers states a greater focus on Tier 2 high frequency academic
vocabulary is needed in the primary grades. Teachers will have a few years to learn and prepare before
the new standards are in effect and part of high stakes testing. Preparing students is the proverbial fly in
the ointment, meeting the challenge will be virtually impossible to reach in the time allotted. What next?
Endless teacher in-service training?
I have used variations of Tier 2 high frequency academic vocabulary plus the NWEA tier 3 academic
content specific vocabulary for years, but I have never found a qualitative graded tier 2 list! You will find
great tier 3 vocabulary list by frequency, grade level, and content but not tier 2 vocabulary by grade level.
I will bring more resources when I develop or find them.
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.
