Which type of words are classified as Tier One Words?

Tier One words are characterized as high-frequency words that are commonly used in everyday speech. These words are typically part of a student’s oral vocabulary and are accessible to most children without the need for specialized instruction. They encompass basic, everyday language that one would encounter in a variety of contexts, making them essential for effective communication at a fundamental level.

While content-specific vocabulary refers to words related to particular subjects, complex academic terms involve specialized language used in academic settings, and advanced literary words are often found in literature and may require a higher level of comprehension, none of these categories adequately describe Tier One vocabulary. Tier One words serve as the foundation of language acquisition and literacy development, making them crucial for young learners as they establish their language skills.
