What type of words does Tier 1 refer to?

Tier 1 words consist of everyday vocabulary that is commonly used in conversational language. These words are typically learned through everyday experiences and interactions, making them familiar to most individuals, including those who are English language learners. They are the basic building blocks of language and include simple words often used in day-to-day communication, such as "house," "cat," "run," or "happy."

By focusing on Tier 1 words, educators can help students become comfortable with language they encounter frequently, facilitating better communication skills. In contrast, the other options refer to specialized vocabulary that may not be encountered as regularly in casual conversation and can be more complex in nature. Academic words and technical jargon, for example, involve specific terminology that may require deeper understanding or context, while cross-discipline words span multiple subjects but are not necessarily part of everyday speech. Understanding Tier 1 words is crucial for fostering foundational language skills in learners.
