What does "Tier 2" vocabulary refer to in vocabulary instruction?

Tier 2 vocabulary refers to high-frequency words that are more sophisticated and used across various contexts. These words are essential for reading comprehension and more complex language use in both spoken and written forms. They appear frequently in texts and conversations and facilitate a deeper understanding of the material, allowing students to express ideas more clearly and accurately.

For example, words like "analyze," "concept," and "contribute" are categorized as Tier 2 because they are applicable in multiple subjects and situations, helping students to articulate thoughts and engage with different texts. By focusing on Tier 2 vocabulary, educators enable students to enhance their academic language skills, which are critical for success in learning across different disciplines.
