Lexile ranges describe text complexity and do not have a direct correlation to grade level. Which statement is true?

• A. They map directly to grade levels
• B. They do not have a direct correlation to grade level
• C. They measure running speed
• D. They measure vocabulary size

Answer: (B)

Lexile ranges describe how difficult a text is for a typical reader, not the grade level of the reader. The measure looks at sentence length and word difficulty (how often words occur in everyday written English) to estimate text complexity. Because grade level is a school benchmark tied to standards and curricula, there isn’t a direct, one-to-one mapping between a Lexile range and a student’s grade. A student in a certain grade might read texts at a higher or lower Lexile level than typical for that grade, depending on individual strengths and background knowledge. That’s why the true statement is that Lexile ranges do not have a direct correlation to grade level. Lexile doesn’t measure running speed or vocabulary size; it assesses text difficulty through structural features of the text rather than the reader’s overall vocabulary inventory or fluency.
