Lexile ranges are used to gauge reading difficulty and support selecting texts. Which statement is accurate?

• A. They provide a direct grade-level equivalent
• B. They provide a means to approximate text complexity and support selection
• C. They measure reader IQ
• D. They measure reading speed

Answer: (B)

Lexile measures describe how difficult a text is and how well a reader is likely to understand it, using a common scale for both text and reader. By placing both the book and the reader on the same scale, you can estimate whether a given text matches the reader’s current abilities and choose texts that are within a productive challenge range. This helps teachers and students target materials that support growth without overwhelming or under-challenging the reader. It’s a practical tool for selecting texts and planning instruction.

This isn’t about mapping to exact grade levels, measuring intelligence, or judging reading speed.
