## How to choose a 900L–999L book for your child

Five steps to match a Lexile-banded book to a reader's actual ability and interests:

1. **Confirm the reader's measured Lexile.** Pull the latest Lexile score from school assessments (STAR, MAP, iReady, NWEA). A reader 100-200L below 900L will find these books challenging; 100L above 999L will find them easy.
2. **Pick a book at +0 to +200L above their measured level.** Research from MetaMetrics shows readers grow most when reading 0-200L above their measured ability.
3. **Cross-check with the book's grade-band citation.** Each book's detail page lists every grade where US schools assign it.
4. **Confirm thematic appropriateness.** Lexile measures prose complexity, not content. Check the Themes + Content notes section on each book's detail page.
5. **Verify with the curriculum citation.** A book widely cited across multiple frameworks signals broader teacher consensus on age-appropriateness.
