Estimated Lexile Score vs Average Sentence Length (words)
Formula
## How to Estimate a Lexile Score Lexile measures are based on sentence length (syntactic complexity) and word frequency (semantic difficulty). ### Simplified Formula **Lexile ≈ 200 x (ASL / 10) - 100 x MLWF + 800** Where ASL = Average Sentence Length and MLWF = Mean Log Word Frequency. Higher Lexile scores indicate more difficult text. Typical range: 200L (early reader) to 1600L (advanced).
Exemplo Resolvido
A text has average sentence length 15 and mean log word frequency 3.5.
- 01Lexile = round(200 x 15/10 - 100 x 3.5 + 800)
- 02= round(300 - 350 + 800) = round(750) = 750L
- 03Approximate grade level = round(750 / 100) = 8
Perguntas Frequentes
What is a good Lexile score for my child?
It depends on age. Grade 3: 520–820L, Grade 6: 925–1070L, Grade 9: 1050–1260L. Match books to your child's measured Lexile.
How is Lexile different from grade level?
Lexile is more precise and text-specific. Grade level is a general estimate, while Lexile allows matching a reader to specific books.
Can adults have Lexile scores?
Yes, adult readers typically range from 1000L to 1400L. Professional and academic texts can exceed 1400L.
