If enabled by your library or school, this database collection uses the Lexile Framework® for Reading score.
The Lexile® score rates the difficulty of text based on word frequency and sentence length. A score is displayed as a number followed by an L, such as 850L.
The Lexile® reading level (or scale) is a developmental and educational tool designed to match a reader's skills to the text. The reading level assigns a category to a range of scores. For example, scores below 200L are considered beginning-reader material, while scores above 1700L are considered advanced (i.e., at the college level).
