Can you please explain how The Sun Also Rises by Ernest Hemingway can have a Lexile Level of 610 and a Lexile level of 1420 at the same time? That is a HUGE variance.
Also, based on your search function a Lego Harry Potter Sticker book is 720 whereas JD Salinger's Catcher in the Rye is 790. Is there something askew with your database?
Thank you for your interest in the Lexile® Framework for Reading!
The 610L is the Lexile® measure of the actual novel and the 1420L is the measure of a collection of critical essays (basically reviews). Anytime you see a large discrepancy such as this it may be useful to search each ISBN on Amazon for a detailed description of each book.
As far as Lego Harry Potter and Catcher in the Rye… In order to obtain a Lexile® measure for a book or article, text is split into 125-word slices. Each slice is compared to the nearly 600-million word Lexile® corpus – taken from a variety of sources and genres – and words in each sentence are counted. The sentence length and difficulty of the vocabulary is examined throughout the book. These calculations are put into the Lexile® equation. Then, each slice’s resulting Lexile® measure is applied to the Rasch psychometric model to determine the Lexile® measure for the entire text.
Lexile® measures do NOT measure age-appropriateness, the book quality, the book’s theme/content or other such characteristics of the book as it only analyzes the semantic and syntactic characteristics. For example, The Grapes of Wrath is a fairly simple book to read but may have a theme that is inappropriate for a certain age group. The Diary of a Wimpy Kid may have more complex words and phrases and therefore has a higher Lexile® measure.
Thanks again and please let us know if you have any further questions.
