Lexile® Tracking Document Explained

The Lexile Framework

The Lexile Framework for Reading is a scientific approach that places both the reader and text on the same developmental scale. The Lexile Analyzer® uses an algorithm to evaluate the text complexity of books, articles, and other materials.

The Lexile Analyzer measures the complexity of the text by breaking down the entire piece and studying its characteristics, such as sentence length and word frequency, which represent the syntactic and semantic challenges that the text presents to a reader. The outcome is the text complexity, expressed as a Lexile measure, along with information on the word count, mean sentence length and mean log frequency. Generally, longer sentences and words of lower frequency lead to higher Lexile measures; shorter sentences and words of higher frequency lead to lower Lexile measures. Texts such as lists, poetry and song lyrics are not analysed because they lack conventional punctuation.

Pupils and parents should look for reading materials with a reading comprehension “sweet spot” of 100L below to 50L above their Lexile measure. Reading materials in this range will provide an ideal level of challenge while maintaining comprehension.

 

Lexile Key

The Lexile Key is a colour coded tool to show each pupil’s reading start level and current level using the Lexile® measure.

Click here for a guide to the Lexile Ranges associated with each level on Reading Plus. A Lexile measure is defined as a text’s readability level. The lower the range, the easier a text is to read.

Elements of the Lexile Tracking Document Explained

 

Benchmark date & time (start date)

When pupils started the program. Use this to measure how many lessons should have been completed against our recommended target of 5 Reading lessons per week.

Total Usage to date (hours)

Usage and progress are strongly linked. You may see in your tracking documents that the pupils that have spent more time on the program have the greater gains. View column Level Gain.

Total Reading Lessons (SR)

The minimum recommended number of reading lessons is 5 per week with each lesson taking on average 10-15 minutes, ideally in slots of 3 x 30-minute sessions.
