- To assess the reading difficulty to texts
- To assess students' ranges of reading comprehension

Students' Lexile levels are measured using the Scholastic Reading Inventory or SRI
The SRI is an interactive test that determines students' comprehension ranges in Lexiles
Students are assessed three times a year - September, January and May
