Accelerated Reader BookGuide

AR BookGuide is a collection management tool that automates alignment of your books with Accelerated Reader quizzes.

ATOS Analyser

ATOS and Lexile measures are both valid and reliable measures of text complexity that provide a basis for matching students to reading materials. As with all readability formulas, the resulting value is an estimate of the understandability of the text. Accelerated Reader, myON Reader, Star Reading, and AR BookFinder display book level data in either ATOS or Lexile measures, based on the preference of your school or district.
