Book level measures the readability of the text of a book or other reading material. Accelerated Reader Bookguide allows you to see either the ATOS book levels or Lexile® Measures for your books (see the General Preferences).
Points are a measure of the amount of reading practice a student is getting. Every Reading Practice Quiz has a point value assigned to it based on the book level and the word count of the book (the book's difficulty and length). If you add Teacher-Made Quizzes to Accelerated Reader, the program calculates the possible points based on the book level and word count that you enter for the quiz.
Students earn points by passing Reading Practice Quizzes, including the Teacher-Made Quizzes. The points that a student earns on a quiz are based on the total point value of the quiz and the mark the student received on it. Points are also one of the criteria used by Accelerated Reader to determine when students have achieved the certification levels.
