Average Book Level Goal
There are three Reading Practice goals that you can set for your students: average percent correct, points, and average book level.
A student's average book level is the average level of the books on which the student passed Reading Practice Quizzes during the goal time period. Accelerated Reader calculates the average ATOS book level as a weighted average based on word count (to take into consideration not just difficulty of the text but also the amount of time spent reading).
When setting a goal for average ATOS book level, consider the student's reading level and Zone of Proximal Development (ZPD), which is a range of book levels that are neither too easy nor too challenging. We recommend setting the average book level as a minimum goal - at or near the lower end of the ZPD.
