The purpose of Accelerated Reader (AR) is to enable powerful practice which results in successful encounters with text.

A student's ZPD represents the level of difficulty that is neither too hard nor too easy. It is a customized book level range based on the results of a STAR assessment.

Book level indicates the difficulty of text, not the maturity of the content.

Interest level tells you which grade levels a book's themes and ideas are appropriate.

Points are assigned to a book based primarily on its length (i.e. word count).

The number of points a student earns tells you how much reading a student has done, in other words, time on task.

The most important factor is accelerated reading growth is comprehension. This is reflected in the "average percent correct" listed on all AR reports.
