Reading Measures

ATOS Level

 Renaissance Learning^TM  has developed a computer based assessment capability that is used by over 73,000 schools. We reference the Accelerated Reader^TM (AR) score, called the ATOS Level, as part of our reviews. This gives parents an idea of the reading level of the book. If your child’s school does not use the AR system chances are it will soon.
