The Reading Observation Scale (ROS) is 25-item, norm-referenced teachers’ rating scale that can be used to assess students’ daily classroom reading behaviours. The ROS is normed on a sample of 1,338 persons in 15 U.S. states and has proven reliability and validity (including evidence of sensitivity and specificity). Its items relate to specific reading behaviours readily seen in instructional settings (e.g., “enjoys reading,” “retells read material correctly”). Teachers or other knowledgeable professionals rate the items on a 5-point scale. Usually, only 5 to 10 minutes are required to rate a student’s observed reading behaviours. The scores from the ROS can be used to (a) support a referral, (b) expand the scope of a comprehensive reading evaluation, (c) compare teachers’ ratings with test results, (d) help plan interventions, and (e) monitor the effectiveness of interventions. Results are particularly useful when used as part of a comprehensive reading evaluation or as a pre-referral/referral tool.
