Direct Behavior Ratings (DBRs) are behavioral assessment methods that combine the benefits of systematic direct observation and behavior rating scales. That is, DBRs involve the observation of operationally defined target behaviors during a prespecified observation period and the evaluation of those behaviors via brief ratings. In this way, DBR is considered a hybrid assessment method. This article describes the landscape of DBR tools and provides an overview of the procedures and research currently available to support the use of one specific version, DBR-Single Item Scales (DBR-SIS), for progress monitoring within multi-tiered systems of support.
