Many students who attend school in California also take paper or computerized-adaptive tests developed in cooperation with the Northwest Evaluation Association (NWEA). These tests report student performance on a single, cross-grade scale, which NWEA calls the RIT scale. This scale was developed using Rasch scaling methodologies. RIT-based tests…

The current study investigates the effect of adding an individual growth measure to the primary definition of AYP. A variety of approaches to measuring growth have already been identified and are in use in schools across the country.
