Calibration Study of POWER Performance Levels to the CASAS Scale. Research Brief No. 5
Posey, Virginia
CASAS - Comprehensive Adult Student Assessment Systems (NJ1)
The Adult Education and Family Literacy Act, as part of the Workforce Investment Act of 1998, requires programs to use standardized assessments to report learning gains for students in adult education programs. In addition, local and state agencies need an accountability tool for students who are difficult to assess adequately with a paper-and-pencil format. In this study CASAS sought to determine the feasibility of calibrating basic skills on the Providing Options for the Workplace, Education, and Rehabilitation (POWER) performance assessment and to establish corresponding difficulty estimates on the CASAS scale. The goal of the calibration was to achieve consistency of the POWER scoring system with guidelines of the National Reporting System (NRS) for adult education. Results indicate that performance levels (0-4) for each of the basic skills in a POWER assessment can be scaled and located on the CASAS scale score continuum. Therefore, agencies can use the POWER performance assessment to measure learning gains for students with developmental disabilities and for NRS reporting purposes.
