Test series by NRS levels and Scale Score Ranges

These charts provide a visual representation of the test forms in the five series and how they relate to student skill levels in terms of the CASAS and NRS scales. In this way they show the comparative level of difficulty of the tests and how they overlap in providing an array of test instruments for assessing learning progress. The charts include appraisals and pre- and post-tests in reading, math, and listening.
Many people find this chart to be a great "birds-eye-view" to quickly understand CASAS forms numbers and how they relate to the CASAS levels and scale.
