This document provides detailed information on how to interpret and use the results provided by the Kentucky Core Content Test (KCCT), Writing Portfolio, Norm-referenced Test, and other components of the Commonwealth Accountability Testing System (CATS) administered during the 2001-2002 school year. As required by statute, these reports are received by school districts on or before September 15 each year. Individual pages of the Kentucky Performance Report and three separate student level reports are explained in detail. This interpretive guide contains detailed information about the four performance levels that are the heart and soul of the CATS: Novice, Apprentice, Proficient, and Distinguished. How these performance levels were developed is explained. The accommodations and modifications made to individual tests in the assessment system are described, and each of the tests is also described. Scoring and scaling are also reviewed for each of the tests that make up the CATS. One appendix outlines the cut points for the performance levels, and the second appendix contains a glossary for the CATS. The third appendix is a series of questions commonly asked about the CATS, with answers. (SLD)
