Recently NWEA completed a project to connect the scale of the WKCE with NWEA's RIT scale. Six Wisconsin school systems participated in the study, using test information from a group of over 1,500 students enrolled in fourth, eighth, and tenth grade who took both the WKCE and NWEA tests in the fall of 2003. Information from these tests was used in a comprehensive study to identify the capacity of the RIT scale to predict success on the WKCE and to identify performance level scores on the RIT scale that would indicate a good chance of success on this test. Three methodologies, linear regression, second order regression, and Rasch status on standards (called Rasch SOS) were used to derive estimates of cut scores. In each case the most accurate of the three estimates was used to arrive at the recommended cut score seen in this report. Cut scores for each of the performance levels at grades four and eight were estimated. Because of the small number of participating students at grade 10 (n=122), they estimated only the cut score for "proficient" performance at that grade. (Contains 6 tables and 3 figures.)
