Recently NWEA completed a project to connect the scale of the Maryland School Assessment (MSA) with NWEA's RIT scale. One large school system participated in the study, using test information from a group of over 24,000 students enrolled in third, fourth and fifth grade who took both the MSA and NWEA reading tests in the spring of 2005. Information from these tests were used in a comprehensive study to identify the capacity of the RIT scale to predict success on the MSA 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. The authors estimated cut scores for each of the performance levels at grades three, four and five for reading. (Contains 2 figures and 4 tables.)
