Abstract	This study investigated the relationship between the scales used for the ISTEP+ assessments and the RIT scales used to report performance on Northwest Evaluation Association tests. The RIT scale was developed using Rasch scaling methodologies. RIT-based tests are used to inform a variety of educational decisions at the district, school, and classroom level. They are also used to monitor the academic growth of students and cohorts. Districts choose whether to include these assessments in their local assessment programs. The study estimated the changes in reading and mathematics RIT score equivalents for the ISTEP+ performance levels in those subjects. Test records for more than 20,000 students were included in this study. Three methods generated an estimate of RIT cut scores that could be used to project ISTEP+ performance levels. Rasch SOS methods generally produced the most accurate cut score estimates. Accuracy of predicting ISTEP+ passing performance was well above 80% for all grades and subjects studied when using the best methodology. The study included test records from over 25,500 students enrolled in 11 Indiana school systems. These students had taken both the state assessment and NWEA assessments in fall of 2004; many had also taken NWEA assessments in spring of 2004. Student records were included when a student had both a valid NWEA scale score and a valid ISTEP+ score in the equivalent subject for the fall season. The primary questions addressed in the study are: (1) What RIT scores correspond to various performance levels on the ISTEP+ tests? (2) How do these RIT scores differ from the 2003 estimates of performance level?;and (3) How well can performance on the Indiana assessments be predicted from RIT scores when NWEA assessments are administered in the same fall and the prior spring?
