Northwest Evaluation Association regularly conducts studies of alignment between the RIT scale and the scales used for statewide achievement tests. In recent years, educational experts have put increasing emphasis on the need for triangulation of student achievement information in order to assure that important educational decisions are based on data that is robust and corroborated. Indeed, many school systems use NWEA assessments as one way in which they triangulate data from their state assessment and other tests that may be in use in their district. The catalyst for this investigation was completion of a recent study to confirm and monitor the alignment between the PACT and NWEA assessments (Cronin, 2004). For the most part it was found that the two assessments remained closely correlated and that NWEA results predicted PACT status reasonably well. Nevertheless, it was also found that performance level estimates at a few grades showed large changes and that the predictive accuracy statistics stemming from the 2004 study were both lower than those generated from the 2002 study and also lower than those gathered from most of the other state studies.(Contains 12 tables.)
