Recently the Northwest Evaluation Association (NWEA) completed a project to connect the scale of the MCA and BST with NWEA's RIT scale. Six Minnesota systems participated in the study, using test information from a group of over 13,000 students enrolled in third, fifth, and eighth grades who took these Minnesota Assessments and NWEA tests in the spring 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 Minnesota Assessments and to identify performance level scores on the RIT scale that would indicate a good chance of success on this test. After the announcement of the study results, the Minnesota Department of Education informed schools that the MCA scales and proficiency cut points needed to be changed. Based on their announced changes, NWEA have made adjustments in their estimated RIT cut scores for the MCA tests that are presented in this document. (Contains 18 tables and 3 figures.)
