It has the same meaning regardless of grade or age of the student. Paper presented at the annual meeting of the American Educational Research Association, Chicago.) For further information on NWEA research -ĩ RIT (Rasch unIT) Score Characteristics of the RIT Scale include: A long-term study of the stability of item parameter estimates. Alignment ensures that student abilities can be meaningfully NWEA have demonstrated measure-invariance beyond anything achieved anywhere else in the human sciences. All MAP test items have a single associated RIT value and items are aligned to state or Common Core content standards within the MAP tests.
Obtain the RIT value of test items by using a rigorous calibration process that ensures the integrity of the assessment. To ensure test reliability, validity, and fairness across all populations tested, the NWEA Research team regularly conducts a variety of studies and analyses such as: pool depth analysis, test validation, comparability studies, and Differential Item Functioning (DIF)- monitoring item quality to ensure that functioning remains constant across subgroups of students when ability is controlled. This Fall, MAP will test close to 8 million students (with >50% testing on Web-based MAP).Ĭreated the RIT scale because they required a consistent, precise tool that would provide accurate measurement of each student’s academic growth (Cross-grade, equal-interval vertical scale developed 30+ years ago according to Item Response Theory principles) development and use of NWEA assessments guided by the Standards for Educational and Psychological Testing that were developed jointly by the American Educational Research Association (AERA), American Psychological Association (APA), and the National Council on Measurement in Education (NCME).
