The Content Proximity Project was designed to improve the content validity of the MAP® Growth™ assessments while retaining the ability for the test to adapt off-grade and meet students wherever they are in their learning. Two main features of the project were the development of an enhanced item selection algorithm, and a spring pilot study conducted in volunteer school districts. The purpose of the pilot study was to evaluate the new algorithm during live testing, study the comparability of scores with traditional MAP Growth assessments, and produce evidence of test content validity and score reliability. The pilot study began in spring 2022 with a group of NWEA Partners who volunteered to participate. The Content Proximity Project was initiated with several benefits in mind. The primary benefits are enhanced content validity, improved perceptions of test quality, and greater test taking engagement. The test will continue to adapt off grade when needed to deliver items of suitable difficulty for a student. However, this adaptation will be done in such a way that test events will be more closely aligned with grade-level content, especially for students exhibiting typical performance for a grade. The stronger preference for grade-level content means that the test more closely matches the subject matter students have an opportunity to learn in school. Subsequently, MAP Growth scores should allow for better connections to curriculum materials and resources, and produce scores that are more highly correlated with end-of-year summative tests.
