The MAP® Growth™ theory of action describes key features of MAP Growth and its position in a comprehensive assessment system. The basic premise of the theory of action is that all students learn when MAP Growth is situated in a comprehensive assessment system and used for its intended purposes to yield information about student learning and enable educators to make data-informed decisions about curriculum and instruction. The infographic illustrates the components of the MAP Growth theory of action, shedding light on the connectedness of the parts and the claims that are central to the validity argument. Evidence for the claims is described in the MAP Growth technical report (NWEA®, 2019) and other research reports.
