To analyze the representation of the mathematical practices in the three assessments, the researcher used a method similar to that identified in the WAT to determine which practices each assessment item included. Thus, the mathematical practices were analyzed utilizing both qualitative and quantitative data and also included a meeting with content experts to discuss results of the data gathered.Findings of the study indicated that the JCPS interim assessments were considered well aligned to the 8 th -grade CCSSM content standards. However, the ACT EXPLORE and 2009 NAEP released items did not align with the 8 th -grade CCSSM.Further analyses of the two national exams revealed a higher level of alignment with the 7 th -grade CCSSM content but warrant further analysis. Due to a lack of methodological support for identifying the mathematical practices, no results were reported regarding the level of representation of the practices in each of the assessments.
