Mathematics Framework for the 2013 NAEP
To provide clarity and specificity in the objectives for each grade level, the framework matrix (Exhibits 3, 4, 5, 6, and 7) depicts the particular objectives appropriate for assessment under each subtopic. For example, within the Number Properties and Operations subtopic of Number Sense, specific objectives are listed for assessment at grades 4, 8, and 12. The same objective at different grade levels depicts a developmental sequence for that concept or skill. An empty cell in the matrix conveys that a particular objective is not appropriate for assessment at that grade level.
