To achieve this project, we developed a method to impute missing data necessary for calculating subset norms. Complete data sets are evaluated for the number of items that can be removed such norm stability is maintained. Item removal studies include easiest items, hardest items, random items, and items by content area. This work is creating new opportunities for course and programmatic assessment by content area rather than singly based on complete examination scores.<\/p>\n<p><u>References<\/u><\/p>\n<ul>\n<li>Brandriet, A., &amp; Holme, T.
