Bob from Brookeville, MD asked:
- Based on the percentage of 12th graders that scored in the proficient range in Economics in 2006, compared to say Math or Reading results from 2005, is it accurate to say that 12th graders know more Economics than Math?
Dr. Peggy G. Carr 's response:
- Bob, we actually establish separate scales for each subject area that we assess. In addition, when the National Assessment Governing Board set its achievement levels (Basic, Proficient, and Advanced), they also set them separately for each subject area. Therefore, it is not really possible to directly compare mathematics or reading results to the results we released today in economics. That being said, it is true that all of the Governing Board's achievement levels are initially informed by the generic policy descriptions the Board has established for each of the three levels. (For example, Basic denotes partial mastery of the knowledge and skills that are fundamental for Proficient work at a given grade.) So--it is possible to make some very general comparisons across subjects--but, please keep in mind the problems in making direct comparisons I described above.
