As a possible indicator of test score manipulations, comparisons are made between state test score trends and NAEP trends in reading and mathematics in grades 4 and 8. Due to technical limitations in comparing simple changes in proficiency rates, a scale-invariant framework based on P-P plots is used to estimate state-NAEP score trend discrepancy effect sizes. These effect sizes show that state trends were significantly larger than NAEP trends from 2003-05, 2005-07, and 2003-07.As a possible indicator of test score manipulations, comparisons are made between state test score trends and NAEP trends in reading and mathematics in grades 4 and 8.
