In the Education Next study, the researchers looked at the percentage of fourth- and eighth-grade students in each state that performed proficient on the 2009 NAEP math and reading exams, and then compared that with the percentage of students deemed proficient on state assessments.
States with a similar percentage of students proficient on state tests and on the NAEP test earned an ‘A.’ But lower grades were given to states with high percentages of students proficient on state exams but with low percentages of proficient students on NAEP. The exact grade depended on how much lower state results were than the world-class NAEP.
Tennessee, with an 'F,' was at the bottom of the list of states and the District of Columbia. It reported that 90 percent of its fourth-grade students were proficient in math on Tennessee’s own assessment, though NAEP tests showed that only 28 percent were performing at the proficient level. Results in reading at the fourth- and eighth-grade reading levels were similar.
Delaware earned a ‘C minus.’ The state said that 77 percent of its fourth-grade students were proficient in math though on the NAEP only 36 percent were. In eighth-grade reading, Delaware said 81 percent of its students were proficient, though only 31 percent were proficient on NAEP.
