This paper profiles Louisiana's test score trends through 2008-09. Between 2005 and 2009, trends on state tests and NAEP (National Assessment of Educational Progress) sometimes differed. On the state test, the percentages of students reaching the proficient level increased at grades 4 and 8 in both reading and math. On NAEP, the percentage of students reaching the basic level increased in grade 8 math, showed no change in grade 8 reading, and decreased in grade 4 reading and math. Average annual changes in percentages proficient/basic were larger in a positive direction on the state test than on NAEP in both subjects and both grades. Average (mean) scores increased on both the state and NAEP tests in grade 8 reading and math. At grade 4, however, average scores in both subjects went up on the state test but down on NAEP.
