This paper profiles Washington's test score trends through 2008-09. Between 2005 and 2009, the percentages of students reaching the proficient level on the state test and the basic level on NAEP (National Assessment of Educational Progress) decreased in grade 4 reading. In grade 4 math, the percentage scoring proficient on the state test decreased while the percentage scoring basic on NAEP showed no change. Average annual declines were larger on the state test than on NAEP in grade 4 reading and math. Trends in average (mean) test scores on the state test and NAEP moved in the same downward direction in grade 4 reading as trends in percentages proficient/basic. In grade 4 math, average scores decreased on the state test and increased on NAEP. (Contains 1 footnote.)
