This paper profiles North Dakota's test score trends through 2008-09. Between 2005 and 2009, the percentage of students reaching the proficient level on the state test and the basic level on NAEP (National Assessment of Educational Progress) increased in grades 4 and 8 in both reading and math. Average annual gains were larger on the state test than NAEP in grade 4 reading and grade 8 reading and math. In grade 4 math, however, average annual gains were greater on NAEP than on the state test. Trends in average (mean) scores generally moved in the same direction as trends in percentages proficient/basic. Average scores increased on both assessments except for a decrease in NAEP scores in grade 8 reading. (Contains 1 footnote.)
