This paper profiles New Mexico'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) increased in grade 4 math and grade 8 reading and math. In grade 4 reading, the percentage basic on NAEP increased slightly between 2005 and 2009, while the percentage proficient on the state test showed no change. Average annual gains were larger on the state test than on NAEP in grade 8 reading and math. In grade 4 reading and math, average annual gains were larger on NAEP than on the state test. Trends in average (mean) scores generally moved in the same direction as trends in percentages proficient/basic. (Contains 1 footnote.)
