South Dakota students' scores in reading and math remained about the same in an annual test given to students across the state.
About 62,000 students in grades 3-8 and 11 were tested last spring.
The state Education Department reports that 75.5 percent of the students scored either proficient or advanced in reading, up slightly from last year.
About 76.7 percent of the students scored proficient or advanced in math, again up just slightly from a year earlier.
The tests have been used to measure annual progress under the federal education improvement law known as No Child Left Behind.
But South Dakota is moving to a new accountability system for schools that will look not only at tests scores, but also at academic growth and the effectiveness of teachers and principals.
