Results from the 2013 NAEP assessments show fourth-and eighth-graders making progress in mathematics and reading. Nationally representative samples of more than 376,000 fourth-graders and 341,000 eighth-graders were assessed in either mathematics or reading in 2013. Results are reported for public and private school students in the nation, and for public school students in all 50 states, the District of Columbia, and Department of Defense schools. This snapshot report covers the overall results, achievement level percentages and average score results, comparison of the average scores in 2013 to other states/jurisdictions, average scores for state/jurisdiction and nation (public), results for student groups in 2013, and score gaps for student groups. In 2013, the average score of eighth-grade students in South Dakota was 287. This was higher than the average score of 284 for public school students in the nation. The average score for students in South Dakota in 2013 (287) was lower than their average score in 2011 (291) and was higher than their average score in 2003 (285). The score gap between higher performing students in South Dakota (those at the 75th percentile) and lower performing students (those at the 25th percentile) was 44 points in 2013. This performance gap was not significantly different from that in 2003 (41 points). The percentage of students in South Dakota who performed at or above the NAEP "Proficient" level was 38 percent in 2013.
