Yes. From the article: More ominous were the results for 13-year-olds, who experienced statistically significant drops of three and five points in reading and math, respectively.

Black students dropped eight points and Hispanic students four points; both decreases widened their score gap with white students, whose scores were statistically unchanged from 2012.
