Math and science homework is too easy for some fourth- and eighth-graders at public, private, and charter schools in the District, according to a Center for American Progress study.

Thirty-nine percent of D.C. fourth-graders said that their math homework was often or always too easy, compared to 37 percent nationally. Meanwhile, either D.C.’s eight-grade students are really smart or its math work is a piece of cake, because 34 percent of students said it was often or always too easy, compared to 29 percent of eighth-graders nationally.

Ulrich Boser and Lindsay Rosenthal, the study’s authors, write that the results show the need for more rigorous standards:

Many schools are not challenging students and large percentages of students report that their school work is “too easy.” If students are going to succeed in the competitive global economy, they need to be exposed to a rigorous curriculum. But many students believe their class work is too easy. Twenty-nine percent of eighth-grade math students nationwide, for instance, report that their math work is often or always too easy. In some states like Virginia, nearly a third of middle-school students reported their work was often or always too easy.
