Common Core added an important piece to the mounting evidence that
curriculum continues to narrow at the expense of vital academic subjects
with yesterday’s release
of survey data from 1,001 third through 12th-grade teachers. Fully
two-thirds of those surveyed agreed that extra attention to math and
language arts is crowding out other subjects, with the sentiment
particularly strong among elementary-school teachers. Of those who saw
the curriculum narrowing, 93 percent pointed to state tests as the
primary culprits.

Focusing on math and reading at the expense of subjects like science
and social studies requires serious scrutiny, and Common Core should be
applauded for bringing more attention to the issue. Critics of
test-based accountability will be quick to cite the survey as evidence
of the deleterious effects of testing, but the numbers tell a more
complicated story. 90 percent of teachers said that inclusion in state
testing results in a subject being taken more seriously. Of those who
reported crowding out, 60 percent said that the increased focus on math
and language arts boosted test scores and 46 percent agreed that it
resulted in improved skills and knowledge. Is the problem testing
itself, or that test-based accountability is so narrowly focused in most
