The effects of mixed-age classes in Sweden
() and Erica Lindahl
Abstract: Mixed-aged classes (MA-classes) are a common phenomenon
around the world. In Sweden, these types of classes increased rapidly
during the 1980:s and 1990:s. But the scientific evidence of the benefits
of MA-classes is not convincing. In this paper, we estimate the effect of
attending an MA-class during grades 4–6 on students’ cognitive skills.
Using a unique survey with information on students, parents and teachers,
we are able to control for many factors that could otherwise bias the
results. We find a negative effect on the short-run cognitive skills, as
measured by grade 6 cognitive tests.
