Grading Standards in Education Departments at Universities

Cory Koedel, University of Missouri, via a kind reader's email:

Students who take classes in education departments at universities receive significantly higher grades than students who take classes in other academic departments. The higher grades awarded by education departments cannot be explained by differences in student quality or by structural differences across departments (i.e., differences in class sizes). The remaining explanation is that the higher grades are the result of lower grading standards. This paper formally documents the grading-standards problem in education departments using administrative grade data from the 2007-2008 academic year. Because a large fraction of the teachers in K-12 schools receive training in education departments, I briefly discuss several possible consequences of the low grading standards for teacher quality in K-12 schools.

There is a large and growing research literature showing that teacher quality is an important determinant of student success (recent studies include Aaronson et al., 2007; Koedel, 2008; Nye et al., 2004; Rivkin et al., 2005; Rockoff, 2004).

But while there is persistent research into a variety of interventions aimed at improving teacher quality, surprisingly little attention has been paid to the primary training ground for K-12 teachers--education departments at universities.

This paper provides an evaluation of the grading standards in these education departments. I show that education students receive higher grades than do students in every other academic discipline. The grading discrepancies that I document cannot be explained by differences between education and non-education departments in student quality, or by structural differences across departments.

The likely explanation is grade inflation.

The earliest evidence on the grading-standards problem in education departments comes from Weiss and Rasmussen in 1960. They showed that undergraduate students taking classes in education departments were twice as likely to receive an "A" when compared to students taking classes in business or liberal arts departments. The low grading standards in education departments, illustrated by these authors over 50 years ago, are still prevalent today.
