After decades of neglect, civic education is back on the agenda of politica
l science in the United States. Despite huge increases in the formal educat
ional attainment of the US population during the past 50 years, levels of p
olitical knowledge have barely budged. Today's college graduates know no mo
re about politics than did high school graduates in 1950. Recent research i
ndicates that levels of political knowledge affect the acceptance of democr
atic principles, attitudes toward specific issues, and political participat
ion. There is evidence that political participation is in part a positional
good and is shaped by relative as well as absolute levels of educational a
ttainment. Contrary to findings from 30 years ago, recent research suggests
that traditional classroom-based civic education can significantly raise p
olitical knowledge. Service learning-a combination of community-based civic
experience and systematic classroom reflection on that experience-is a pro
mising innovation, but program evaluations have yielded mixed results. Long
standing fears that private schools will not shape democratic citizens are
not supported by the evidence.
