This study examines the association between high school journalism and civic engagement in early adulthood, independent of other civic activities. Nationally representative data show that taking high school journalism classes is related positively to voting in the years following high school, to a similar degree that taking debate classes or participating in student government is related to voting. High school journalism also moderates the association between family socioeconomics and civic engagement. Underprivileged student journalists tend to vote and volunteer more than their non-journalism peers. The study theorizes journalism education’s unique contributions to civic development and civic communication competence.
