This study, part of OECD/CERI's project on Measuring the Social Outcomes of Learning, investigates the relationship between educational attainment and political participation in Austria. First, a model based on various theoretical considerations is introduced. This incorporates direct educational effects as well as indirect effects that occur through material resources, social capital, civic orientations and values. Using a multivariate analytical approach the model is applied to the 2002 European Social Survey. Three forms of political participation are distinguished, namely voting, elite-directed and elite-challenging activities. Educational attainment is found to have significant effects on all three types but the strongest impact is on elite-challenging activities. The latter includes forms of political action such as signing petitions and buying or boycotting certain products which are increasingly accepted as a legitimate way to express one's political preferences. Most of the effects of education arise through intermediate variables, including social capital (especially affiliation with non-political organisations), civic orientations (political interest as well as internal and external efficacy) and individual (postmaterialist) values. The effect of education on elite-directed activity operated primarily through organisational affiliation, as well as internal and external efficacy. In contrast, the effect of education on elite-challenging activity seems to be fostered via social environments that combine high levels of political interest, interpersonal trust, postmaterialist values and a certain degree of scepticism against political institutions. The paper concludes with suggestions for policy and research.
