Over the last decades, many European Union countries have invested in strengthening participatory learning in citizenship education policy and practice. This survey study provides insight into how high school teachers in the Netherlands advance critical democratic citizenship and a democratic school culture in the context of mock elections. A quarter of the schools that organized mock elections in 2017 participated in the study. Analysis reveals that attention for critical, value-related teacher aims and teacher aims directed at strengthening a democratic school culture is still limited in mock election-related education. It also shows that half of the participating schools offer less than one hour of mock election-related educational activities, and that one-third of the teachers would like to offer additional educational activities.
