This community-based research investigated the relationship among Holocaust knowledge, Holocaust education experiences, and citizenship values in adults residing in the US. This study contributes to the literature an inferential investigation that reports positive civic attitudes associated with Holocaust education. A moderate correlation was identified, with approximately 10% of the variance in citizenship scores explained by Holocaust knowledge. Multiple regression analyses revealed Holocaust knowledge as the strongest predictor of citizenship values, followed by gender, suburban/urban childhood community, and learning about the Holocaust in school, respectively. Of eight unique Holocaust education experiences examined, learning about the Holocaust in school was the strongest predictor of citizenship values, followed by hearing a Holocaust survivor testimony in person or via electronic media, and visiting a Holocaust museum, respectively. Findings can inform Holocaust education policy, research, and practice, including the potential role of Holocaust curriculum in the larger context of moral and civic education.
