This study investigates a questionnaire that measures epistemological beliefs in history. Participants were 922 exam students. A basic division between naïve and nuanced ideas underpins the questionnaire. However, results show this division oversimplifies the underlying structure. Exploratory factor analysis extracted 5 factors, separating items connected to nature of knowledge from nature of knowing. Furthermore, EFA problematized the distinction between naïve and nuanced ideas on subjectivity. Experts also reported large variance on subjectivity; therefore, these items were excluded from the questionnaire. The final questionnaire contained 3 factors focusing on the objective nature of (1) historical knowledge and (2) historical knowing, and on (3) methodological criteria. Finally, differences between school tracks and relationships between epistemological beliefs, interest and history grade were explored.
