The present study with 248 German teachers examined the conceptual separability of six dimensions of teachers’ self-concept (pedagogical skills, subject content knowledge, consulting, innovation, media use, diagnostics) and three emotions (enjoyment, anger, anxiety) as well as relations of these constructs. Results showed that all self-concepts and emotions were clearly separable from each other. All six self-concepts were positively related to enjoyment and negatively related to anxiety and anger. However, regression analysis revealed that only self-concept of pedagogical skills was positively linked to enjoyment and negatively linked to anger, while only self-concept of subject content knowledge was negatively linked to anxiety.
