Internationally, the attention to pre-service teacher research and inquiry in teacher education is growing. In the Netherlands, pre-service teacher research has been a compulsory component of primary teacher education for a decade. The assumption is that such research can help 'future-proof' teachers. This study examines the relationships among the quality of inquiry, the quality of teaching and pre-service teachers' perception of this research. Scores for assessments of graduating pre-service teachers (N=650) and a survey (n=236) were used as measurements. The findings indicate positive perceptions of practitioner research and a positive correlation between the quality of inquiry and quality of teaching. Using these data, the study identifies four profiles of pre-service teachers, differentiated by their perceived learning outcomes.
