True experimental design and quasi-experimental design are considered to be rigorous research designs appropriate for assessing the impact of pedagogical interventions. This study explores the extent and application of experimental design in impact research on entrepreneurship education (EE) based on a systematic literature review. The findings reveal a substantial lack of methodologically rigorous studies on EE impact, which has severe implications for the accumulated knowledge on the subject. Furthermore, the article summarizes the findings from the body of experimental impact studies with a strong research design and concludes by indicating fruitful avenues for future research.
