This paper examines professor teaching and research ratings. Specifically, this research examines the extent to which professors excel both at teaching and research. Similarly, this work examines the extent that professors who excel in one area are deficient in the other. Data for analysis involves paired research and teaching data for 300 business professors from 104 U.S. universities. The results show that only a small number of professors excel both at teaching and research. Many professors are seriously deficient on one or both dimensions. The data reveals mixed evidence on gender differences. Results show that faculty at private universities outperform faculty at public universities.
