In most graduate student programs, mentoring relationships are a critical component that influences a student’s experience and accomplishments as a developing researcher. These relationships include relationships with research advisors, committee members, and others who support students’ professional development. Information on the quality of these mentor-mentee relationships has typically been gathered informally through conversations with graduate students and faculty, but has not been systematically measured to make improvements and inform decision-making. Such lack of structure raises the potential for unequal treatment and even detrimental experiences that disadvantage students, especially those from historically excluded or marginalized groups. To address this gap in assessment of graduate student training, we have developed and pilot tested a graduate mentorship assessment tool and process for generating informative and actionable reports that mentors and mentees can use to improve their interactions and maintain a high-quality relationship over time. A manuscript describing the tool, process, and pilot test results is currently under review.
