The Influence of Graduate Student Mentoring Experiences on Program Completion and Career Expectations

Graduate STEM education in the U.S. has experienced continued growth in enrollment, due to its strong international reputation. Yet, attrition rates among students remain high. Mentoring is frequently identified as a critical factor for supporting graduate student success; however, there is limited empirical evidence regarding the most effective mentoring practices for graduate STEM students. The Mentoring Experiences of Graduate Students Survey (MEGSS) was developed and validated with data from 280 graduate STEM students enrolled in a large, public, research-intensive university in the Eastern U.S. Exploratory factor analysis was performed to examine the survey’s reliability and construct validity. A five-factor, 38-item model was developed, consisting of the following subscales: psychosocial support, program completion, research and writing support, career expectations, and career support. The findings show statistically significant differences in students’ perceptions of mentoring experiences and anticipated outcomes based on gender, citizenship, and stage in the program. Recommendations are offered for faculty mentors and institutions to strengthen mentoring practices, particularly in psychosocial areas, research and writing, and career support. Extending the distribution of MEGSS to other graduate research programs (including non-STEM) could identify mentoring gaps and inform evidence-based strategies to strengthen graduate student development.
