MDES has two main design features. First, the study collects data from five entire cohorts of new Ph.D. students (i.e., the study is a census). A census study allows Rackham researchers to measure the characteristics of sub-groups more accurately than a sample study would. By collecting data from five new cohorts, it also allows Rackham to examine how incoming students’ expectations of graduate study, academic preparation, and motivation to earn a Ph.D. change over time. Second, the study collects data on an annual basis from the same students beginning in their first year of study (i.e., the study is longitudinal). This feature allows Rackham to measure growth and change within students over time, thereby providing insight into graduate students’ socialization experiences and emerging scholarly identities during the duration of doctoral study.

The two design features of MDES are illustrated in the figure above. In 2017 through 2021, all incoming Rackham Ph.D. students will be administered Wave 1 of MDES. Wave 1 collects baseline data and information about students’ preparation for doctoral study. Characteristics of cohorts can be compared by examining Wave 1 data over multiple years.
The longitudinal nature of the study is best illustrated by following the progress of the 2017 cohort. This cohort will take Wave 2 of the MDES during their second year of study, in 2018, Wave 3 during their third year of study, in 2019, and so on. Wave 2 through Wave 5 will collect data on students’ experiences in their programs. By 2021, Rackham will possess some of the nation’s richest and most comprehensive data on Ph.D. students. This will allow Rackham to disseminate findings and suggestions to the graduate education community about how doctoral training can be strengthened, leading to more equitable graduate completion rates and career outcomes in the United States.
MDES is guided by a comprehensive conceptual framework developed by the Rackham Institutional Research staff. Drawing from professional socialization theory, the MDES framework holds that the central task of doctoral study is the development of a disciplinary identity. We define disciplinary identity as the professional identity of someone who works to advance scholarship, research, and practice within an academic discipline. Those who have high levels of disciplinary identity are committed to their field of study, feel included in a community of practice within that field of study, and have integrated their identity as a member of the discipline into their overall self-concept.
Theory suggests that individuals are socialized into holding disciplinary identities and that the people and environments that students encounter while working on their Ph.D.s play a critical role in this socialization. Interactions with the student’s advisor(s) or mentor(s), peers, and departmental faculty produce academic and social experiences.
The framework also proposes that students’ ability or willingness to engage in the socialization process depends upon how well their motivation is supported. According to self-determination theory (Deci & Ryan), individuals have three psychological needs that must be satisfied in order to support their motivation and well-being: autonomy, competence, and relatedness.
We hypothesize that students’ progression through doctoral programs is an iterative process by which they gradually shift their identity from being a student/knowledge consumer in their discipline to being a scholar/knowledge producer in their discipline.
