The Graduate and Professional Skills (GradProSkills) program is an initiative developed and run by Concordia University's School of Graduate Studies and the university's Office of the Vice-President, Research and Graduate Studies. This paper presents a case study in which we describe the development, implementation, and evaluative components of the GradProSkills program. Drawing on data from a rigorously validated workshop evaluation tool and from attendance figures spanning a period of a little over two and a half years, we provide a picture of how Concordia's graduate students are benefiting from the GradProSkills program. We present the results of both descriptive and inferential statistical analyses run on a pilot group of registrants who provided evaluation data (n = 3,292). Our case study contributes an empirically derived model of extracurricular programming, with contextualizing details of administrative structures, curriculum-development initiatives, and partnership efforts that have been used in operating the GradProSkills program.
