The discipline of political science examines pressing questions about governance, politics, and power. Our ability to generate accurate and actionable findings is enhanced by including in disciplinary discussions, institutions, and publications the voices of a diverse community of scholars. The PS-PSI aims to diversify and strengthen the pool of students recruited and admitted to graduate programs, and the group of scholars retained as faculty in political science. Our Institute has two overarching practical objectives: (1) to demystify the process of applying to graduate programs and obtaining a doctorate and to help students from underrepresented populations prepare to do so; and (2) to equip students to make an informed choice about pursuing a graduate degree, begin to see a place for themselves and their work in graduate school and beyond, and understand the multiple career paths that political science PhDs can pursue.
