Lesley offers three Ph.D. in Educational Studies specializations for educators seeking to attain leadership credentials or deepen their expertise. We define Educational Studies as an interdisciplinary area of inquiry that examines the individual and social processes of learning and teaching in institutional and social contexts. The study of cognition, learning, and human development is integrated with the study of institutions, organizations, and cultures. The Educational Leadership specialization include a summer residency. The Adult Learning specialization includes a summer and a winter residency.
