Student Development Theory (SDT) is a specialized skill that involves understanding and applying various theoretical frameworks to help students grow and develop academically, socially, emotionally, and personally. This includes understanding how students learn and develop, identifying various stages of development, and tailoring support and guidance to meet the unique needs of individual students. SDT is an interdisciplinary field that draws on psychology, education, sociology, and other areas to help educators and other professionals support the holistic development of students.
