This paper proposes a theoretical framework for understanding childhood career development through five distinct stages, spanning from birth to early adulthood. Drawing on established theories of childhood development and career construction, we present a comprehensive model that articulates the progression of career-related skills, knowledge, and attitudes throughout childhood. The framework integrates key dimensions of career development, including the psychological self as actor, agent, and author; the formation of vocational identity; and the development of career adaptability. By delineating these stages, we aim to provide a foundation for designing age-appropriate career interventions and fostering a deeper understanding of the lifelong process of career development.
