Purpose: This study aims to explore the psychological determinants that shape the development of professional skills among future preschool education staff, emphasizing the role of personal qualities and psychological factors in professional preparedness.

Research Methodology: The research is based on a systematic review and synthesis of scholarly works from CIS and international contexts. It analyzes motivational, cognitive, emotional, and communicative dimensions that influence competence building in preschool education.

Results: The findings indicate that responsibility, independence, initiative, creative thinking, empathy, and social activity significantly enhance the formation of professional competencies. Moreover, the integration of “hard skills” and “self skills” strengthens readiness for practice, while empathy and sociability play an essential role in effective collaboration with children and their parents.

Conclusions: Psychological determinants are strongly interconnected with professional motivation, flexibility of thinking, and emotional values, making them crucial for the effective preparation of future specialists in preschool education.

Limitations: The study is conceptual in nature and does not include empirical testing. Future research should incorporate field studies and experimental designs to validate these determinants in practical contexts.

Contribution: This article contributes to educational psychology and teacher training literature by highlighting the psychological basis of skill formation, offering insights for improving professional training programs for preschool education staff.
