The distinctive curriculum system serves as the core vehicle for private vocational undergraduate design programs to demonstrate their educational strengths and enhance talent cultivation quality. However, some programs currently face challenges such as unclear implementation pathways, insufficient support mechanisms, and overly simplistic evaluation methods for educational outcomes, which hinder the realization of specialized educational goals. This study focuses on private vocational undergraduate design programs to define the connotation and implementation principles of distinctive curriculum systems. It explores implementation strategies across five dimensions: curriculum implementation, teaching reform, practical support, faculty resources, and evaluation optimization. By analyzing educational effectiveness through three dimensions—student competencies, professional development, and social service contributions—this research proposes strategies for enhancing outcomes. The findings provide theoretical references and practical paradigms for the effective implementation of distinctive curriculum systems and the improvement of educational quality in private vocational undergraduate design programs.
