<![CDATA[Abstract: This study aims to analyze the effectiveness of applying Holland’s Theory in enhancing the career decision-making maturity of high school students. The research employs a qualitative method using a literature review approach, in which data were collected by examining various national and international studies published within the last five years, focusing on the influence of Holland’s theory on adolescents’ career maturity. Based on the analysis of several studies (Fitriyah et al., 2023; Desvikayati et al., 2022; Jiman & Dharsana, 2024; Tarmuzi et al., 2024), the findings indicate that Holland’s theory is effective in helping students develop self-understanding, identify their personality types based on the RIASEC model, and align them with appropriate occupational environments. Interventions derived from this theory—such as individual career counseling, interest and personality assessments, and career information services—significantly contribute to improving students’ career maturity. However, its effectiveness is influenced by contextual factors, including school and family support as well as the availability of valid assessment instruments. This review concludes that Holland’s theory remains relevant and adaptable to the dynamics of the modern world of work and can serve as a conceptual foundation for developing career guidance services in secondary education.
