Objective: This study aims to examine the influence of university image, electronic word of mouth (eWOM), and digital marketing on students' enrollment decisions in private higher education institutions (PHEIs) in West Java, Indonesia. Method: Grounded in the Theory of Planned Behavior, Information Processing Theory, and Social Influence Theory, this study employed a quantitative research design. Data were collected from 200 prospective students using purposive sampling and analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM) to evaluate the relationships among the proposed constructs. Results: The findings reveal that university image (β = 0.312; p < 0.001), eWOM (β = 0.285; p < 0.001), and digital marketing (β = 0.247; p < 0.001) have positive and significant effects on students’ enrollment decisions. Among the predictors, university image emerged as the strongest determinant. The structural model explains 68.4% of the variance in enrollment decisions (R² = 0.684), indicating substantial predictive capability and confirming the importance of both institutional reputation and digital communication channels in influencing prospective students’ choices. Novelty: This study contributes to the higher education marketing literature by simultaneously integrating university image, eWOM, and digital marketing within a single SEM-PLS framework. Unlike previous studies that examined these factors separately, this research provides a comprehensive model contextualized for Generation Z prospective students in Indonesia, offering a more holistic understanding of enrollment decision-making in the digital era.
