This study examined marriage preparation among university students in Indonesia through Family Life Education (FLE). FLE was an educational program that aimed to develop knowledge, skills, and attitudes to foster harmonious family relationships and prevent family problems. The objectives were to assess students' knowledge of family life, identify key materials in FLE, and explore preferred program formats. Research data were collected from 56 University of Education Indonesia and Bandung Islamic University students using an online questionnaire via non-probability sampling, specifically voluntary sampling techniques. Data were analyzed using descriptive statistics and one-way ANOVA to explore differences in knowledge, material importance levels, and implementation preferences based on gender and age group. The study revealed that students were exceptionally knowledgeable about family law, roles, responsibilities, parental responsibilities, family dynamics, and money management, deeming these subjects essential for marriage preparation. Students preferred flexible FLE implementation (in-person, online, or blended), a minimum duration of 24 hours, qualified speakers, and certification. No significant differences were found based on gender or age. Integrating the FLE program into the university curriculum was considered crucial for students to acquire comprehensive knowledge, skills, and attitudes for responsible married life and family responsibilities.
