Maintaining sound reproductive health is crucial for achieving and sustaining optimal overall well-being. Reproductive health encompasses various physical, emotional, and social factors that significantly impact an individual's quality of life. The present study used a descriptive-correlational research design to determine and explore the relationships between teacher education students' knowledge, attitudes, and practices (KAPs) on reproductive health in a state university in Zambales, Philippines. A total of 146 respondents completed the online survey questionnaires. Findings showed that teacher education students have a moderate level of knowledge on reproductive health, including the basic components of the reproductive system, the transmission of reproductive diseases, the influence of the environment on reproductive health, and birth control methods. Respondents have very favorable attitudes towards reproductive health in terms of reproductive health education and services. They often practice various activities related to reproductive wellness, reproductive hygiene, and reproductive health resources. When respondents were grouped based on age and year level, their practices showed significant differences. The study reveals a low positive correlation between respondents' knowledge and attitude towards reproductive health. Documenting teacher education students' KAP is a useful basis for science curriculum enhancement in education institutions to improve students' KAPs regarding reproductive health.
