The study aimed to develop and propose a capability enhancement program for public elementary school science teachers in District 1-A, San Carlos City Division. The findings revealed that the respondents were mostly in the process of pursuing their masters’ degree; non- science major; relatively young or just have short teaching experience in teaching Science; and most of them had attended Division training in Science. Further findings had shown that the public elementary school science teachers are “Highly Capable” on Learning Environment and “Capable” on Content Knowledge and Pedagogy, Diversity of Learners, Curriculum and Planning, and Assessment and Reporting, domains based on the PPST. In addition, educational attainment and area of specialization were not significantly related to their level of capability in the five domains of PPST while the length of service of science teachers was not significantly related to the learning environment, curriculum and planning. However, it is related to the domains Content Knowledge and Pedagogy, Diversity of Learners and Assessment and Reporting which indicated “Moderate Relationship”. Lastly, on the level of trainings in Science attended, only Domain 2 Learning Environment was found to have no significant relationship with the level of trainings in science attended. However, the level of trainings has a “strong positive relationship” with the domains on Content Knowledge and Pedagogy, Diversity of Learners, Curriculum and Planning and Assessment and Reporting.
