The study was conducted to assess the implementation of Philippine Early Childhood Development Program on kindergarten pupils of New Society Central Elementary School as basis for a proposed teachers’ ECCP enhancement plan. It is important to note that due to the limited participants in this study, the results of this research may not necessarily be generalizable to all schools with kindergarten curriculum for this is only focused on kindergarten students of New Society Central Elementary School during school year 2020-2021. The selection of participants was done through universal sampling and all kindergarten pupils of New Society Central Elementary School during the school year 2020-2021 were onboarded as subjects of the study. Data-gathering permissions were secured from department head of the graduate school of RMMC, as well as from the school administrator where the study was conducted. This research utilized the assessment of ECCD of the respondents, specifically assessment 1 and assessment 2. Based on the result, it was found out that the implementation level of Philippine Early Childhood Education Development Program was generally high for all domains, namely: gross motor; fine motor; self-help; receptive language; expressive language; cognitive; and socio emotional. Thus, a proposed teachers’ ECCP enhancement plan was designed by the researcher based on the results of the study, which focused on three least-improved domains.
