Higher education institutions (HEIs) fulfil threefold functions: instruction, research, and extension. The third function which is community extension used to play a supporting role and performed within the context of accreditation. Ideally, it must be integrated into the academic fabric of the institution. The objective of this study was to examine the impact on the human security of its beneficiaries, especially on their economic, food, health, environmental, personal, community and political security, of the Children’s Education Welfare Assistance (CEWA), a 15-year community-based program of a higher education institution in the Philippines. CEWA simultaneously carried out three sub-programs: Child Development, Family Development, and Institution Building. A multilevel mixed method was used to gather data on three levels: Sponsored Children, Sponsored Family, and Program Implementer. Documents, Survey Questionnaire, FGD, and KII were used for data collection. A researcher-made questionnaire was deployed after it had been submitted to content expert validation, pilot and reliability testing. Respondents were selected using a purposive sampling technique. Data were analysed using document analysis, paired-samples t-test, and direct content analysis. Overall, the programs of CEWA have had an immense impact on the economic, food, health, environmental, community, personal, and political security of the beneficiaries. Community extension initiatives that are long-term and holistic in approach can be an effective agent of societal transformation.
