This study investigates the immediate impacts of online Service-Learning (SL) on partner communities in the Philippines, addressing a gap in existing literature focused on face-to-face (f2f) SL engagements. Using a mixed-method convergent design, it assesses benefits, drawbacks, and factors influencing the effectiveness of online SL. Data was collected from 66 key contacts across 36 community partner organizations (CPOs) of a comprehensive university using a survey questionnaire and 11 individual interviews. Results show that online SL projects generally support CPOs' missions, enhance resources, foster new knowledge, and yield positive outcomes. However, qualitative analysis reveals areas for improvement to make online SL more engaging and responsive to community needs. This research emphasizes the importance of examining the immediate impact of online SL, guiding best practices for implementation, and fostering effective online SL collaborations that can be adapted across various countries with similar contexts.
