The utilization of intergenerational relationship as the foundation for community development aligns with the expectations set forth by Thailand's national policies, particularly within the economic dimension. This research explores the outcomes of fostering intergenerational relationship and investigates the learning outcomes to create fresh significance in the collaborative occupational development of diverse age groups. It involves the experimental implementation of the Intergenerational Relationship Program aimed at redefining the meaning of community development in the Thai context, with a specific focus on youths and elderly demographics within Ban Na, Nakhon Nayok Province, involving a total of 60 participants. To assess the study's outcomes, different methods were employed, such as surveys and interviews, followed by data analysis to expound upon the observed results. The research findings indicate a positive trend in intergenerational relationship, with enhanced communication between youths and the elderly, increased communal engagement, improved mutual attitudes, and a greater display of friendliness towards one another. Regarding learning outcomes, it was found that the collaborative grouping of individuals from two different age brackets led to the development of community-generated products with inherent value. Additionally, the target groups stated that program participation had the potential to increase community livelihoods and income generation.
