This paper documents the CDIO peer-to-peer support (P2PS) experience between 2 peers, that is Singapore Polytechnic (SP) and Batangas State University (BatStateU). First, the CDIO P2PS initiative is introduced along with an overview of the previous work that laid the ground work for this P2PS experience. This foundational work enabled both institutions to enhance education for sustainable development through sharing of expertise. Then, the paper provides a brief comparison between CDIO P2PS and existing learning communities. CDIO P2PS stands out due to its unique structure, specifically, it involves two educational institutions that are committed to learning from each other’s educational practices and aligned with the CDIO Framework which further promotes ongoing and future collaboration. The paper also elaborates on the learning points gathered from the participants at both SP and BatStateU. These insights highlight the positive outcomes and benefits experienced by both institutions as a result of this P2PS. The open-mindedness and responsiveness of both peers played a significant role in the overall success. In conclusion, this CDIO P2PS experience is deemed a resounding success for this collaboration not only enhances the educational practices at both institutions but also sets a precedent for future peer-to-peer support initiatives.
