Service learning has picked up momentum in the engineering education field over the past decade due to its two pronged benefits to the students’ learning experience as well as to the community. While it is usually embedded within the curriculum in terms of execution, the Taylor’s Grand Challenge Scholars Programme (TGCSP) runs it in parallel with formal curriculum. TGCSP was developed to nurture holistic engineers capable of addressing the grand challenges defined by the National Academy of Engineering (NAE), USA, which stand in the way for humankind’s survival of the next century. Service learning is the fifth programme outcome (GCPO5) of TGCSP which scholars must attain in order for them to be able to graduate with TGCSP certification which is endorsed by NAE. This paper outlines the structure of implementation and assessment of GCPO5. In addition, the scholars’ perception on how their journey towards attainment of GCPO5 has impacted their learning experience will also be discoursed.
