Thai coffee farmers have exerted much effort to develop GAP-based Robusta coffee production since 2008. However, they still lacked knowledge and experience. Their conventional farming activities are often in conflict with GAP system, which might be caused by the limitation of GAP extension procedure. The objectives of this study were to investigate the current perceptions of GAP Coffee Farmers (GCF)’s understanding of GAP, and to identify the factors affecting such perceptions. A series of surveys were conducted in Chumphon province by using structured questionnaires which were administered to fifty-six (56) coffee farmers who applied for GAP certificates in 2013. This study found that farmers’ GAP self-confidence positively affected, while farmers’ GAP experiences had negative impact to the farmers’ understanding of GAP. This showed the lacking of continuity of GAP extension service, although the GAP promotion was an important factor to increase the farmers’ GAP understanding. The very small number of agricultural extension officers was cited as a detrimental factor. The GAP manual should also be simplified to suit the GCFs educational background.
