To respond the globalization, the importance of English communication skills including speaking skill increases. Looking at Indonesian context, secondary high school students find spoken English much more difficult than written English. Students are good at grammar, reading, and writing but they can hardly speak (Hairdara, 2016). This article proposes collaborative learning approach (CLA) as one suitable solution to solve the obstacles of sharpening English speaking skill due to its benefits. The discussion of this investigation highlights some benefits of CLA in developing speaking skill and the challenges need to be considered as well. Receiving well proven evidence of its benefits, CLA is recommended to be implemented in the teaching and learning of English speaking skill. As the results of this investigation, there are three main benefits of CLA whose implementation can reduce language anxiety, raise students' participation, and increase students' self-confidence.
