T his quasi-experimental study of one group design attempted to explore how far National Conversation Forums (NCFs ) – as a proposed teaching strategy – can develop  EFL university students' critical speaking skills.

Nine Saudi  EFL students at KKU, Saudi Arabia constituted the participants of the study. Data was collected from one source: a public speaking test for assessing critical speaking skills. The findings revealed a positive significant  impact of NCFs on developing critical speaking skills in social issues-based language contexts.
