Communication apprehension has been identified as a major factor which inhibits an individual's willingness to communicate and his/her ability to develop effective communication skills. While many prior studies have investigated oral communication apprehension among undergraduate students, there has been little research exploring this phenomenon among doctoral students. This study applied qualitative methodology via observation and interviews. The research subjects were international doctoral students from several Malaysian universities. The experiences of the students in communicating with examination panel during academic presentations (e.g. proposal and viva) are analysed and the factors contributing to their oral CA are explored.
