The objective of the present study is to reveal the effect of the activity-based oral presentation course on the speech anxiety of Guidance and Psychological Counselling Department students. In the quantitative study conducted with a single group pre-test-post-test model, the data were collected with 'Speech Anxiety Scale for Pre-Service Teachers.' Based on the analysis conducted on the sub-dimensions of the above-mentioned scale, it was determined that students' post-test psychological state scores (x-bar = 3.976) were higher than pre-test psychological state scores (x-bar = 3.527), post-test physiological symptoms scores (x-bar = 4.034) were higher than pre-test physiological symptoms scores (x-bar = 3.791), post-test anxiety scores (x-bar = 3.744) were higher than pre-test anxiety scores (x-bar = 3.323) and post-test speech anxiety scores (x-bar = 3.957) were higher than pre-test speech anxiety scores (x-bar = 3.569). Based on this determination, several recommendations were made for the oral expression course.
