The purpose of this descriptive and correlational study was to determine the extent to which irrational beliefs of students in early adolescents predict test anxiety. The study sample consisted of 557 students recruited from primary schools in Turkey. The Irrational Beliefs Scale for Adolescents (IBS-A) and the Test Anxiety scale were used as data-collection instruments. As a result of this study, there was a positive, significant correlation between mean scores on the Text Anxiety scale and total score, and the three subscale (demand for success, demand for comfort, and demand for respect) scores on the IBS-A. It was also found that demand for comfort and success are more statistically significant predictors of test anxiety levels of the students compared to demand for respect.
