Despite the numerous studies investigating the nature of anxiety and its relationship with several age groups in the context of foreign language classroom anxiety, these two subjects are still in need of further quantitative investigation. Accordingly, the current study investigated the major factors that lead to students' foreign language classroom anxiety levels, and the possible relationship between anxiety and age. To do this, Horwitz's (1986) Foreign Language Classroom Anxiety Scale (FLCAS) was distributed to the third-year students of the English Language and Literature Department of a state university in the Oral Communication II course. The data obtained were investigated by both descriptive and inferential statistical procedures to reveal the major factors of foreign language classroom anxiety and its possible relationship with age. The results indicated unusual findings which are due to be beneficial for the interests of foreign language teaching researchers.
