The main aim of this study was to investigate the correlation among test anxiety (TA), foreign language anxiety (FLA) and language achievement of university preparatory students learning English as a foreign language. The sample of the research consisted of 301 (211 females, 90 males) attending a one-year EFL preparatory school at Ondokuz Mayis University, School of Foreign Languages. The TAI (Test Anxiety Inventory) developed by Spielberger (1980), FLCAS (Foreign Language Classroom Anxiety Scale) developed by Horwitz (1986) and the students' language achievement scores were used to collect data. In addition, this study aimed to determine the effect of gender on both TA and FLA. The findings of the study revealed that there was no relation between students' TA and their language achievement. It was also found a significant positive correlation between students' TA and FLA. Besides, the result demonstrated that there was a significant reverse correlation between students' FLA and their language achievement. Following t-test results, it was found out that females exhibited higher mean scores than males in both TAI and FLCAS. Finally, certain suggestions were set for EFL teachers to reduce text anxiety and language learning anxiety in foreign language classroom settings.
