Earlier research has shown that fair assessment plays a crucial role in the classroom and is closely associated with students' academic success. Besides, multiple studies have consistently indicated that the cognitive aspect of test anxiety significantly and meaningfully influences test performance, highlighting the connection between test anxiety and academic achievement. Therefore, this correlational study was done to investigate the relationship between Iranian EFL learners' perceptions of fairness in classroom assessment and their cognitive test anxiety. It followed a quantitative method and a total number of 201 learners, 88 males along with 113 females, participated in the present study voluntarily. A convenience and random-sampling method were applied, using fair assessment and cognitive test anxiety questionnaire. The results of the study, using Pearson-moment correlation and Regression analysis, revealed that there was no significant relationship between Iranian EFL learners' perceptions of fairness in classroom assessment and their cognitive test anxiety. It also indicated no significant difference between male and female learners' perceptions of fairness in classroom assessment and their cognitive test anxiety. The findings of the study can be implemented in educational systems by teachers, learners, programmers, and researchers. It can be considered as a guideline for teachers, especially EFL teachers in academic environments to find solutions for the problems and difficulties in the fairness of classroom assessment.
