This study aimed to examine the effects of different text difficulty levels on foreign language reading anxiety (FLRA) and reading comprehension of English as a Foreign Language (EFL) learners. To this end, 50 elementary EFL learners were selected from two intact classes (n = 25 each). Each class was assigned to a text difficulty level (i.e., "i + 1" and "i - 1") in which the participants experienced extensive reading at different levels of difficulty for two semesters. A reading comprehension test and the Foreign Language Reading Anxiety Scale (FLRAS) were administered before and after the treatment. The results revealed that both text difficulty levels significantly improved the participants' reading comprehension. The findings also showed that, at the end of the study, the "i + 1" group's FLRA increased, while that of the "i - 1" group decreased.
