The present study examined the effects of gender and grade level on English reading comprehension proficiency of young Korean English as a Foreign Language (EFL) Learners. Through a nationwide reading comprehension assessment event, nine hundred seventy-nine young Korean EFL learners in Korean elementary school grades 1 through 6 were tested for their English reading comprehension measures. Statical analysis was conducted to investigate between and within group differences as well as possible interactional effect of gender and grade level. Results showed significant main effects of gender and grade level on reading comprehension. However, there was no interactional effect of gender and grade level on English reading comprehension of the young Korean EFL learners.
