This study investigates the impact of gender and grade level on students' general intelligence, verbal potential, visual potential, and memory capacity. The participants of the study consist of 4063 students who applied Anadolu University Center for Research and Practice for High Ability Education (EPTS) for intelligence test administration between the years 2017 and 2021. To determine the students’ general intelligence, verbal potential, visual potential and memory capacity, Anadolu Sak Intelligence Scale (ASIS) was used. To examine the impact of gender and grade level on students' general intelligence index (GIQ), verbal potential index (VEPI), visual potential index (VIPI), and memory capacity index (MCI), 2x3 ANOVA was carried out. The results showed that the joint interaction of gender and grade level variables significantly impacts all index scores except for VIPI (p<.05). In other words, gender and grade level variables together are determinants of GIQ, VEPI, and MCI scores. In conclusion, this study reveals that males and females exhibit differences in specific cognitive abilities. Furthermore, it is noteworthy that the averages of primary school students are lower than the averages of preschool students in general intelligence and in each of the indices (VEPI, VIPI, MCI).
