This study analyzes intellectual disabilities among secondary school students in the Kabongo 2 subdivision. The main objective is to identify the types of disabilities observed, their causes, and their effects on academic achievement. The methodology employed is based on a descriptive and analytical approach, using questionnaires and interviews with teachers and students. The results show that the most frequent disabilities involve memory, comprehension, and logical reasoning. These disabilities stem from socioeconomic, pedagogical, and psychological factors. Intervention strategies are proposed, including teacher training, psychological support, and the adaptation of teaching methods.
