Borderline intelligence individuals do not fall under the category of general intellectual disabilities but are a group who experience difficulties in daily life, accounting for 5.1% of children and adolescents and 6.8% of adults. They have a higher risk of dropping out of school or social isolation and their rate of psychiatric drug use is more than six times higher than the general population. Borderline intelligence individuals face various hardships such as employment instability and parenting burdens, making the urgent need for related legislation and the establishment of a dedicated support system. In particular, early detection and individualized customized education support, vocational training, and self-reliance support policies are necessary.
