What does twice-exceptional mean?
Many gifted people also have some form of disability. This may be a physical or sensory disability, or a form of neurodivergence, like ADHD or autism.
This is called being twice-exceptional, or 2e.
Many people who are twice-exceptional need additional support, especially in education settings.
