From my experience, children as young as 7 or 8 can benefit from social skills courses, especially ones like the 8-Week Social Skills Journey for Kids offered by Rocky Mountain Psychological Services. These courses are tailored to meet the needs of younger children, focusing on things like empathy, sharing, and positive peer interactions. Older children and teens can also benefit from social skills courses, especially those that focus on more complex aspects of social dynamics, like conflict resolution and leadership.
