To raise a child, parents need the support of others, including other family members, other groups, governments, and schools, to help individuals achieve the developmental tasks across the lifecycle. Other groups include informal groups such as friends and neighbors, and formal groups such as nonprofit organizations, religious groups, and commercial enterprises. Schools are a primary means of providing cognitive, social, and physical skills. Schools at all levels explicitly teach academic skills and provide opportunities to develop other types of skills in classes and extra-curricular activities including clubs, music groups, and athletics. But they can also explicitly teach additional skills, such as those involved in social intelligence and emotional intelligence. This can include information literacy, science as a way of knowing, problem-solving, career planning, and teamwork.
