Most national curricula include subjects that specifically target students' social and emotional skills, such as physical and health education, civic and citizenship education, and moral or religious education. Some countries also incorporate the development of social and emotional skills in the core curriculum. In addition, many OECD students participate in school governance and classroom management as alternative forms of extracurricular activities. These activities help students to develop the skills necessary for living in democratic societies, such as negotiating, teamwork and taking responsibility.
