The Council of Europe defines well-being as "the experience of health and happiness," encompassing mental and physical health, safety, belonging, sense of purpose, achievement, and success. Well-being varies depending on age and life stage, and it comprises different dimensions, including emotional, physical, social, workplace, and societal well-being.
Well-being is of paramount importance in educational institutions, be it at the elementary or high school level, and it applies to all students, teachers, administrative staff, and school administrators. The quality of school life, including well-being, is a critical factor in measuring a school's effectiveness and its impact on students' academic success and participation in the learning process.
