Introduction: The concept of the health promoting school offers a coherent approach to promoting health and well-being within a whole school community. This study sought to evaluate the health programmes and policies adopted by different Lebanese schools, and their appropriateness for this role as part of health promotion. Methods: Our research took the form of a prospective observational study involving 50 schools from different areas of Lebanon. Data were collected using a questionnaire based on the Health Assessment Tool for Schools (HATS). Data were analysed to describe school characteristics and to reveal differences in the health topics addressed. Results: Most of the schools included in the study came from Mount Lebanon (56%). Around 70% of the involved schools offered health-related courses in their curricula. Health-related seminars and workshops (60%) and health awareness campaigns took place at the studied schools, with 98% incorporating physical education into the curriculum. Dental health (74%), smoking cessation (72%) and physical activity (68%) were among other most addressed topics, while mental health was the least discussed (20%). The majority (70%) of schools had a shared vision of what promoting health involved and sought to promote the active involvement of community members in the life of the school (60%). Around two-thirds of the schools (66%) provided physical support and facilities, and had developed policies for health promotion. Less than half of these schools' health committees, however, had developed plans to improve health promotion and review data to ensure the effectiveness of their programmes. Conclusion: The study findings suggest that despite weaknesses, the majority of the sampled schools had either implemented or were in the process of implementing a health promoting school programme to improve health education and students' well-being.
