The purpose of this manual is to provide a resource for training to increase understanding of Health in All Policies (HiAP) by health and other professionals. It is anticipated that the material in this manual will form the basis of two- or three-day workshops, which will: • Build capacity to promote, implement and evaluate HiAP; • Encourage engagement and collaboration across sectors; • Facilitate the exchange of experiences and lessons learned; • Promote regional and global collaboration on HiAP; and • Promote dissemination of skills to develop training courses for trainers.
