This guide is a revision of Sexuality Education: A guide for principals, boards of trustees, and teachers (2002). The guide will assist boards of trustees, principals, and teachers in all New Zealand state and state-integrated schools to comply with the requirements of the Education Act 1989 (as amended in 2001) to consult with the school community on the way in which the health curriculum should be implemented. The Health Select Committee report, Inquiry into improving child health outcomes and preventing child abuse with a focus from preconception until three years of age (November 2013) highlighted the importance of quality sexuality education programmes for all young people and the need for access to health services. This revision takes into account that report, along with other interagency work to prevent violence. The revision also takes account of changing social climates, recent youth health research, and broader understandings about sexuality and sexuality education.
