The 2010 HAP Standard is the result of an extensive revision of the 2007 edition based on wide-ranging consultations with stakeholders. Over 1,900 people contributed to the review and the preparation of the 2010 edition. During this process, the HAP Secretariat sought input from quality and accountability initiatives, including the Sphere Project, People in Aid, the Australian Council for International Development, and the UK Disasters Emergency Committee. The Plain English Campaign reviewed several drafts for language accessibility.
