Guidance on the World Heritage Convention is produced by UNESCO World Heritage Centre supported by its advisory bodies:
International Union for Conservation of Nature (IUCN) provides the World Heritage Committee with technical evaluations of natural and mix heritage properties such as inscriptions and reports on the state of conservation of listed properties.
International Committee on Monuments and Sites (ICOMOS) provides the World Heritage Committee with technical evaluations of cultural and mix heritage properties such as inscriptions and reports on the state of conservation of listed properties
International Center for the Study and Restoration of Cultural Property (ICCROM) is an intergovernmental organization, which provides the Committee with expert advice on conservation of cultural sites, as well as on training activities.
Updated guidelines can be found in the Operational Guidelines for the Implementation of the World Heritage Convention.
Protection and management of World Heritage properties should ensure that the Outstanding Universal Value, including the conditions of integrity and/or authenticity at the time of inscription, are sustained or enhanced in future. A regular review of the general state of conservation of properties, and thus also their Outstanding Universal Value, shall be done within a framework of monitoring processes for World Heritage properties as specified in the Operational Guidelines (OG 96).
