A Tentative List is an official list developed by each signatory to the UNESCO World Heritage Convention, as required by the World Heritage Committee, of properties that are believed by a country to meet the criteria for World Heritage listing and from which a country may make nominations to the World Heritage List. Only properties included on the U.S. Tentative List are eligible for nomination by the Department of the Interior. Inclusion on the Tentative List does not, however, guarantee future nomination.
The U.S. National Park Service (NPS) has announced plans to update the U.S. Tentative List for the first time since the current one was developed and formally submitted to the World Heritage Committee in 2008. At the time it was developed, the 2008 U.S. list included 14 properties or groups of properties from among 35 that submitted applications to the Department of the Interior. Five of these properties have since been nominated: Three have been successfully included on the World Heritage List, one was withdrawn after nomination, and one nomination is pending. The NPS has said that sites remaining on the current tentative list will be invited to remain on the revised Tentative List if they are interested to do so.
