 In places where the appropriate contacts and stakeholders are less obvious, community archaeologists attempt to identify as many interest groups as possible and contact them before research begins.A top-down approach to community archaeology is when archaeologists decide before consultation what the goals of the project will be, or what benefits will be provided to the community is not really community archaeology at all.The top-down approach creates a one-sided exchange of information from the archaeologists to the community and precludes real collaboration.
