New treatment materials and procedures are continually being sought and evaluated. Facsimiles of possible methods or materials are frequently made and tested in order to support treatment choices. Accelerated aging tests are regularly carried out as another method to try to evaluate materials for treatment and storage use. The field of Conservation Science further supports and informs conservation treatment, as part of its function is to perform more advanced analytical assessments than can be routinely carried out in most conservation laboratories. In the area of preventive conservation, Anthropology Division conservators work with collections managers, exhibition staff and curators to formulate and help implement standards for safe exhibit, travel, and storage environments; for pest control; for handling and maintenance procedures; and for emergency preparedness and response - all of which will help mitigate against deterioration and damage of the collections. The Anthropology Division objects conservation staff currently consists of four permanent conservators who have received graduate level training. For large projects additional staff members are added as required. The laboratory regularly provides internship training to individuals registered in or who have completed formal graduate training in conservation.
