The purpose of the New York City Trafficking Assessment Project (NYCTAP) was to develop a screening tool to identify likely victims of trafficking and an accompanying toolkit for service providers to support the administration of the screening tool. The NYCTAP Community Advisory Board (CAB) consisted of twelve local organizations, including four social service agencies, four legal service agencies, three community-based organizations, and one advocacy organization. In May and June of 2007, (Part 1, Community Advisory Board (CAB) Agency Reviews Qualitative Data) a draft of the screening tool was circulated among the CAB agencies for review. The reviewers were asked to evaluate the screening tool for comprehensiveness, section organization, question wording, and question placement. The draft NYCTAP screening tool was also circulated among law enforcement agencies at the federal and local level in November and December of 2007. Reviewers (Part 3, Law Enforcement Agency Reviews Qualitative Data) were asked to review the screening tool from the perspective of federal and local law enforcement and to suggest modifications and additions to screening tool content. In October and November of 2007, semi-structured interviews (Part 2, Community Advisory Board (CAB) Agency Interviews Qualitative Data) were conducted with two CAB agencies that were unable to participate in the field application of the screening tool, but had extensive experience in trafficking victim assistance that could be shared. In January and February of 2008, (Part 4, Community Advisory Board (CAB) De-briefings Qualitative Data) six of participating CAB agencies that applied the draft NYCTAP screening tool in their work with clients were asked to provide feedback on the overall usability of the screening tool, as well as tool content and tool administration.
