# Threat Screening Center **Acronym:** TSC **Entity class:** Federal interagency screening center **Parent:** [[wiki/Federal Bureau of Investigation|Federal Bureau of Investigation]] ## Definition The **Threat Screening Center (TSC)** is the U.S. government's lead watchlisting and screening entity for terrorism-related identity information and an expanding set of national-security threats. It consolidates and shares identity information across federal screening systems and with authorized law-enforcement partners while maintaining the federal terrorism watchlist. The center was established in 2003 as the **[[wiki/Terrorist Screening Center|Terrorist Screening Center]]** after [[wiki/Homeland Security Presidential Directive 6|Homeland Security Presidential Directive 6]] ordered consolidation of the government's terrorism-screening approach. On March 19, 2025, the FBI renamed it the Threat Screening Center to reflect an expanded mission that includes [[wiki/Transnational Organized Crime|transnational organized crime]] alongside continuing terrorism watchlisting and screening. For [[wiki/Watchlist Misidentification|watchlist misidentification]], TSC is the authoritative coordination node at which ambiguous encounters are resolved, records are reviewed or corrected, and changes are verified across receiving screening systems. That role makes nomination quality, identity resolution, dissemination, redress, and correction latency parts of one distributed architecture. ## Relationships - **parent and partners:** [[wiki/Federal Bureau of Investigation|Federal Bureau of Investigation]], [[wiki/Intelligence Community|Intelligence Community]], and federal, state, local, tribal, territorial, and international screening partners. - **founding and expanded mission:** [[wiki/Homeland Security Presidential Directive 6|Homeland Security Presidential Directive 6]], [[wiki/Transnational Organized Crime|Transnational Organized Crime]], and [[wiki/Foreign Terrorist Organization|Foreign Terrorist Organization]]. - **legacy name:** [[wiki/Terrorist Screening Center|Terrorist Screening Center]]. - **systems:** [[wiki/Terrorist Screening Database|Terrorist Screening Database]], [[wiki/National Crime Information Center|National Crime Information Center]], and [[wiki/Watchlist Encounter Process|Watchlist Encounter Process]]. - **harm and correction:** [[wiki/Watchlist Misidentification|Watchlist Misidentification]], [[wiki/Watchlist Redress|Watchlist Redress]], [[wiki/Correction Latency|Correction Latency]], and [[wiki/Security Harms Topology|Security Harms Topology]]. - **collection:** [[collections/Terrorism, Counterterrorism, and the Intelligence Environment|Terrorism, Counterterrorism, and the Intelligence Environment]]. ## Sources / Provenance - [FBI — “The Terrorist Screening Center Changes Name to the Threat Screening Center”](https://www.fbi.gov/news/press-releases/the-terrorist-screening-center-changes-name-to-the-threat-screening-center) (2025-03-19). - [FBI — Threat Screening Center](https://www.fbi.gov/investigate/terrorism/tsc) (accessed 2026-09-23). - [FBI — Overview of the U.S. Government's Terrorist Watchlisting Process and Procedures](https://www.fbi.gov/file-repository/counterterrorism/terrorist-watchlisting-transparency-document-april-2024-050224.pdf/view) (2024-04; page updated to note the 2025 renaming). **As of:** 2026-09-23
