Organization

The Transportation Security Administration (TSA) was created to strengthen the security of the nation’s transportation systems and ensure the freedom of movement for people and commerce. Today, TSA secures the nation’s airports and screens all commercial airline passengers and baggage. TSA works closely with transportation, law enforcement and intelligence communities to set the standard for excellence in transportation security.

The Aviation and Transportation Security Act (ATSA, Public Law 107-71) requires the TSA to develop, implement, and manage training programs for its transportation security workforce. TSA comprises nearly 65,000 employees including approximately 50,000 Transportation Security Officers (TSO) as well as Transportation Security Inspectors (TSI), explosives experts, Federal Air Marshals (FAMS), Federal Flight Deck Officers, and law enforcement led canine teams that operate in the aviation, multimodal, maritime, mass transit, and cargo environments.
