TSA Law Enforcement Careers: Federal Air Marshals, Leadership and Investigations
TSA’s principal law-enforcement organization is the Law Enforcement/Federal Air Marshal Service, commonly abbreviated LE/FAMS. Its best-known operational position is Federal Air Marshal, but the organization also includes field-office leadership, airport law-enforcement liaison, mission operations, incident-response and executive roles.
TSA also employs Criminal Investigators. That title can sound like a direct branch of the Federal Air Marshal career ladder, but TSA’s current public career taxonomy places Criminal Investigator within Mission Support, while Federal Air Marshal positions remain within LE/FAMS. Both can involve federal investigative or enforcement work, yet their occupational series, daily work, hiring routes and career structures are not interchangeable.
This page compares the paths before sending you to the detailed role and assessment guides.
Law-enforcement requirements are vacancy specific. Age rules, veteran exceptions, covered-service credit, pay bands, physical standards, polygraph requirements, clearance levels, mobility conditions and training can change. The active Job Opportunity Announcement and your official instructions always control.
Choose the Career by the Work, Not the Title
Choose Federal Air Marshal when you want operational armed law enforcement
Federal Air Marshals protect civil aviation and the wider transportation domain through air- and ground-based assignments. The career requires firearms responsibility, extensive travel, irregular schedules, physical readiness, a law-enforcement polygraph and national-security vetting.
Choose LE/FAMS leadership when you already have qualifying operational experience
Supervisory Federal Air Marshal, Assistant Supervisory Air Marshal in Charge and Supervisory Air Marshal in Charge positions lead people, field offices and operational programs. These are competitive advancement roles, not separate entry-level occupations.
Choose AFSD-Law Enforcement when you want airport liaison and coordinated operations
The Assistant Federal Security Director for Law Enforcement connects airport security leadership with the LE/FAMS field-office chain and external law-enforcement partners. Recent vacancies have required substantial FAM and liaison experience, Top Secret eligibility and extensive travel.
Choose Criminal Investigator when you want case-development work
Criminal Investigators build criminal or administrative cases through evidence, interviews, records, legal coordination and investigative reports. TSA currently lists Criminal Investigator among Mission Support roles, even though federal criminal-investigation positions commonly use occupational series 1811 and can carry separate law-enforcement conditions.

Federal Air Marshal
Federal Air Marshal is TSA’s main operational law-enforcement position. FAMs are deployed according to risk and mission needs to protect commercial aviation and other elements of the transportation system.
Publicly described responsibilities can include:
- protecting domestic and international commercial flights;
- assessing and responding to transportation threats;
- working independently in high-consequence environments;
- conducting law-enforcement activity authorized by federal law;
- supporting Visible Intermodal Prevention and Response operations;
- participating in Joint Terrorism Task Forces;
- supporting major incidents and natural-disaster response;
- coordinating with federal, state, local and international partners;
- working in airport liaison, training, headquarters or mission-operations assignments;
- maintaining firearms and physical proficiency; and
- protecting classified information, law-enforcement-sensitive information and Sensitive Security Information.
Specific routes, flight coverage, tactics and deployment methods are not appropriate subjects for public discussion.

Federal Air Marshal Hiring Profile
Recent public entry-level recruitment has required candidates to meet conditions including:
- U.S. citizenship or U.S. national status;
- age 21 or older at application;
- entry on duty before the 37th birthday unless a documented exception applies;
- qualifying experience, education or an accepted combination;
- a valid driver’s license;
- a valid U.S. passport and government travel card under recent recruitment;
- successful Federal Air Marshal Assessment Battery results;
- a Physical Ability Test;
- job-related medical qualification;
- pre-employment drug and alcohol screening;
- a favorable law-enforcement polygraph result;
- a comprehensive background investigation;
- Top Secret eligibility;
- ability to carry a firearm and use authorized force;
- acceptance of constant travel and irregular duty; and
- completion of required resident law-enforcement training.
Qualifying preference-eligible veterans and applicants with prior covered federal civilian law-enforcement service can receive different age treatment when the announcement permits it and the required documentation is submitted.
A TSO can apply to a FAM vacancy when eligible and qualified. TSO service creates no automatic transfer and does not waive FAB, PAT, medical, polygraph, clearance, firearms or training requirements.
Federal Air Marshal Assessment Battery
The Federal Air Marshal Assessment Battery, or FAB, is different from the TSO assessment. TSA’s official manual identifies:
- Logic-Based Reasoning;
- Writing; and
- Video-Based Situational Judgment, including judgment and observation tasks.
TSA’s manual states that incorrect answers are not penalized. Logic and Writing answers can be reviewed when time remains, while a candidate cannot return to an earlier Situational Judgment item after advancing.
Start with the free Federal Air Marshal FAB study guide.
Candidates who need more practice after completing the official examples can review this Federal Air Marshal test-preparation package. The course is optional and cannot guarantee a passing result or appointment.
Our JobTestPrep Federal Air Marshal review explains the package’s current Logic, Writing and SJT coverage, along with its stated limitation for dedicated Observation Skills practice.
Physical, Medical, Polygraph and Clearance Stages
The law-enforcement process is not one assessment followed by an offer.
Physical Ability Test
Recent entry-level FAM recruitment used a pass/fail PAT requiring:
- at least 31 sit-ups in one minute;
- at least 29 push-ups in one minute; and
- a 1.5-mile run in 16 minutes 31 seconds or faster.
The current invitation controls if the standard changes. See the Federal Air Marshal physical-test guide.
Medical evaluation
Medical review is separate from the PAT and evaluates the ability to perform armed, physically demanding and travel-heavy work. Passing one does not establish qualification for the other.
Polygraph
TSA’s current federal hiring page lists a polygraph examination as a Law Enforcement requirement. Recent FAM recruitment required a favorable pre-employment law-enforcement polygraph result.
See the Federal Air Marshal polygraph guide.
Background and clearance
Recent operational FAM and AFSD-LE vacancies have required Top Secret eligibility and Critical-Sensitive/High Risk processing. Review can address identity, citizenship, criminal history, finances, drug and alcohol conduct, employment, foreign contacts, references, judgment and reliability.
A prior clearance does not automatically transfer. See the TSA security-clearance guide and TSA background-check guide.
FAM Assignments Beyond In-Flight Missions
Federal Air Marshals do not spend every phase of a career performing one identical assignment.
Visible Intermodal Prevention and Response
VIPR operations use a visible law-enforcement and security presence to detect and deter suspicious or dangerous activity across transportation modes. Assignments can involve coordination with local and federal partners.
Critical Incident Response Program
TSA describes CIRP as a response capability for major events and natural disasters. FAMs can support law-enforcement partners in the United States or abroad.
Mission Operations Control
FAMs can serve in mission-operations roles at the Transportation Security Operations Center in the Washington, D.C. area. These assignments support threat monitoring and operational coordination.
Joint Terrorism Task Forces
Qualified FAMs can serve with JTTFs, contributing transportation expertise to multi-agency terrorism investigations and intelligence coordination.
Airport law-enforcement liaison
Experienced FAMs can serve in airport liaison and AFSD-Law Enforcement roles connecting the Federal Security Director’s organization, LE/FAMS leadership and outside law-enforcement agencies.
Assignment availability depends on organizational need, experience, performance, vacancy and selection. A new FAM should not expect immediate choice of a preferred specialty or location.
Federal Air Marshal Leadership
Supervisory Federal Air Marshal
Supervisory FAMs direct employees and operational work. Competitive applicants need evidence of sound law-enforcement judgment, mission planning, employee development, policy implementation, incident management and accountability.
Assistant Supervisory Air Marshal in Charge
ASAC positions help direct a field-office group, program or operational function. Duties can involve personnel management, mission oversight, partner coordination and execution of LE/FAMS priorities.
Supervisory Air Marshal in Charge
The SAC leads an LE/FAMS field office. TSA classifies SAC as a Transportation Security Executive Service position. The role oversees the planning, direction and coordination of FAMs deployed on flights and in ground-based assignments.
SAC is not an automatic promotion based only on years of service. It requires executive-level leadership evidence and selection through the applicable TSES process.
Assistant Federal Security Director – Law Enforcement
AFSD-LE is a bridge between TSA airport leadership and LE/FAMS field-office command.
A recent TSA vacancy described the role as:
- establishing and maintaining liaison with law-enforcement authorities;
- coordinating activities across the transportation-security domain;
- receiving operational direction from the Federal Security Director;
- reporting to the LE/FAMS field-office SAC for personnel and law-enforcement matters;
- supporting law-enforcement and security coordination at assigned airports; and
- accepting extensive travel, Top Secret eligibility and drug-testing requirements.
The recent vacancy used series 1801 and TSA pay band SV-J. That example should not be treated as a permanent national pay promise; location, band and conditions depend on the active announcement.
AFSD-LE normally requires substantial existing law-enforcement and FAM experience. It is not an external entry-level alternative to Federal Air Marshal.
Criminal Investigator
TSA Criminal Investigators can conduct criminal and administrative investigations involving employees, contractors, regulated entities, civilians and suspected violations of federal law.
Their work can include:
- receiving and evaluating allegations;
- planning investigations;
- interviewing witnesses, subjects and complainants;
- collecting and preserving evidence;
- reviewing records and electronic information;
- coordinating with prosecutors, counsel and other agencies;
- preparing affidavits, reports and case files;
- presenting findings; and
- supporting administrative, civil or criminal action.
Read the TSA Criminal Investigator guide for role-specific qualification and resume guidance.
Why TSA Criminal Investigator Is Not the Same Path as FAM
The positions can overlap in law-enforcement knowledge, but their core work differs.
| Factor | Federal Air Marshal | Criminal Investigator |
|---|---|---|
| Primary focus | Operational protection and transportation threat response | Development of criminal or administrative cases |
| Common classification | TSA SV system, commonly series 1801 | Commonly federal series 1811 or vacancy-specific equivalent |
| TSA public career category | Law Enforcement/FAMS | Currently listed under Mission Support |
| Main assessment | FAB for recent entry-level FAM hiring | Vacancy-specific evaluation |
| Travel | Constant or extensive for operational FAM work | Vacancy dependent |
| In-flight duties | Core possible assignment | Not the defining function |
| Firearms | Required for FAM appointment | Depends on the investigator position |
| PAT | Required in recent entry-level FAM recruitment | Vacancy dependent |
| Polygraph | Required in recent entry-level FAM recruitment | Vacancy dependent |
| Clearance | Recent FAM recruitment required Top Secret | Depends on the investigator vacancy |
| Main work product | Operational law-enforcement action and mission execution | Evidence, interviews, investigative findings and case reports |
Do not assume every TSA Criminal Investigator vacancy uses the FAM age limit, FAB, PAT or training sequence. Read the specific announcement.
Investigators, Inspectors and Intelligence Specialists Are Different
Several TSA titles can sound interchangeable but are not.
Criminal Investigator
Develops criminal or administrative cases and may work under federal criminal-investigation authorities defined by the vacancy.
Transportation Security Inspector
Evaluates compliance with transportation-security regulations, security directives and approved programs. A TSI is not automatically an armed criminal investigator.
Intelligence Operations Specialist
Collects, evaluates, interprets and disseminates information affecting national and transportation security. Intelligence work can support law enforcement without conferring arrest authority.
Federal Air Marshal
Performs armed operational law enforcement in the transportation domain, including air- and ground-based missions.
Applicants should match the actual duties and occupational series, not only the word “security,” “investigator” or “specialist.”
Pay, LEAP and Retirement
Federal Air Marshal compensation uses TSA’s SV pay-band system and applicable locality treatment. Qualifying FAM positions can receive Law Enforcement Availability Pay after the conditions stated in the announcement are met.
Recent entry-level FAM recruitment described LEAP as compensation for substantial unscheduled duty and did not authorize it until completion of initial training and receipt of FAM badge and credentials.
Qualifying FAM appointments can receive primary federal law-enforcement retirement coverage. This can involve enhanced accrual, earlier retirement eligibility, mandatory-separation rules and additional employee contributions.
Criminal Investigator compensation, LEAP eligibility and retirement coverage depend on the exact position. Series 1811 alone should not be used to assume every TSA investigator vacancy has identical pay or covered-service treatment.
See the TSA pay-scale guide and TSA retirement-benefits guide.
Resume and Application Strategy
Law-enforcement and investigation applications require more evidence than a list of job titles.
For Federal Air Marshal entry-level applications
Follow the current page limit and required fields. Recent federal resume rules and TSA announcements have required concise resumes showing duties, accomplishments, dates, work schedule, hours and federal grade or band when applicable.
For supervisory FAM and AFSD-LE roles
Show:
- law-enforcement authority exercised;
- missions or programs led;
- personnel supervised;
- interagency coordination;
- high-risk decisions;
- policy implementation;
- operational results;
- employee development; and
- responsibility for protected information.
For Criminal Investigator roles
Show:
- investigations planned and completed;
- statutes, regulations or policies applied;
- interviews conducted;
- evidence collected and evaluated;
- reports, affidavits or case files prepared;
- coordination with counsel or prosecutors;
- findings supported by evidence; and
- outcomes without disclosing protected case information.
Never copy the announcement word for word or include classified, investigative-sensitive or operationally protected details.
Career Fit
Federal Air Marshal work may fit someone who accepts:
- carrying and potentially using a firearm;
- extensive domestic and international travel;
- irregular and extended duty;
- physical and medical standards;
- a law-enforcement polygraph;
- Top Secret vetting;
- operational secrecy;
- geographic mobility; and
- high-consequence decisions with limited immediate backup.
Criminal-investigation work may fit someone who prefers:
- evidence development;
- detailed interviews;
- records analysis;
- legal and procedural accuracy;
- long-form reports;
- case planning; and
- work that can continue for months rather than one immediate operational event.
Neither path should be chosen only for the title, badge, travel or retirement system.
Common Mistakes
Candidates often:
- confuse TSO and FAM hiring;
- assume every TSA investigator is part of LE/FAMS;
- assume Criminal Investigator and Transportation Security Inspector are the same occupation;
- purchase TSO preparation for the FAB;
- ignore the FAM age condition through entry on duty;
- fail to document veteran preference or prior covered service;
- underestimate PAT and medical requirements;
- ignore firearms restrictions;
- conceal drug, criminal or financial history;
- attempt polygraph countermeasures;
- treat a FAB pass as a job offer;
- expect immediate selection for VIPR, JTTF or a preferred field office;
- assume AFSD-LE or SAC is an entry-level position;
- reuse one generic resume for operational and investigative vacancies;
- disclose Sensitive Security Information or case-sensitive information; or
- resign before receiving a final written offer.
Frequently Asked Questions
What is TSA’s main operational law-enforcement position?
Federal Air Marshal.
Are Transportation Security Officers law-enforcement officers?
No. TSOs perform passenger and property screening. They do not automatically hold Federal Air Marshal law-enforcement authority.
Is TSA Criminal Investigator part of LE/FAMS?
TSA’s current public careers page lists Criminal Investigator under Mission Support rather than the LE/FAMS career category. The specific vacancy determines the organization, authorities and hiring conditions.
Is a Criminal Investigator the same as a Transportation Security Inspector?
No. Criminal Investigators develop criminal or administrative cases. Transportation Security Inspectors primarily conduct regulatory compliance and security-program oversight.
Is a polygraph required for Federal Air Marshal hiring?
Recent entry-level recruitment required a favorable law-enforcement pre-employment polygraph result, and TSA’s current federal hiring page lists a polygraph examination under Law Enforcement requirements.
What clearance do Federal Air Marshals need?
Recent entry-level FAM recruitment and recent AFSD-LE vacancies required Top Secret eligibility. The active announcement controls.
Can a TSO become a Federal Air Marshal?
A TSO can apply when eligible and qualified but must complete the full FAM application and selection process.
Can a new FAM choose VIPR or JTTF immediately?
Not as a guaranteed condition. Assignments depend on organizational needs, qualifications, performance, vacancies and selection.
Is AFSD-Law Enforcement the same as AFSD-Screening?
No. AFSD-LE coordinates law-enforcement liaison and reports through the LE/FAMS chain for personnel and law-enforcement matters. AFSD-Screening manages screening programs within the airport-security organization.
Is SAC an executive position?
Yes. TSA lists Supervisory Air Marshal in Charge among its TSES executive roles.
Do all TSA 1811 positions receive the same LEAP and retirement coverage?
Do not assume so. Pay, LEAP and covered retirement depend on the actual position, authority, service history and announcement.
