A person cannot become a prosecutor without passing through at least two separate screening processes, and often three. The first happens before the person is even licensed to practice law. The second happens when a district attorney’s office, state attorney general, or United States Attorney’s office actually hires the person into a prosecutor role. A third layer, a public trust or national security suitability review, applies to many federal prosecutors. Each stage is run by a different authority, asks different questions, and is governed by different rules. None of them work quite like the employment background check most private employers run through a consumer reporting agency.
Every prosecutor starts as a licensed attorney
Before a candidate can prosecute a single case, the state’s bar admission authority has to certify that the person has the “character and fitness” to practice law at all. This review is separate from the bar exam itself and is run by each state’s supreme court or its board of bar examiners, not by the hiring office. Applicants typically disclose criminal history, academic discipline, financial history including unpaid debts and bankruptcy, prior bar denials in other states, and any history of candor problems with a court or licensing body. The State Bar of California describes its moral character determination as an assessment of “honesty, trustworthiness, diligence, and reliability” that every applicant for admission must satisfy, and the process can include a formal investigation before a license is issued, according to the State Bar of California’s Moral Character Determination page. A prior arrest or conviction does not automatically bar admission. Boards generally weigh the nature of the conduct, how long ago it happened, and evidence of rehabilitation, and the specific standard and process vary by state.
A fuller look at how this review works, including what disclosures bar examiners require and how prior conduct is weighed, is covered in our post on attorney character and fitness background checks.
What a state or local district attorney’s office screens for
Passing the bar makes someone eligible to practice law, not eligible to prosecute. A district attorney, state’s attorney, or county prosecutor’s office runs its own hiring screen on top of bar admission, and because these offices are state and local government employers, the details of that screen are set by state law, county personnel rules, and each office’s own policy rather than by a single national standard. Common elements include a fingerprint based state and FBI criminal history check, verification of bar license status and any pending disciplinary matters, reference and prior employment checks, a credit check for offices that handle financial crimes or have cash handling duties, and a drug screening consistent with the jurisdiction’s public employment rules. Many prosecutor roles also carry access to law enforcement databases and sealed case files, which is one reason these offices tend to run a more detailed check than a typical private sector hire.
Because this layer sits entirely within state and local government, candidates should expect meaningful variation from one office to another. Some counties require a polygraph for entry level prosecutors who will also handle law enforcement liaison duties, similar to what many police departments require of sworn officers; others do not use a polygraph at all. Where a particular office has no published rule on a given topic, the honest answer is that the requirement simply varies, not that every office follows the same checklist.
Assistant United States Attorneys and the federal suitability process
Prosecutors who work for a United States Attorney’s office, as Assistant United States Attorneys, are federal employees, and federal civil service hiring runs through its own suitability framework rather than a private background check product. The Department of Justice’s Office of Adjudication, Recruitment, and Management reviews the suitability of every attorney who is offered a position at the Department. That review is based on the applicant’s completed security forms, fingerprint and credit checks, a full field FBI background investigation, and tax and bar checks specific to attorney applicants. The investigation looks back seven to ten years depending on the position, and OARM weighs factors including tax filing and payment history, credit history, candor, and any history of controlled substance use, according to the Department of Justice’s own Suitability and Background Investigation page.
That attorney specific process sits inside the broader federal suitability system that OPM administers for the entire executive branch. Under that system, OPM’s Suitability Executive Agent program sets policy, adjudicates certain cases, and provides oversight so that suitability and fitness decisions are applied consistently across federal agencies, as described on the U.S. Office of Personnel Management’s Suitability page. Federal regulation requires agencies to designate which of their positions are public trust positions and to set the investigative requirements that apply to each designation, a rule found at 5 CFR Part 731, Suitability. Most Assistant United States Attorney positions are designated public trust because of the access prosecutors have to sensitive case information, grand jury material, and law enforcement systems, which triggers the fuller investigation described above rather than the lighter review used for many other federal jobs.
Public trust review is not the same thing as a security clearance
These two terms get used interchangeably in casual conversation, but they are legally distinct. A public trust designation is about whether a person can be trusted with sensitive but unclassified information and authority, and it is adjudicated under the suitability rules described above. A security clearance is about access to classified national security information and is adjudicated under a separate framework. Some federal prosecutors, particularly those who prosecute national security, espionage, or export control cases, may also need an actual security clearance in addition to the standard public trust suitability review that applies to attorney hiring generally. Our post on how a security clearance compares to an employment background check walks through how the two processes differ in scope, authority, and what each one actually verifies.
How the stages compare
| Screening stage | Who conducts it | What it typically covers | Primary authority |
|---|---|---|---|
| Bar admission character and fitness | State supreme court or board of bar examiners | Criminal history, financial history, academic conduct, candor with prior courts and licensing bodies | Each state’s bar admission rules |
| State or county prosecutor hiring | District attorney’s office or county personnel department | Fingerprint based criminal history, bar standing, references, drug screening, sometimes credit history | State and local law, office policy |
| Federal prosecutor (Assistant U.S. Attorney) | DOJ Office of Adjudication, Recruitment, and Management | Full field FBI investigation, fingerprint and credit checks, tax and bar checks, suitability factors | 5 CFR Part 731, DOJ OARM policy |
| Public trust or clearance designation | OPM policy, agency suitability and security officials | Position risk and sensitivity level tied to the required investigation depth | OPM Suitability Executive Agent, 5 CFR 731.106 |
Where this intersects with the Fair Credit Reporting Act
Government agencies that run their own hiring investigations in house, using their own staff and federal or state records authority rather than a third party consumer reporting agency, generally are not acting as users of a consumer report under the Fair Credit Reporting Act for that investigation. That is different from a private law firm, legal staffing agency, or nonprofit legal aid office that orders a background report on a candidate through a consumer reporting agency. In that situation the employer still has standard FCRA duties, including a standalone disclosure, the candidate’s written authorization, and pre adverse and adverse action notices with a copy of the report and a summary of rights before the employer may act on anything in the report. State law and the typical seven year reporting window for older criminal records can also affect what shows up, and the rule is not identical in every state, so the primary source for a given jurisdiction should always be checked rather than assumed.
Frequently asked questions
Does a prosecutor need to pass a background check before or after passing the bar exam?
Character and fitness review happens alongside or before bar admission and is separate from the hiring background check that a district attorney’s office or United States Attorney’s office runs later. A candidate can be a licensed attorney and still fail a later hiring investigation, and the two processes do not share a single file.
What shows up in a district attorney’s office background check?
Typical elements include a fingerprint based criminal history search, verification of bar license standing, reference and employment checks, and drug screening, with credit checks used by some offices. Exact requirements vary by state and by county, so a specific office’s own hiring policy is the authoritative source.
Do federal prosecutors need a security clearance?
Most Assistant United States Attorney positions are designated public trust positions and go through the Department of Justice’s suitability and background investigation process rather than a classified security clearance. Prosecutors assigned to national security or similar sensitive matters may also need an actual clearance in addition to that process.
Can a past arrest or conviction keep someone from becoming a prosecutor?
It can be a factor at both the bar admission stage and the hiring stage, but it does not automatically disqualify a candidate. Bar authorities and hiring offices generally weigh the nature of the conduct, how long ago it occurred, and evidence of rehabilitation rather than applying an automatic bar.
Is a prosecutor background check the same as a typical employer background check?
No. Bar character and fitness review and federal suitability investigations are run directly by government authorities under their own rules, not by a consumer reporting agency under the Fair Credit Reporting Act. A private legal employer that orders a report through a consumer reporting agency still has to follow standard FCRA notice and authorization steps.
