Joining the military is not a simple paperwork exercise. Before anyone raises their hand and takes the oath of enlistment, the Department of Defense runs them through a layered screening process that looks at age, citizenship, education, medical history, drug and alcohol history, and, central to this article, criminal history and moral character. Applicants who do not meet every standard are not enlisted, appointed, or inducted unless they qualify for a waiver, and some offenses cannot be waived at all.
This screening is governed by a federal regulation, not a commercial consumer report, so it does not work the way a civilian employment background check does. Recruits do not receive a Fair Credit Reporting Act disclosure or an adverse action notice. Instead, the process runs through the Military Entrance Processing Station (MEPS) system and, for jobs that require access to classified information, through a separate federal personnel vetting system. Here is what actually gets reviewed, in the order most applicants experience it.
The moral character and criminal history review
The Department of Defense’s enlistment standards are codified in 32 CFR Part 66, Qualification Standards for Enlistment, Appointment, and Induction. Under that regulation, the stated purpose of the character and conduct standards is to minimize the entrance of people who are likely to become disciplinary cases, security risks, or a disruption to good order and discipline. The services are explicit that they are not meant to serve as a rehabilitation program for people who have not already met the legal and moral standards expected of the public at large.
As a baseline, an applicant is considered ineligible if any of the following apply, under 32 CFR 66.6(b)(8):
- The applicant is currently under judicial restraint, including bond, probation, imprisonment, or parole.
- The applicant has a significant criminal record. A felony conviction is a statutory bar to enlistment, though a waiver may be requested in a meritorious case.
- The applicant has a felony conviction, or a juvenile adjudication, for rape, sexual abuse, sexual assault, incest, another sexual offense, or any offense that requires sex offender registration. These cases are permanently barred. No waiver is available.
- The applicant was previously separated from a branch of service under conditions other than honorable, or for the good of the service.
- The applicant has shown a pattern of antisocial behavior or other traits of character that would make them unfit for service.
- The applicant receives an unfavorable finding from the DoD Consolidated Adjudication Facility on the background investigation described below.
Recruiters and MEPS staff gather this history from the applicant’s own disclosures, court and police records, and the fingerprint based check described further down. Juvenile records, dismissed charges, and diversion outcomes can still count as an “adverse adjudication” under the regulation’s definitions, even when the case did not end in a conviction, so applicants are generally expected to disclose more than they might assume is relevant.
Waivers: who can apply and who cannot
32 CFR 66.7 lays out the waiver categories: medical, dependency, and conduct. A conduct waiver requires the service to collect the who, what, when, where, and why of the offense, plus letters of recommendation from community figures such as school officials, clergy, or law enforcement, speaking to the applicant’s character. The regulation is direct about the fact that a waiver is a discretionary decision made case by case, not an automatic path back to eligibility; the Secretary of the Military Department concerned makes the final call.
Waivers are generally structured around how the offense is classified, for example a single “major misconduct” offense, two “misconduct” offenses, or a pattern that includes several lesser offenses. None of that process is available for the sex offense category above. The regulation states plainly that enlistment, appointment, or induction is prohibited in those cases and that no waiver exists, regardless of the applicant’s other qualifications.
The questionnaire and the fingerprint check
Every applicant completes an enlistment questionnaire that asks directly about arrests, charges, convictions, and prior military separations. That questionnaire is not the end of the review. Under 32 CFR 66.6(b)(8)(vi), accession is tied to the results of a National Agency Check with Law and Credit, commonly called a NACLC, or a higher level investigation, adjudicated against the national security standards originally set out in Executive Order 12968. A service member can be accessed, including being shipped to training, once that investigation has been submitted to and accepted by the federal investigative service provider and an advanced fingerprint check has returned no disqualifying information. If the full adjudication is not finished until after accession, any disqualifying information that later surfaces is referred to the appropriate personnel office for action.
In practical terms, this means the fingerprint and records check is not a courtesy step. It is the mechanism that confirms the applicant’s own disclosures against government records before training begins.
Security clearance investigations for cleared jobs
A separate and more involved layer applies to recruits headed into jobs that require access to classified information, which covers a large share of military occupational specialties. Executive Order 12968 established the government wide framework for eligibility determinations, and Executive Order 13467 later reorganized how the federal government handles suitability, contractor fitness, and security clearance vetting as a single integrated process rather than three separate ones.
The substantive standards an adjudicator applies once the investigation is complete are published at 32 CFR Part 147, Adjudicative Guidelines for Determining Eligibility for Access to Classified Information. That regulation describes a “whole person” review: an examination of a sufficient period of a person’s life, weighing favorable and unfavorable information together, rather than an automatic disqualification for any single negative item. The guidelines cover areas such as criminal conduct, financial considerations, foreign influence, personal conduct, and substance abuse, and they apply to military and civilian personnel alike.
The paperwork that starts this process is the Questionnaire for National Security Positions, Standard Form 86 (SF-86), which collects residence history, employment history, foreign contacts, financial history, and more. Completing the SF-86 begins the investigation; it does not by itself grant or deny eligibility.
Accession review versus clearance investigation
| Feature | Accession background review | Security clearance investigation |
|---|---|---|
| Applies to | Every applicant for enlistment, appointment, or induction | Applicants assigned to a position requiring access to classified information |
| Governing rule | 32 CFR Part 66 | 32 CFR Part 147, Executive Order 12968, Executive Order 13467 |
| What starts it | Enlistment questionnaire, recruiter interview, fingerprint submission | SF-86 questionnaire |
| What it reviews | Age, citizenship, education, medical and drug history, criminal and moral character history | Whole person review including financial history, foreign contacts, personal conduct, and criminal history |
| Who decides | MEPS, the recruiting service, and the DoD Consolidated Adjudication Facility | The cognizant adjudication facility applying the adjudicative guidelines |
| Can a problem be waived | Yes, for most categories; no waiver for the sex offense bar | Adjudicated case by case under the whole person concept; not a simple waiver process |
Some applicants will only ever go through the first column. Anyone headed toward a cleared military occupational specialty goes through both, generally in that order, since accession standards are checked before someone enters service at all.
What this means for applicants and their families
None of this is designed to be a surprise. The questionnaire asks directly about the history that matters, and recruiters are expected to help applicants understand which category, if any, their background falls into. The most common mistake is not a disqualifying record itself but a failure to disclose it accurately, since an adjudicator weighing a disclosed issue against an undisclosed one treats the second far more seriously. Applicants with a prior arrest, even one that did not result in a conviction, or a juvenile record, should raise it with their recruiter rather than assume it will not surface during the records and fingerprint check.
For readers coming from the hiring side rather than the enlistment side, this process is also a useful point of comparison. A government accession review and a civilian pre-employment background check serve similar goals, screening for risk before someone is given responsibility or access, but they run on entirely different legal authority and timelines.

Frequently asked questions
Does the military run a background check before enlistment?
Yes. Every applicant goes through a review of criminal history, moral character, and prior military service outcomes under 32 CFR Part 66, along with a fingerprint based records check tied to the accession process.
Can someone enlist with a felony conviction?
A felony conviction is a statutory bar to enlistment, but 10 U.S.C. 504, referenced in 32 CFR Part 66, allows the service concerned to grant a waiver in a meritorious case. Approval is decided individually and is not automatic.
Is a waiver available for every type of offense?
No. A felony conviction or juvenile adjudication for rape, sexual abuse, sexual assault, incest, another sexual offense, or any offense requiring sex offender registration permanently bars enlistment, appointment, or induction, with no waiver available.
Does every recruit go through a security clearance investigation?
No. Every recruit goes through the accession background review. A full security clearance investigation under 32 CFR Part 147 applies specifically to recruits assigned to positions that require access to classified information.
What form starts the security clearance process?
The Questionnaire for National Security Positions, Standard Form 86 (SF-86), starts the investigation. Completing it does not by itself determine eligibility.
What happens if an applicant does not disclose a past arrest?
Adjudicators generally treat an undisclosed issue more seriously than the same issue disclosed up front, since the fingerprint and records check is designed to compare the applicant’s own statements against official records.
This article is general information only, based on published federal regulations, and is not legal advice. Enlistment eligibility depends on individual facts and current service specific policy, so applicants should confirm their situation with a recruiter or qualified counsel.
