What Is the DHS Suitability Determination Process?

The DHS suitability determination process is a background-based review, governed by 5 CFR Part 731, that decides whether your character and past conduct make you fit to work for or alongside the Department of Homeland Security.¹ Adjudicators weigh your investigative file against nine specific factors before issuing a favorable or unfavorable decision. A favorable determination lets you move forward with the job; an unfavorable one can withdraw the offer, remove you from a position, or bar you from federal employment for up to three years.

Who the Process Applies To

Anyone who needs access to DHS facilities or information systems goes through some version of this review. That includes federal employees, contractors, interns, and volunteers. For federal applicants and appointees, DHS calls it a “suitability determination.” For contractor employees, the same evaluation is called a “fitness determination,” but the substance is functionally similar.²

One boundary worth naming up front: suitability is not the same as a security clearance. A clearance decides whether you can access classified information. Suitability decides whether you belong in federal service at all. You can pass one and fail the other. Financial problems and foreign contacts, which weigh heavily in clearance adjudication, are not on the suitability list. If your position requires both, the two reviews happen in parallel under different rules.

What Forms You’ll Complete and How Deep the Investigation Goes

Position risk drives the paperwork and the depth of the check. DHS designates positions as low, moderate, or high risk based on the potential harm someone in the role could cause.²

Low risk (Tier 1): SF-85. Basic identity verification, criminal records, and employment history.
Moderate risk (Tier 2): SF-85P. Adds credit checks and more detailed interviews.
High risk (Tier 4): SF-85P again, but with substantially broader record checks and deeper personal history review.

Positions that also require access to classified information use the SF-86 and are investigated at Tier 3 or Tier 5.³ Those investigations feed a security clearance decision, though a suitability determination still runs alongside.

The Nine Suitability Factors

Adjudicators can only find you unsuitable based on the nine factors listed in 5 CFR 731.202. Agencies making fitness determinations for contractors must consider these same nine at minimum, and may add job-related criteria.⁴

Misconduct or negligence in employment.
Criminal conduct, whether or not it produced a conviction.
False statements or fraud in the application. Only OPM, not individual agencies, can take suitability action on this factor.
Dishonest conduct beyond application fraud.
Excessive alcohol use at a level that would interfere with the job or endanger others, absent evidence you’ve addressed it.
Illegal drug use without evidence of rehabilitation.
Knowingly participating in acts to overthrow the U.S. Government by force. Only OPM can act on this factor.
A statutory or regulatory bar that makes placing you in the position unlawful.
Violent conduct, whether or not charges followed.

How Adjudicators Weigh What They Find

Finding one of the nine factors in your background does not automatically make you unsuitable. Adjudicators apply seven additional considerations before deciding:⁴

Nature of the position. A DUI matters more for a driving role than a desk role.
Seriousness of the conduct.
Circumstances at the time.
Recency. Older conduct carries less weight.
Your age when it happened.
Contributing societal conditions.
Evidence of rehabilitation, such as completed treatment or a stable work record since.

This is often called the whole-person concept. A single negative event does not necessarily end your candidacy if you can show it is behind you.

Marijuana Use

Marijuana remains a Schedule I controlled substance under federal law regardless of state law, and federal employees are expected to abstain. But OPM guidance directs agencies not to automatically disqualify someone based on past use alone.⁵ Recency, circumstances, and evidence of rehabilitation all apply, and a credible commitment to stop using can count in your favor even if the last use was fairly recent. The practical rule: do not lie about past use on your forms, and be prepared to show you’ve stopped.

What the Sequence Looks Like

The process begins after you receive a conditional job offer. You’ll complete the appropriate form (SF-85, SF-85P, or SF-86) electronically through the e-QIP system. These forms ask about residences, employment, education, criminal history, foreign contacts, and other personal history. Accuracy matters enormously here: intentional false statements are one of the nine factors and one of the most common reasons for unfavorable outcomes.

The Defense Counterintelligence and Security Agency (DCSA) typically conducts the background investigation. Investigators may check criminal databases, financial records, and court records, and they routinely interview references, former employers, and neighbors. They may interview you as well.³ If DCSA reaches out, cooperate fully. Failing to respond can cause your investigation to be cancelled.

DCSA sends the completed investigation to DHS for adjudication. An adjudicator reviews the file against the nine factors and the seven additional considerations, then issues a determination. Timing varies with tier and case complexity. Lower-tier suitability investigations generally move faster than clearance-level ones, though backlogs can cause delays.

What an Unfavorable Determination Can Do

Most investigations end in a favorable determination and you move forward with the job. If yours doesn’t, the consequences depend on where you are in the process. Under 5 CFR 731.203, possible suitability actions include:⁶

Cancellation of eligibility, removing your name from the list of eligible candidates.
Removal from federal service if you’re already in the position.
Cancellation of reinstatement eligibility obtained through fraud.
Debarment from competing for federal positions for a set period.

For applicants who haven’t started yet, an unfavorable finding usually means the conditional job offer is withdrawn.

Debarment

OPM can bar you from competing for any position in the competitive service or career Senior Executive Service for up to three years from the date of the unfavorable determination.⁷ An individual agency can also impose its own debarment for up to three years within that agency. Duration is at OPM’s discretion, with no fixed formula. OPM can also impose an additional debarment after the first expires, or if new disqualifying conduct surfaces during the existing bar.

Once a debarment ends, eligibility does not come back automatically. You have to reapply and go through the full 5 CFR 731 process again.⁸ Debarment is reserved for more serious cases, not every unfavorable determination.

How to Respond and Appeal

Before OPM or an agency finalizes an unfavorable suitability action, you must receive written notice of the proposed action, the specific charges, and access to the materials the agency relied on. That notice must arrive at least 30 days before the proposed action takes effect, giving you a window to respond in writing.⁹ Your written response is your best chance to present evidence of rehabilitation, explain circumstances, or correct factual errors. Many cases are resolved at this stage, so treat it seriously.

The appeal path beyond that response is currently in flux. Historically, individuals who received a final unfavorable action could appeal to the Merit Systems Protection Board, with further review available in the U.S. Court of Appeals for the Federal Circuit. In early 2026, OPM published a proposed rule that would remove MSPB jurisdiction over suitability appeals and return that authority to OPM.¹⁰ The comment period closed in March 2026, and the rule has not been finalized. Until a final rule takes effect the existing framework remains in place, but verify the current process at the time you receive any notice.

Moving From Another Federal Agency

If you’ve already passed a suitability investigation at another federal agency, DHS may not start from scratch. Federal regulations require agencies to accept a prior background investigation when you transfer, get reassigned, or move between agencies without a break in service, as long as the new position isn’t at a higher risk level than the one you were investigated for.¹¹

Reciprocity can still apply with a break in service if the break falls within supplemental guidance limits and the prior investigation met or exceeded the level required for the new position. Two exceptions trigger a fresh adjudication: the existing investigative record contains conduct that conflicts with the core duties of the new position, or the agency has prescribed additional fitness factors that weren’t addressed originally. In practice, a same-tier move between agencies runs noticeably smoother than a first-time application.

Continuous Vetting After You’re Cleared

A favorable determination doesn’t freeze your record at the point of hire. Under the government-wide Trusted Workforce 2.0 initiative, periodic reinvestigations every five or ten years are being replaced with continuous vetting, meaning automated record checks that run throughout your employment.¹² These checks pull from criminal, terrorism, financial, credit, foreign travel, and public records databases. Employees and contractors can also self-report security-relevant information such as foreign travel through an online portal. Full federal workforce enrollment is expected by September 2028.¹³

The practical effect: a new arrest, a sudden financial crisis, or unreported foreign contacts can trigger a review at any time. If a flag appears, the agency evaluates it against the same nine factors and the same additional considerations that governed your initial determination.
