You ran investigations in uniform. Maybe you ran background investigations. Maybe you worked suitability inquiries. Maybe you handled compliance and fraud cases that ended in administrative action, not criminal prosecution. Now you are staring at USAJOBS, and you keep seeing one code: GS-1810.

That code may be your lane. The GS-1810 General Investigating Series covers non-criminal federal investigative work. Think background checks, security clearance reviews, program integrity cases, and compliance reviews. The results lead to administrative judgments, not criminal prosecution. If your work in uniform involved criminal violations and arrest authority, look at GS-1811 too. That is the criminal investigator series, and it may fit you better. We cover the difference below.

The problem with 1810 is the resume. Your military case work was real. But the federal application reads your experience against a fixed standard. Miss that standard, and your resume sinks to the bottom of the pile. It does not get rejected by a robot. It just never gets read by the human who picks from the list.

Here is what the 1810 series actually is. Where it gets used. What each grade demands. And how to write bullets that prove you qualify. No fluff. Just the standard and how your record meets it.

What Is the GS-1810 General Investigating Series?

GS-1810 is a federal job series. The Office of Personnel Management sets it. It covers work that investigates, examines, and gathers facts. The goal is to enforce a law, a rule, or a federal program requirement. One key limit defines the series. GS-1810 does not cover criminal investigations. The results lead to administrative action, not criminal prosecution.

Think of it as the administrative fact-finding lane. An 1810 investigator interviews people. They review records. They build a case file. They write reports that hold up under review. Sound familiar? It should. It looks a lot like the non-criminal case work you ran in uniform. If your military work was criminal investigation with arrest authority, that maps to GS-1811, not 1810.

The series sits inside OPM's 1800 group. That group covers inspection, investigation, enforcement, and compliance work. You can read the official OPM qualification standard for the 1810 series straight from the source. It is short. Read it once before you apply.

One thing trips veterans up. GS-1810 is not the same as GS-1811. The 1811 series is Criminal Investigator. That is the federal special agent role with arrest authority, a firearm, and 6(c) law enforcement retirement. The 1810 series is the non-criminal lane. It covers administrative investigations like background checks and suitability inquiries. It does not cover criminal investigations. So the right code depends on the work you did in uniform. If you ran criminal cases with arrest authority, your primary target is 1811. If your work was administrative fact-finding, 1810 fits. Check the series on each announcement before you tailor.

Where Does the 1810 Series Get Used?

The 1810 series shows up across the federal government. It is not stuck in one agency. That is good news. More postings means more shots at a referral.

Agencies use 1810 investigators for work like background investigations, program fraud cases, security inquiries, and compliance reviews. Some of these jobs need a clearance. Many of them want someone who already knows how to run a clean investigation. That is you.

If you held a clearance in uniform, say so on your resume. A current or recent clearance is a real edge for 1810 work. It saves the agency time and money. Put your clearance level and date near the top.

What Are the Specialized Experience Requirements by Grade?

This is the part a lot of veterans get wrong. Each grade has its own bar. The bar is built on something called specialized experience. You have to prove it on paper. If you cannot, you do not qualify for that grade. It is that simple.

The 1810 series does not use its own special set of education rules. It runs on OPM's Group Coverage Qualification Standard for Administrative and Management Positions. So the grade ladder below comes from that standard. Here is how it breaks down.

What Is "Specialized Experience"?

OPM defines specialized experience as work that gave you the skills to do the job after a normal break-in period. It has to relate to the work of the position. And it has to be at a level equal to the next grade down.

Read that last part twice. To qualify for a GS-9, you need one year of experience equal to a GS-7. To qualify for a GS-11, you need one year equal to a GS-9. The grade you are targeting always points to the grade just below it. Your military case work counts. You just have to show it at the right level.

The Grade Ladder: GS-5 Through GS-12

Here is the standard, grade by grade. Note that the higher you go, the more education stops helping. At GS-12, it is all about specialized experience.

• GS-5: A 4-year college degree. Or three years of progressive experience, with one year equal to GS-4.
• GS-7: One full year of graduate study. Or Superior Academic Achievement at the bachelor's level. Or one year of specialized experience equal to GS-5.
• GS-9: A master's degree or two full years of graduate study. Or one year of specialized experience equal to GS-7.
• GS-11: A Ph.D. or three full years of graduate study. Or one year of specialized experience equal to GS-9.
• GS-12: One year of specialized experience equal to GS-11. Education does not substitute at this grade.

Most transitioning investigators land in the GS-7 to GS-11 band. A senior NCO with years of case work and a degree can be competitive for GS-9 or higher. A junior investigator may start at GS-5 or GS-7. Read the announcement. It will state the grade and the exact specialized experience it wants.

One rule to hold onto. The standard is a floor, not a guarantee. Meeting the bar gets you onto the eligible list. It does not promise a referral. The resume still has to read clean and hit the keywords. We cover that next. For the full picture on this, read how to prove you qualify on specialized experience.

How Does Military Investigative Experience Map to 1810?

This is where your record turns into a federal resume. Your job in uniform already did 1810 work. The titles are different. The work is not.

Look at what you actually did. You conducted interviews. You collected and preserved evidence. You wrote reports of investigation. You coordinated with legal. You testified or supported prosecution. Every one of those maps straight to 1810 duties.

If you came from a criminal investigation MOS, read this part with care. Army CID agents work the 31D CID Special Agent path. Air Force OSI runs through 7S0X1 Special Investigations. Marine investigators come from the 5821 Criminal Investigator field. Those are criminal investigator codes. Their primary federal target is GS-1811, the criminal investigator series, not 1810. If you also ran non-criminal administrative cases, like suitability or compliance work, that part of your record can support an 1810 application. But your criminal case work points to 1811. Each of those career pages breaks down the civilian translation in detail.

Not every 1810 candidate came from a pure investigations MOS. That is fine. The series pulls from a wider pool.

• Military police and security: An Army 31B Military Police or a Navy Master-at-Arms who ran investigations, took statements, and built case files has real 1810 experience.
• Intelligence backgrounds: S2 and G2 analysts who collected, vetted, and reported on sources do fact-finding work that lines up with parts of the 1810 role.
• Coast Guard investigators: The IV Investigator rate is a clean match for 1810 work.

The point is not your code. It is your case work. If you ran investigations, collected facts, and wrote reports that held up, you have a story to tell on the 1810 application.

How Do You Write 1810 Resume Bullets That Prove Specialized Experience?

A federal resume is not a private resume. It is longer and more detailed. You include hours per week, supervisor contact info, and a full account of your duties. But the length is now capped. As of September 27, 2025, USAJOBS enforces a hard two-page maximum. Go over, and the system blocks your submission. This is the enforced rule now, not just a best practice. So make every line earn its place.

Every bullet has one job. Prove specialized experience at the grade you want. Vague duty statements do not do that. Specific, measured accomplishments do.

Match the Announcement's Words

Read the specialized experience paragraph in the announcement. It lists the exact skills the agency wants. Those are your keywords. Use them in your bullets, in plain language, where they are true for you. The federal system, USA Staffing, scans for those terms. Miss them and your resume ranks low.

This is not keyword stuffing. It is mirroring the standard with real work you did. Our guide on how to find and use USAJOBS keywords shows the method.

Show the Level, Not Just the Task

Anyone can say "conducted investigations." That tells the rater nothing about your level. Show the scope. How many cases? How complex? Who did you brief? What was the outcome? Level is what separates a GS-7 bullet from a GS-11 bullet.

See the difference? The strong bullet names the volume, the case type, the actions, and the outcome. A rater can place that at a grade level fast. The weak one forces them to guess, and guesses break against you.

Spell Out Every Acronym

The rater may not know your military shorthand. Spell out CID, OSI, ROI, and any rating or MOS code the first time you use it. You can put the acronym in parentheses after. Do not make the person reading your resume translate it. That is your job, not theirs.

Claim Your Veterans Preference

Veterans preference can move you up the list. It applies to many 1810 jobs. You document it with your service record and any disability rating paperwork. The agency verifies it. If you qualify, do not leave it on the table. Start with the official USAJOBS page on veterans hiring paths to see how it works.

What Else Should You Know Before You Apply?

A few things save veterans a lot of pain on 1810 applications.

First, read the whole announcement. Not just the duties. The questionnaire and the specialized experience paragraph decide your fate. Many strong candidates self-rate too low on the questionnaire and screen themselves out. Answer honestly, but do not undersell real experience.

Second, apply to the right grade. If you barely meet a GS-11 bar, also apply to the GS-9 version if one is open. A lower grade in the door beats no offer at all. You can promote from inside.

Third, learn to read the posting like a map. Every announcement tells you what to write. If you know how to decode it, you can mirror it. Our guide on how to decode a USAJOBS job announcement breaks down each section.

And if you are still figuring out which federal series fit your background overall, our roundup of 10 federal job series every veteran should search is a good starting point. The 1810 series is one of several that reward military investigative and security work.

What to Do Next

You already did the hard part. You ran real investigations under pressure. The federal application is just translation. Your job now is to make a rater see your case work at the right grade, in their words, in two clean pages.

Pull up an 1810 announcement. Find the grade and the specialized experience paragraph. Then build your resume around it. Match the terms. Show the scope. Spell out the acronyms. Add the hours, dates, and supervisor. Claim your preference.

If you want the formatting handled for you, BMR's federal resume builder takes your military experience and shapes it into the federal format. It handles the hours, the structure, and the keyword mapping so you can focus on telling your story. Built by veterans who have sat on the hiring side of the federal process.

The 1810 series is wide open to people with your background. Most of your competition will submit a vague, too-short, civilian-style resume. Yours will prove the standard. That is how you get referred.
