The Individual Longitudinal Exposure Record (ILER) is the joint DoD/VA record of where you served and what you were exposed to. VA raters pull it to corroborate and concede toxic exposure— which, for a PACT Act presumptive, can be the whole ballgame: qualifying service on your ILER means you don't have to prove exposure yourself. You already have one (it's auto-populated). This guide explains what's in it, how to get your copy, how to read it, and how to turn it into claim evidence — including what to do when it's incomplete.
The Individual Longitudinal Exposure Record is a joint Department of Defense and Department of Veterans Affairs system that pulls together, in one place, where you served and the occupational and environmental hazards you were potentially exposed to across your entire career. It is built from authoritative DoD personnel and deployment data, so you do not sign up for it — if you have military service records, you have an ILER.
Its purpose is adjudication. When you file a disability claim that involves toxic exposure, the VA claims processor reviews your ILER to confirm your qualifying service and exposures. A 2024 Government Accountability Office review (GAO-24-106423) examined how DoD and VA staff use these military toxic-exposure records in exactly this way.
Bottom line: the ILER is the VA's own evidence about your exposure history. Knowing what it says — and getting ahead of its gaps — is one of the highest-leverage things you can do before filing an exposure claim.
Under the PACT Act (Pub. L. 117-168) and 38 U.S.C. § 1119, veterans who served in qualifying locations during qualifying periods get conceded exposure — the VA accepts that the toxic exposure happened, with no need for you to prove it. Your ILER is how the rater confirms that qualifying service.
For claims that are not presumptive — a direct-service-connection exposure claim, or a secondary condition linked to an exposure — the ILER is objective, government-generated evidence placing you with a specific hazard. That supports the “in-service event” element of service connection and strengthens any nexus opinion.
Here is the path the ILER unlocks — from boots on the ground to a presumptive grant:
An ILER is organized around your service timeline. Expect two kinds of information:
A chronological record of your deployments and duty locations with start and end dates. This is what the VA matches against the PACT Act's qualifying locations and time windows.
Potential exposures associated with your locations and occupation. Common categories:
When you read your ILER, do two things: (1) confirm every deployment and location is present with correct dates, and (2) cross-check each location against the presumptive framework — our Deployment Locations reference lists 855 sites with their known exposures, and the PACT Eligibility Scanner maps a location to the conditions it presumptively covers.
The ILER was designed as an internal tool for VA claims processors and DoD/VA clinicians, so for most veterans it is not yet a one-click download. The reliable routes today:
1. Through the VA or your VSO. Ask your VA provider/clinician or your accredited Veterans Service Officer to query and print your ILER exposure summary. They have the access the public portal is still rolling out.
2. Automatically, during your claim. When you file an exposure-related claim, the rater reviews your ILER as a matter of course — you do not have to attach it.
3. Direct veteran access (expanding). The VA is directed to provide veterans read-only, printable access to their ILER, with secure sign-in (CAC/PIV, Login.gov, ID.me). Availability is being expanded — check VA Public Health (“Individual Longitudinal Exposure Record”) for the current portal status.

Match locations to presumptives. For each location on your ILER, check whether it triggers conceded exposure and which conditions are presumptive — start with the PACT Scanner and Deployment Locations.
Cite it in your statement. Reference the specific deployment and exposure shown in your ILER in your personal statement so the rater connects record to claim.
Refile denials. If a pre-PACT exposure claim was denied, the ILER plus the PACT Act can be new and relevant evidence for a Supplemental Claim — with effective-date protection under 38 C.F.R. § 3.114.
ILER coverage is strongest for recent, standard deployments and can be thin for older service, TDY/short tours, or unusual assignments. Never let an incomplete ILER sink a valid claim. Build the record yourself with:
Your DD-214, orders, performance evaluations, and unit/command records showing the location and dates.
The VA/DoD Airborne Hazards and Open Burn Pit Registry, if you served near burn pits.
Buddy letters and your own lay statement describing the exposure and timeframe.
Then ask the VA to correct the record so future claims start from accurate data.
Educational information only — not legal, medical, or VA advice. Claim Recon is not the VA, a law firm, or an accredited representative. VSO representation is free by law (38 C.F.R. § 14.628).
The Individual Longitudinal Exposure Record (ILER) is a joint Department of Defense and Department of Veterans Affairs system that consolidates a service member’s deployment locations and known occupational and environmental exposures into a single lifetime record. VA claims processors use it to corroborate (and often concede) toxic exposure when adjudicating disability claims.
You do not register. The ILER is automatically populated from authoritative DoD personnel and deployment data, so virtually every veteran and service member with military records already has an ILER entry.
The ILER was built as an internal tool for VA claims processors and DoD/VA clinicians, so it is not yet a simple self-service download for most veterans. The reliable routes today: (1) ask your VA provider/clinician or your accredited VSO to query and print your ILER exposure summary; (2) it is reviewed automatically by the VA rater when you file an exposure-related claim. The VA is directed to provide veterans read-only, printable ILER access, with secure sign-in (CAC/PIV, Login.gov, ID.me) rolling out.
For PACT Act presumptive claims, if your ILER shows qualifying service in a covered location during the covered period, the VA concedes toxic exposure — you do not have to prove it yourself. For direct or secondary exposure claims, the ILER is objective evidence linking you to a specific hazard, which strengthens a nexus.
ILER data can be incomplete, especially for older or non-standard service. Do not rely on it alone — supplement with your DD-214, orders, unit records, the VA/DoD Airborne Hazards and Open Burn Pit Registry, and buddy/lay statements, and ask the VA to correct the record.
No. The Toxic Exposure Screening (TES) is a short health screening offered at VA health-care visits; the ILER is the underlying exposure record. They are complementary — the screening flags concerns, the ILER documents the exposure history.
