The 6 Categories of Evidence That Win VA Claims

The VA does not grant claims because a veteran deserves it — it grants claims that are proven. And proof comes from evidence. Almost every strong claim is built from the same six categories. Know them, and you can see at a glance what your claim has and what it is missing.

The 6 categories

  • 1. Diagnosis evidence. A current, documented diagnosis from a qualified provider. Without a present diagnosis, there is nothing to rate.
  • 2. Service-connection evidence. Records that tie the condition to your service — service treatment records, personnel files, deployment and exposure records.
  • 3. Nexus opinion. A licensed provider’s opinion that your condition is “at least as likely as not” related to service. This is the bridge between categories 1 and 2 — and the most common missing piece.
  • 4. Severity evidence. How often, how intense, and how disabling the condition is. Severity sets your rating percentage, and it is the most under-documented category by far.
  • 5. Lay (personal) statement. Your own first-hand account of what happened and how it affects you.
  • 6. Buddy statements. Corroboration from people who witnessed the event or see your symptoms — fellow service members, family, coworkers.

Where claims usually fall short

Most veterans nail categories 1, 2, and 5 but come up short on 3 (nexus) and 4 (severity). If you only fix two things, make them a solid nexus and complete severity documentation — that is where ratings are won or lost.
