What does "TDIU" stand for?

The term "TDIU" stands for "Total Disability based on Individual Unemployability." This designation is used in the context of veterans' benefits to acknowledge that a veteran is unable to secure or follow substantial gainful employment due to service-connected disabilities. It allows veterans who do not have a 100% disability rating to receive compensation at the 100% rate if their disabilities prevent them from working.

Understanding this concept is essential for service officers as it ensures that veterans receive the appropriate benefits they are entitled to based on their individual situations. Including "individual unemployability" emphasizes the personal assessment of a veteran's ability to work, which is crucial in their evaluation for benefits.

The other options, while they may sound relevant, do not accurately reflect the established terminology or framework used by the Department of Veterans Affairs in relation to disability compensation. Thus, "Total Disability based on Individual Unemployability" is the correct definition of TDIU.
