The three types of line of duty determinations are informal, formal, and

• A. Administrative
• B. Associative
• C. Disease/injury
• D. General

Answer: (A)

Line of Duty determinations are handled through three review pathways that reflect how formal or informal the process is. Informal determinations are quick, supervisor-level assessments used for straightforward or minor injuries or illnesses that clearly happened in the line of duty. Formal determinations involve a more thorough, documented medical review when the case is more complex or could affect eligibility for benefits. Administrative determinations cover cases that require processing at an administrative level rather than through medical review, often dealing with entitlements or personnel actions rather than a medical causation finding. Because of this structure, the missing type is administrative, completing the established trio. The other options describe what might cause a determination (disease/injury) or are not used terms in this context (general).
