Which one of the following is NOT one of the four functions of claim investigation?

The function that is not one of the four core functions of claim investigation is disposition. The claim investigation process typically includes adjustment, evaluation, and interviewing.

Adjustment refers to the process of assessing the value of the claim and determining how much the insurance company might pay out based on the facts gathered. Evaluation involves analyzing the findings of the investigation to verify the legitimacy of the claim and the extent of the loss or damage. Interviewing is a crucial aspect where the claims adjuster or investigator communicates with the claimant and witnesses to gather additional information that may influence the decision on the claim.

Disposition, on the other hand, pertains to the outcome or resolution of the claim rather than an active part of the investigative process. It involves making a decision regarding the claim's approval or denial, which takes place after the functions of adjustment, evaluation, and interviewing have been performed. Therefore, it does not fit within the active investigative roles, making it the correct answer to the question posed.
