How we choose to use a term depends on what we want to do with it. If validity is to be used to support a score interpretation, validation would require an analysis of the plausibility of that interpretation. If validity is to be used to support score uses, validation would require an analysis of the appropriateness of the proposed uses, and therefore, would require an analysis of the consequences of the uses. In each case, the evidence need for validation would depend on the specific claims being made.
