I see the distinction between intelligence and rationality as assuming a model of an agent with a part that generates logical information and a part that uses the logical information to arrive at beliefs and decisions, with “intelligence” defined as the quality of the former part and “rationality” defined as the quality of the latter part. In the latter case “quality” turns out to mean something like “closeness to expected utility maximization and probability theory”.
That makes intelligence an internal sub-module, that is some distance from actions, and so can’t directly be measured by tests. That is not what most scientists use the term to mean, I believe.
