On some level, yes, any good examiner should be able to assess gifted kids. Where it may make a difference:
1. Queries: some items allow asking for clarification or elaboration, and although there are guidelines for the kinds of responses that should always be queried, GT examinees sometimes give divergent responses that are correct, but not as conventionally so. These should be queried for the underlying reasoning, which may be sound, if unusual.
2. Tells: although all examiners are supposed to be neutral in their testing behavior, so as not to signal anything about the accuracy of performance back to the examinee, in practice many examiners have tells, or can be careless about how thoroughly they screen the record form from the examinee. The majority of NT or learning impaired children will not pick up on these little tells. GT children are another story, and have a high potential for having their responses affected (both positively and negatively) by this unconscious examiner feedback.
3. Interpretation: Yes, it does make a difference when it comes to test interpretation, especially for 2e students, not only in terms of score interpretation, but also in terms of testing behavior.
