that's all
The WISC-IV is an IQ test and if the child came out in the top 2% or so on it, I would absolutely say that the child is gifted unless there was a problem with test administration, significant test prepping, or it looked like a weird outlier score (i.e. -- all other data says that the child isn't gifted and this is the only piece that has ever indicated s/he is gifted).

The CAT (again, do we mean CogAT or an achievement test) is not an IQ test. Whether it is the CogAT or the CAT, neither one tests IQ. The CogAT tests "developed abilities" and gifted children may not score similarly on that test vs. an IQ test. See this article for more info.
