Testing was useful for us too. For a reason, just like Kriston suggested. My DD5 was complaining about how simple the K work was for her, we already knew that she was gifted we just didn't relized how gifted until after the testing (and after I read the book by Ruf). The type of testing we had done for her was just to identify what grade level she was at with all the subjects, nothing to grueling. It gave us the information we needed to make a decission in her education. If you are looking for testing with an IQ score the tester suggested 6 or 7.
