I think WISC 4 is good for kids who are talkative with strangers. It is commonly offered and widely familiar. I think you have the key issue....is your daughter optimally gifted and going to do well with strong agemates or is your child highly or unusually gifted so a totally flexible approach.
I'm not much of a fan of asking a teacher to provide a totally unique educationall experience for an individual kid...some teachers are super and do it without even asking or making a big deal out of it but it is just too difficult for most teachers....like asking a malpractice lawyer to handle a divorce. That is why I believe in putting kids with similar readyness to learn levels together. How this is accomplished can be through choosing a school with similar agemates or through placing the child with older children for some or all of the day or some combination.
I appreciate that you care so much about your kids!
