Welcome! Here are a couple books I found helpful, and a link to hoagies, the everything-gifted site:
Miraca Gross - Exceptionally Gifted Children (I recommend getting this at the library - it's out of print and pretty pricey!)
Deborah Ruf - Losing Our Minds (wonderful for understanding the different levels of giftedness)
Hoagies Gifted - Highly/Profoundly Gifted We have a DS5 who is set to go to kindergarten in the fall, and our local district was very helpful. They gave him WJ-III achievement testing (free - yay!) and are planning to give him differentiated work in math and reading.
I also might have missed this due to skimming, but what prompted you to seek out the gifted testing? Troubles at school? Good luck with all of this. Parents of GT kids have a wonderful resource in this site, with all its helpful parents who have been there, done that.
