What type of above-grade-level testing would you recommend for an 8 year old boy who does high school math and reads college level books, as well as classic literature? He has skipped one grade but going to 4th grade in 3 weeks in September will be torture for a boy who knows most material already. He has taken a few SAT practice tests and scores with high accuracy for his age – around 660 in math and 450 in English, but we do not necessarily want to put him through SAT for hours with kids much, much older than him. His school does not administer any group tests like ACT Explore or PSAT. Any advice would be tremendously helpful, particularly if you may have had similar experience with your child. Our goal would be to have him tested by a reputable and popular, and wholly recognizable test, to be able to show the school that he will easily manage one more grade skip. Emotionally and academically, the first skip was smooth and easy for him and the school, so we would like to do it again, but we need a good reason to ask for the skip, which can only be supported by a reputable test. We are looking for group tests, not individually administered private tests. Thank you in advance.
