I believe that those scores can get your DS into just about any gifted program, including DYS, that will accept them. Not only is the GAI high enough for DYS, but so is the PRI. So great scores!

Have you done achievement testing or do you plan to? I would think that an individual achievement test might be a better bet than a Talent Search (which is tightly timed, unless you can get accomodations). Best wishes!
