I can't be of much help in suggesting a testing center, sorry. What I can do is give Belin-Blank two enthusiastic thumbs-up.

My DD13 took the Explore through them (back in 4th grade and at a local testing center), and more recently has taken the ACT. B-B provides a report along with scores. While the report is a bit boiler plate, it does have valuable information. Like TIP, or CTY, Belin-Blank also can provide access to other resources and opportunities.

Best of luck,

For gifted children, doing nothing is the wrong choice.
