Thanks, all! Dottie/Grinity, what are the options for achievement tests? Also, in your experience, what is a "normal" path for a 145 level kid - grade accel, subject matter, etc.?
Also, would he be eligible for extended norms testing?
I'm not Grinity or Dottie, but I'll chime in too. The extended norms can be figured from the testing he's already had if his scores are eligible. Some 18s and 19s are, some aren't. It falls back on the scaled numbers, I believe. Do you have more data than just the subtest totals?
In terms of achievement tests, I'd take a look at the DYS criteria and have him take one of those. If you're looking at applying before the next round of talent search testing in the winter of next year, I'd go with the WIAT or WJ. If you feel that you can wait, the EXPLORE might give you more info than the WJ or WIAT b/c it isn't such a brief test and it will compare him to 8th graders on an 8th grade test which may give you good insight into how much he has self taught.
In re to what a 145+ kid needs, my personal opinion would be that it is very individual but you can safely assume that it is going to involve some form of acceleration whether that be subject acceleration or grade acceleration or something else. One of my girls isn't in that range but is more than moderately gifted and she has done well with a single grade skip. My other dd has been IQ tested twice -- once with scores in that range and once not. However, both times she was very erratic within subtests and much lower on PSI and WMI than PRI and VCI. B/c she is already very young for grade and has ADD and anxiety and the achievement scores fall more in that "predicted range" for HG kids like Dottie mentioned (135-140), she's done fine with GT reading classes and subject acceleration in math only. She's not likely to need or want anything more than that.
It looks like your ds is more well rounded and not as erratic as my kids, though, and if his achievement is up there too, I would at least take a look at a grade skip and see what you and he think after exploring it more.
eta: I see that Dottie beat me to responding while I was typing!
