Hi elizabethmom --
My ds6 took the WPPSI at 5y5m, with a WPPSI full-scale of 148 and slightly lower VIQ and PIQ scores. He hit ceilings on 7 subtests, and I hoped the DYS people would consider possible ceiling effects. His achievement scores were well over their cut-offs (yes, achievement scores aren't as telling with younger children). We got the "need more information" letter when we submitted those scores.
DS was admitted after I sent a pretty strong portfolio, so it can be done, but in ds's situation they didn't look at possible ceiling effects. To pull off higher than 150 with ceiling effects, I think the child would need to have a pretty high PSIQ in addition to the high "ceilinged" scores -- thoughts on that, Dottie? Does that even make sense?
Anyway, elizabethmom! Your dd1 has scores that *are* over DYS cut-offs (that 152 is impressive), so if you want to wait on achievement testing you could try applying with her VIQ and a portfolio. The "Application Process" page says:
Please submit at least two of the following as evidence of intellectual precocity. ...
* A full written report for an individually administered IQ (intelligence) test from the Qualifying Tests and Score Guidelines on the next page. ...
*A score report for a talent/search college placement test from the Qualifying Tests and Score Guidelines OR a full written report for an individually administered achievement test from the Qualifying Tests and Score Guidelines on the next page. ...
* A portfolio with three original pieces of the applicant�s work that demonstrate his/her advanced precocity. In order for the Applications Review Committee to best assess the applicant�s abilities, please submit work that showcases your child�s academic areas of strength. ...
So a good portfolio might be all dd1 needs. They'll ask for more info if they want it. I'd bet they'll ask for more testing for your dd2, but you could try it.
As for wanting to test with higher ceilings ... yes! For my situation, we have no reason to test other than pure curiosity, so we're not pursuing it. Personally I think ds6's WPPSI score isn't very far off the mark. He *might* have picked up a few points, but I don't think all that many, on a test with a higher ceiling. And since he doesn't need another score for DYS, we've got no reason to retest. TBH, I wouldn't be terribly surprised if he scored a bit lower on a WISC, which is right in line with DYS requirements.
That said, if we had to have him tested with a WISC or SB5 for some program or something, I can't say I'd be disappointed! I would probably have invented a reason to retest at some point to try for DYS scores.
I'm curious; I'm a numbers person!
