So what do you do about the two kids who test at the same age, one on the old version one on the new. The first kid qualifies for DYS, grade skip, and/or HG magnet, the second kid qualifies for no GT programs or grade skip based on school rules. For purposes of this example, if they had each taken the same test, they would have gotten the same scores. Or similarly, a kid who gets 130 on the old test and another kid who gets 115 on the new test. Which kids are in the correct educational setting? We cannot tell based on IQ score alone.
I guess I'm more concerned for the kids who are getting the lower scores, which may not get them into programs they need.
Me too, the problem with renorming is that the bar at 2% (or whatever %) keeps raising and kids with needs are now falling below it and may not be getting the support they need. As you point out, it also helps illustrate that IQ scores are not sufficient screening.
Now if the mean population being targeted by standard curriculum actually followed the group mean, then the relative outliers argument would seem valid, but I don't get the sense that schools in general have been "smartening up" their core focus.
