Regardless of the grades to which these tests are administered, they are normalized by month across the board. There is conjecture here that normalization is only necessary when the gap in age exceeds a grade level. That is just not consistent with nationalized IQ based tests, like the ones mentioned. I guess Fairfax County knows more than the historic IQ testing companies that have been administering, scoring, and developing IQ tests for decades. So you are saying that the NNAT level A, B, C, D, etc. are all the same test? That is not true, each level has a differing number of questions in each of the four sections totaling 38 for each. |
The reason is that the age effect is temporary -- as a PP mentioned age effect goes away around 4th grade -- so you could be keeping out kids who might lag initially but be fine in a year and stellar after that. And you could be letting in seeming stars who will fade in a year or two and be mediocre. That said, there will probably be a lasting effect from this placement now. Those with more potential/intelligence may forever be less than they could have been, and those with less ability may experience lifetime benefits from enrichment that they did not need or deserve the most. Read Outliers by Malcolm Gladwell. |
| Everyone on this board should read that book. It would normalize a lot of the thinking on this topic. |
Excellent response! The huge problam that FCPS created by not adjusting for age is twofold: * firstly, the percentiles of younger kids (say, summer '05) are lower than what they should have been * secondly, the percentiles of older kids (say, Fall of '04, or even earlier if they were redshirted) are higher than what they should have been, as they were now estimated in comparison to a different statistical population. Now that's what I call a huge mess! |
It WOULD be "a huge mess" if Center eligibility were based on a single test score on a single day. But guess what? IT IS NOT. 'Nuff said. |
| PP, that was about the dumbest comment I have heard on this topic yet. One of the cornerstone tests is tainted and you simply point to the NNAT taken in first grade as the fall back. Remember, many cannot afford the WISC, and many do not even understand how to mount an appeal. The school district failed many with their weak ass effort to build a better mouse trap. |
But you don't know that. Adjusting for age might have made very little difference in the numbers of young vs. old 2nd graders who qualified. You just don't have enough information to make the charge that you are making. |
Not the OP but the above argument is really weak. Of course you do not know the magnitude of the effect of this issue, but since all such tests are age-normalized, someone smarter than FCPS must know that there is an effect. And even if this affects less 1% of the kids, it's still more than 100 kids (plus it changes the percentiles for everyone). Otherwise, since no one knows how kids will score, none of these tests would be age-normalized, because nobody would know what the effect might be. Accordingly, we don't know that 3rd grades would do better than 2nd graders in such tests, so let's give them all the same test and not age-adjust... Let's see what happens then! |

Since making the pool based on test scores does not guarantee anything to begin with in regard to aap acceptance, age adjusting is irrelevant.
In the past 40% of non pool kids have made it in AAP. Its laughable to think a couple of percentile points would make any difference in the evaluation process. |
| ITA with pp. If a child needs the AAP class, it will be obvious to the teachers and the test scores will not be on the cusp regardless of age. |
Riiight. With about 17% of kids getting in AAP, the program could probable handle another 20% of the fcps population considering how watered down AAP is to begin with. Granted it might be "obvious" for the top 10% of kids but outside of that not so obvious. |
Where the heck do you dream up this stuff? Now we have a "cornerstone" test and it is "tainted"?!? Sheesh, lady -- you REALLY have to get a freakin' grip on yourself. |
I agree, this is an issue. Yes, the parents can still refer, and yes, being in the pool doesn't mean the committee will select the child. But it still makes sense to expect the test to be age adjusted. I have a 3rd grader with a fall birthday and a 2nd grader with a summer birthday and I can see a difference in having the older vs. younger child for their grade. My current 2nd grader with the summer birthday got a 90 CogAT but got in the pool with her 99 percentile NNAT score. I imagine the GRBS will be important to her application. |
+1000. FCPS bungled the FFX CogAT. They ought to age norm it. I would say pure incompetence and may try to cover up by *sacrificing* younger kids. Please call the AART and ask them to pass on the age norming issue to the Central Screening committee. |
Does anybody really know if the test was age normed or not? Perhaps it can't be since there's no national sample to compare against. |
