The GE's should always correspond with their related AE for that subtest. A GE of 5th-something won't necessarly match the scaled score from reading to math. But the only difference in GE's and AE's is in the reporting. They are like Scaled Scores and percentiles. The one governs the other.
And the GE/AE scores are based solely on the raw score, and should match for whomever takes the test. For example, an average child in 3rd grade would get the GE of 3.6 and a scaled score in the 100 range. A bright 5 year old with the exact same raw score will also get the GE of 3.6, but his scaled score will be significantly higher. Make sense?
This makes perfect sense and that's what I thought. If this wasn't true I would be really pulling my hair off.
You will get different percentiles if you use age based versus grade based, but for an "age appropriate" child, those differences should be negligible. Still, age based scores are considered the most accurate.
You mean that I would get different results using the same test scores if I normed them against my son's age than if I normed them against his grade? (I would still get the same GE but different scale and %) I would probably get
very different scale numbers? That's insane. I mean the same child, the same raw scores, the same GE but different numbers?
It makes me wonder if the psychologist based my son's scores on grade since crisc mentioned that the tester couldn't put the grade equivalent in and had to use the age. Looking at our numbers it's probably the case: 2 months of age difference, a huge scale difference and 9 months in GE just don't add up. If you talk about 5.1 and average K then it's a different age story.
I am not hunting for higher numbers, I really am not. I just want to get a clue how things work. It's my math/logic background talking. I need to know how things work

I assumed that the test was based on the age only and gives only one result but 2 different scales ... This makes it even harder to compare any results.
Interesting!!! Again, please don't split hairs. Both of your son's are phenomenally bright, and they now have the test results to prove it! I would expect them both to test "lower" in time on the scaled scores (just because of the way the tests work), but both will most likely continue to lead the pack by a good margin.
Honestly, the only thing which matters right now is the DYS score. The school cares about GE anyway. I assume the numbers will come down and I better not to even think that age wise his numbers could have been most likely much higher. That would probably freak me out I am scared about his school future as it is.
crisc, wouldn't it be lovely to get our sons together? I think they would have lots of to talk about
