What is your source for this claim (that the 91st percentile is 43/60)? The University of Iowa's interpretation guide lists the 91% percentile as a SS of 170 (Table A2), and Table A1 shows that 50/60 corresponds to that SS. So the 91st percentile is 50 out of 60. |
The SAT is also a measure of college readiness, so you shouldn't prep for that either by your logic. I prepped my kid for IAAT, and he is getting As in the class. I suspect he would not have passed without the prep, but no way to know for sure. |
![]() Imagine if this attitude existed in sports. |
I agree with the overall sentiment. In some cases it doesn't apply though. I advised one parent to appeal to get into algebra, because probably his kid is capable, but he did not score well enough on the pretest to be eligible. |
There is an IAAT book you can buy on amazon . |
That link is for IARA, not IAAT. They’re different tests. |
No, they're not. Also, thinking that 43/60 is the 91st percentile shows you lack mathematical sense. |
43/60 could be the 91st percentile. 30/60 could be the 91st percentile is the test is hard enough for the norming population. |
What are you even talking about? The post stating that 43/60 is the 91st percentile is from over 3 years ago. The PP is long gone. |
Ya, ignore them. They just don't want others to do well, so they intentionally dispense bad advice. |
For what it's worth - my DD got a 95% and I requested a copy of the raw data from the school. She got a 52/60. |
... which is 100% consistent with tables A1/A2 in the IARA Interpretation Guide. IARA and IAAT are the same test and use the same conversion tables. |
They're just trying to make their own kid look better by tearing down others. The prep war is on and pretending it isn't is only going to hurt your child's chances since they're are competing against many kids whose parents have sunk tens of thousands into outside enrichment. |
So what that 91st percentile is 43/60? The test makers have determined that at that point you’re ready for Algebra. What’s your uneducated point? |
