[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Our school AART teacher said the lowest score she saw in the accepted students last year is 142. That seems unrealistic high for me.[/quote]

She probably mis-spoke and meant to say 132. That number would make sense for a higher-SES school.[/quote]

I doubt she mis-spoke, there are schools where a 142 would be the norm.[/quote]

Which is why the test scores have become meaningless and irrelevant.  Parents broke them.[/quote]

I am not so sure parents broke them.  My kid goes to a very high SES school (i.e. 1% of kids are free an reduced meals), and he scored right around there.  All we did was some practice problems from a $5 workbook. We did not even finish the workbook because it was clear he understood.  I really don’t know any of his friends who were going to test prep places and we do lots of car pools for activities, so I am looped into a lot of family schedules. I would not doubt many of his friends also scored that high.  They are smart kids. There are just a lot of really smart and accomplished people around here. Intelligence is due both to heredity and environment, the latter of which means so much more than an hour of test prep. Kids in this school have a lot going for them without a lot of prep.

I am glad America will have these future leaders.  Why is that a bad thing? We should celebrate their emerging capacity.[/quote]

To sum: The lies we tell ourselves to justify prepping for aptitude tests.[/quote]

Eh, I can fully buy that there are kids who score high with the workbooks and no prep classes. [b]Kids whose parents have been reading to them and finding ways for them to practice math are in a better place for the CoGAT, regardless of prep. [/b]We know that higher SES families are more likely to have been reading to kids and practicing math. I know that there are parents who send their kids to prep classes but not every high score is a prep class. The work books are effective and less expensive.

I don’t buy the CoGAT as an IQ test because it is too easily influenced. [/quote]

This. The CogAT is an achievement test, not an IQ test.  It's scaled like an IQ test and there's a correlation between CogAT and WISC scores, but kids in higher-performing schools who've had more enrichment at home will score better, even without actual prep.  FCPS absolutely did the right thing by establishing local norms.

I hate to tell you guys but did I an NNAT and COGAT prep books myself, as an adult, and these most certainly ARE IQ tests. There is not just a correlation - it is an extremely extremely high correlation. HAve you never taken an IQ test to not know that the problems they give you are the exact same problems?! https://www.hmhco.com/~/media/sites/home/hmh-assessments/assessments/cogat/pdf/cogat-cognitively-speaking-v6-winter-2008.pdf?la=en

I hate to tell you this, but you're flat out wrong.  The CogAT is absolutely not an IQ test.  A simple google search for "Is the CogAT an IQ test will turn up numerous sites that explicitly state that it is not.

There is some similarity between CogAT problems and IQ problems.  The CogAT certainly doesn't assess enough domains and isn't thorough enough to give an IQ.  At best, it would be the cliff notes version of an IQ test, but it really isn't even that.  [/quote]

The correlation between NNAT and Raven Progressive Matrices, which measures IQ, is 0.84 my friend. You can't get much higher than that - even test-retest correlations on the same IQ test aren't typically higher than that.  Can't find it for CogAT but presumably the nonverbal correlation would be equally high given that NNAT is generally perceived as less reliable
