and if you read the OP, the author was trying to convince people that FCPS is now asking who has seen the test, the implication apparently being that they are seeing who has been naughty and nice. And maybe taking names? And maybe acting accordingly? |

Right, and here's what FCPS says about this:
Here's a link to a FCPS document that includes an explanation of why the test was changed last year: http://www.fcps.edu/is/aap/pdfs/FAQre2012CustomizedCogAT.pdf See fourth paragraph, first sentence: "FCPS staff members chose to administer the custom form of the CogAT this year after it came to our attention that some students, in previous years, had prepared for the CogAT using the exact form of the CogAT being administered in FCPS." |
|
FCPS knows that these scores are less reliable for kids who have studied old versions of the test. That is why they changed to a different version. |
I would like to see the results of this study, just out of interest. I don't think the school district would use the results in the identification process, but it may be useful in making future decisions about the process and whether changes should be made. |
The CogAt is not an intelligence test. It's simply a test of reasoning ability. Kids who score high on the CogAt are not necessarily any smarter than those who don't. |
|
The CogAT is not an Intelligence test. But FCPS is using as a proxy for intelligence, as they have no better measure that is affordable. The CogAT scores should scale with intelligence, but also be impacted by other factors, such as prep. That is why fcps does not want prep: it makes the CogAT less reliable in measuring Intelligence. (I am the poster that said it is being used as an intelligence test). |
so you're saying that someone can prep for an intelligence test? |
I am saying that it is possible to increase the number of correct answers on an intelligence test. But it does not increase the intelligence; rather, it indicates that the tests are not perfect. A test like the CogAT/FxAT is easier to prepare for than an individually administered test like the WISC, but any test/measurement can be skewed. Just like I can make most quartz watches run slow by placing them in the freezer. Or I can make my car's MPG go up by driving slower. It is possible to bias any measurement. This is why prepping for the CogAT is looked upon so negatively: The county wants the Intelligence from the CogAT. What they get is a measure of problem solving and test prep. Problem solving is probably related to intelligence, as well as other factors (e.g., distractions, sleep the night before, blood sugar, and Prepping). If you prep, the county may assume you to be smarter than you are, but that does not actually make you smarted. |
Real IQ tests are individually administered. They interact, ask questions and observe the person taking the test. The people giving it are well trained in spotting kids that have been prepped. The CogAT is a group test, no individual attention is given and thus is MUCH easier to prep for. |
Our hockey, baseball, swimming, and Taekwondo teams all offer private lessons. Where do you live? Not around Reston that's for sure.... |
The definition of a subjective and biased evaluation (observer and test bias) |
Oh, don't worry about the ole goat. A space cadet in outer space who has surfed these boards for a decade. |
No one can prep for an intelligence, IQ or aptitude test. Intelligence is fixed. You can't have more than your parents gave you. It's like fat and obesity. Fixed. |
well then the CogAt can't be an intelligence test then. So what's all the brouhaha about? |
