    My DS took the CogAT Form 6 Level 1 as part of a GT process for school when he was 6.5 years old. I requested a copy of his (manually scored) CogAT score report. It looks reasonable. One part struck me as slightly odd, so I thought I'd ask if anyone here has an opinion about it.

    For a raw score of 42 correct out of 44 questions on the Nonverbal subtest, these derived statistics were given:

    Universal Scale Score (USS) = 199
    Standard Age Score (SAS) = 127
    Percentile = 95%
    Stanine = 8

    It surprised me that missing two questions on the Nonverbal subtest was enough to drop the percentile for that subtest down to 95%. DS missed one question each on the other two CogAT subtests, Verbal and Quantitative. The percentiles given for those subtests were each 99%. I would guess the percentile and stanine are age-based rather than grade-based, and that the test was scored using the 2005 Norms.

    Does 95% seem reasonable for a 42 / 44 Nonverbal raw score? If so, the CogAT is more sensitive than I would have guessed. Does anyone have any insights or related score data they would be willing to share?

    Thanks.

    If I remember correctly, more points are taken off if the question was answered incorrectly than unanswered.

    I'm not too sure if each question carry different weights.

Students can get the same scaled score by getting fewer items correct on the higher level.

    What's above level? Is the CogAT age- or grade-based? DS9 will have to take this test in a new school for GT program identification. He's skipped 4th and will be in 5th this year. I'm wondering if he will be given an above level test because he'll be in 5th?? It would really suck if he didn't meet the criteria for GT, yet was grade-skipped, LOL!

The advantage is against himself on a lower level, not necessarily his new peers, but he'll be better off with the higher level (if I'm understanding it correctly). The harder questions will give him more room for error as well as more room to excel. Let's say there are 50 questions. On the lower level, he might need 45 of those to get a 130 score. On the high :)er level, he might only need 40. Does that make sense?

    Yep, the last part makes sense. Thanks.

    Let me see if I understand the first part blush... Since he's in 5th grade, he'd take whatever level is administered there, but the scoring may be done based on age norms? Which would mean he had the 'wiggle room' (using your example of only needing 40 correct) of the above level test? Sorry if I'm not understanding, I'm trying... And I should probably say that I'm not really all that concerned about him qualifying or not, I just like to understand things like this. smile

    Thanks for taking the time.

    Thanks for the explanations and the article. Long, but interesting.

    We'll just have to wait and see what happens when testing time comes around.
