[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Does anyone else have a child who consistently scores at the top on standardized tests but did very poorly on the CogAT? Our DC (currently in a DCC CES) [b]bombed the nonverbal and quantitative sections,[/b] and his verbal was lower too. He didn't get into either magnet. We weren't counting on his getting in, but it was disconcerting to see the [b]scores so much lower[/b].[/quote]

When you say he "bombed" are you talking about his national percentile or his MCPS percentile?  Scores "so much lower" than what?

Because if you are talking about the MCPS percentile, remember that is comparing your son to only students in MCPS who were invited to test due to strong academic data and/or whose parents requested testing-- less than half of the current 5th grade class.  So, you would expect lower percentiles when you are changing the group you are comparing against. This group already removed most of the "outliers" who would typically score in the lower quartile- percentiles are like the old bell curve- some are at the top, most in the middle and a few at the bottom- so when MCPS is only looking at what would typically be their top half, the distribution of scores is going to change.

I was talking about the MCPS percentiles. Thanks for this context - it makes more sense now. [/quote]

Chiming in to say, you have to rethink all the previous standardized scores and wonder how they'd rank with respect to this population.  MCPS has this information since they have PARCC scores, etc., for the entire applicant pool.  If it's around 4000 kids in the pool, then rule of thumb would be needing 95th percentile on any given measure, bellow that there's enough kids to fill a given magnet who scored higher.[/quote]
