[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote]This is EXACTLY what MCPS wanted to achieve by creating percentiles within SES bands. The average person is now totally confused about the fact that a child can score "99%" in a low SES band, but really have a score in the 80s when compared to the entire district. Now we have all of the "high performers" that we could possibly want![/quote]

There's no evidence of this happening, by the way. I have a kid admitted to TPMS with a 99% in a low SES band. They are also 99% nationally, and within their SAS. Now, MCPS doesn't actually show "compared to the entire district" but it stands to reason that a kid who is at 99% nationally is definitely not "in the 80s" when compared to the entire district.

I think you're confused PP. This is the way it's supposed to work. Your child has an advantage and more likely to score 99th percentile in the lower SES band. Likely his scores would be lower in a high SES band.
I know of kids who scored 99th percentile nationally in a subtest and that matched up to 80 something in their high SES band.[/quote]

Oh, that may be true but that's not what PP said. PP said that a 99th percentile in a low SES band would be "in the 80s" county-wide. But that's not the case, assuming the national percentiles are more or less a decent proxy for county-wide percentiles. We don't know how MCPS county-wide percentiles line up with national percentiles for Cogat, but we do know they more or less line up for MAP.

But, yes, if the question is whether my 99th percentile nationally kid would be lower if he was at Pyle rather than his home school? Almost certainly, but again that wasn't the assertion above. [/quote]

Sorry, I think you're the one that's confused. The child at the lower SES band school is at a disadvantage because they're at a lower-rated school. This is why some people pay a premium to live in certain school boundaries.  The cohort criteria simply normalizes these differences so that all students have the same chances regardless of their privilege.[/quote]
