I’m also not sure what real info comes from that chart. Those are the kids who were seriously considered from each school, and what put them into consideration. Many kids were probably in consideration based on every one of those measures. But it still doesn’t show who was selected or why. Or am I misunderstanding?[/quote]

I think the chart is meant to show that there is talent and promise all over the county. You are of course right, though, that is is showing the 99th (or maybe even something like >97th) percentiles and not the 99.9th. But it was put out by MCPS at a time when a lot of folks seem to be publicly aghast at the idea that there might be bright and underchallenged kids who would benefit from the magnet at even the most high needs schools.

Ah, that makes sense.[/quote]

But none of the tests used by mcps are designed [b]to distinguish any part of the 99th percentile from another part of the 99th percentile.[/b]  Oh well.  Stats you know....[/quote]
What are you talking about? CogAt raw scores distinguish within the 99th percentile, so do MAPs and PARCCs. A child with 300 MAP-M in the fall is, obviously, different from the child with 240 MAP-M while both numbers fall under 99 percentile.[/quote]

There is little statistical validity to those distinctions - so say statistics  AND the creators of those tests.  Thus they all say you must use multiple measures.[/quote]
