[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]West Springfield is more diverse than Yorktown and has a GS score of 8.  [/quote]

GS is measuring performance gap, not performance.

+1. People still aren't getting it. You have to think of it like an inverse bell curve. At the extremes, either highly diverse (which tends to result in all students being clustered roughly together on the advantage scale) and almost completely homogenous (where there are too few disadvantaged students to be counted), GS scores will be higher because of the equity measurement. For those schools in between that are diverse enough for the impact to be measurable but where there's a significant advantage gap within the student body, equity scores will dip and will drag down the overall score. For school systems that care about GS scores, this provides an incentive to create zone schools to concentrate the affluent in some schools with no more than a handful of disadvantaged students to be measured and drag down the rating, and then cluster all of the less-affluent students together so that their lower test scores will be closer together. Gives the appearance of equity when really it's highly segregated.[/quote]

Well don’t you worry.  They’ve kicked all those poor kids out of Yorktown for the next boundary shift.
So your scores will be back up in no time.  :roll: [/quote]

I don't care about the GS scores because I know they're a flawed methodology. If the scores start to climb as the boundary shift rolls out, I'm indifferent to that. I'm simply pointing out to the FCPS boosters the flaws in their arguments.[/quote]
