[quote=Anonymous][quote=Anonymous][quote=Anonymous]Can anyone from McKinley explain this talking point: APS’s two proposals do not leverage excess capacity in the NW part of the county—in fact, they create an even bigger surplus of seats in the NW part of Arlington. What’s more,the “Representative Boundary”scenario[no school moves] actually generates a higher positive seat differential (369 seats) in the Rosslyn-Ballston corridor than either Proposal 1 (276 seats) or Proposal 2 (315 seats).

It doesn't make any sense at all. You're saying that there are more neighborhood seats in the RB corridor with Key as option and that somehow having McKinley as neighborhood decreases the total number of seats in the west?[/quote]

It's because McKinley isn't using the zone maps properly.  While the zone boundaries follow current schools boundaries, what APS is actually calculating is the difference between the number of neighborhood school seats in a particular zone as compared to the projected number of students in all of the planning units in that zone.  When McKinley overlaid their own calculations, instead of continuing to use that formula (thus making it an apples-to-apples comparison), they didn't follow the zone boundaries for calculating the number of students.  Instead, they looked at the potential boundaries laid out in the representative boundary scenario and the other spreadsheet for proposals one and two, and calculated the projected number of students in each school zone.

So, for instance, in the representative boundary scenario, McKinley's border has to reach way into south Arlington to fill the school because there would be such an excess of seats.  What McKinley did in their calculations was move all of those kids from Zone 3 into Zone 1 (since they'd be zoned for McKinley rather than Carlin Springs), making it look like Zone 3 would have a much greater surplus of seats and Zone 1 a far smaller surplus of seats than the zones actually would).

I don't know if the McKinley people who put it together were being disingenuous or just fundamentally don't understand the data analysis, but either way their analysis simply isn't credible or reliable.[/quote]

By APS' own admission, the Zone Map is purely subjective. [/quote]
