Now based on updated 2020 Boundary Planning Process Data.
APS description of the data is here. Choose school.
Left-click on planning unit to assign the school. Right click to increase number
of option students by five. Once the number of option students is greater than the number of total students, option students are reset to zero. Reload page
to reset values.
Hover over a planning unit to get statistics about that planning unit ("Hover for Planning Unit Info" must be checked).
Select a school from the dropdown menu on the upper left. If you click on a planning unit, that planning unit will be assigned to the school from the dropdown menu. All units
that are part of the school selected will be highlighted on the map.
Table of planning units below populations is refreshed when changes are made. If you have boundaries you like, don't forget to
export them so you can save them. Use the search bar to limit your saved list to certain schools or certain planning unit numbers.
You can choose which schools are option schools at the bottom of the page. Any school that was a neighborhood school that becomes an option school will have all of its
planning units unassigned and must be assigned to a new school by the user.
You can choose the number of preschoolers by school at the bottom of the page.
Right-click on the planning unit to increase number of option students by five. If option students exceed number of students in the planning unit, the number of students will
cycle back down to zero.
Dark lines indicate approximate walk zones. In a few cases, walk zones may split the planning unit, and those cases are not shown, although they are approximated in the tables below.

All default numbers for the option schools are estimated by Arlington Analytics. Total option school attendees are apportioned to option schools proportional
to each school's capacity. This approach may significantly differ from actual outcomes.
We assume that each 18 pre-schoolers displace one 24-person kindergarten classroom; hence, capacity declines by 6 for every 18 pre-school students.
Demographic data for certain types may be censored by APS. Any values between one and nine for
english learning, economically disadvantaged, or disabled student are estimated by Arlington Analytics may differ significantly from the actual, unreported APS values. These values
are denoted with a *.
NOTE: Neighborhood-to-neighborhood transfers not implemented. Demographic data is from the 2018 boundary process (which is from 2017 data); each demographic category is
*not* adjusted for option schools or neighborhood transfers.
