This document compares zone-based and home-based assignment plans for school choice in Boston. It shows that a zone-based plan with 11 zones results in unequal choice availability and large discontinuities across zone boundaries. A home-based plan provides more gradual variation in school choice across the city without major boundaries. However, it also results in many areas being highly reliant on out-of-zone schools for higher quality options, especially for non-white students.

- 4. 11-Zone Plan Choice Basket ranges from 3 to 16 schools More zones = more boundaries = more discontinuity Unequal number of choices within a zone 4
- 5. 11-Zone: Quality Availability of Tier 1 & 2 range:1 to 9 schools Students near zone boundaries have greatest number of choices 5

- 7. Home-Based/A Choice Basket ranges from 6 to 15 schools Variation more gradual across the city and related to school density and/or lack of quality nearby No major discontinuities at zone boundaries 7
- 8. Home-Based/B Choice Basket ranges from 9 to 18 schools Variation more gradual across the city and related to school density No major discontinuities at zone boundaries 8
- 9. 11-Zone: Quality Tier 1 & 2 availability range: 1 to 9 schools Students near zone boundaries have greatest number of choices 9

- 12. Home-Based/A Walk Zone Reliance Many areas heavily reliant on out-of-walk- zone access to higher quality schools, especially Mattapan, South Boston, Allston/Brighton, East Boston 12
- 13. Home-Based/B: Walk Zone Reliance As requisite number of high-quality schools increases, most areas rely on out-of-walk-zone schools for quality 13
