  • 2. School Choice and Admissions Distance-based admissions policies hierarchies of school popularity lead to the reproduction of social inequalityhttp://landscapemodelling.netIGU 2013 | Leeds, UK | 01/06/13
  • 3. The Admissions Processhttp://landscapemodelling.net Other boroughs account for: Special Educational Needs Medical/Social Needs SiblingsIGU 2013 | Leeds, UK | 01/06/13

  • 8. Parental Aspirationhttp://landscapemodelling.net“I don’t want my kids towork in the supermarket.I want my sons tobecome a doctor, or apilot or something likethat.” [p.102]“I just want them to behappy and enjoy their lifeand obviously, yes, dowell at school but so longas they’re happy” [p.104]IGU 2013 | Leeds, UK | 01/06/13
  • 9. Parental Aspiration“I think [education is] reasonably important. Iwouldn’t put it up there as really top ranked justbecause, you know, I think there’s moreimportant things in a child’s life. As long as yourchild is well adjusted and doesn’t suffer inschool think, you know, the school isappropriate” [p.105]“Oh, the single most important thing that aparent can give to their children in life is a first-class education” [p.98]http://landscapemodelling.netIGU 2013 | Leeds, UK | 01/06/13
  • 10. Parental Aspiration“My gift to my children…you could sayinheritance, what I pass on to them, is thatthey’ve all achieved a university education. Ifthey’ve done that then I’ll feel I’ve done my bitas a parent” [p.101]“I’d like [my daughter] to go to university but ifshe didn’t it wouldn’t be the end of the world.”[p.104]http://landscapemodelling.netIGU 2013 | Leeds, UK | 01/06/13
  • 11. Model Structurehttp://landscapemodelling.net Family Attributes Aspiration Child Age Location Attainment Strategy Rankings Catchment (schools) Satisfactory (schools) Avoided (schools) School Attributes Value-added Location GCSE score Available Places List of applicants List of allocated pupils(i.e., families)IGU 2013 | Leeds, UK | 01/06/13
  • 12. Model Procedures Families rank schools for moving & applying Families can move once prior to application Move anywhere or only into areas with lower orequal aspiration (location constraints) Schools allocate places to applicants basedon distance alone School value-added influences pupilattainmenthttp://landscapemodelling.netIGU 2013 | Leeds, UK | 01/06/13

  • 15. Model Analysis Reproduction of system-level patterns Identify necessary structures and rules Identify agent-level patterns Which agents move? Which agents fail to secure preferred school? Explore implications of policy scenarios Closing poor schools Improving school value-addedhttp://landscapemodelling.netIGU 2013 | Leeds, UK | 01/06/13
  • 16. System-Level Analysis What conditions needed to reproduceempirical system-level patterns? Variation in school value-added? Constraints on family movement? Examine combinations of rules No value-added (nVA), no location constraints (nLC) Value-added (VA), no location constraints (nLC) No value-added (nVA), location constraints (LC) Value-added (VA), movement constraints (LC)http://landscapemodelling.netIGU 2013 | Leeds, UK | 01/06/13
