13. C0910_ChartDistance_Enroll (index measuring distance to nearby charter-only districts, weighted by charter enrollment)

14. C0910_ChartDistance_Enroll_Rel (index measuring distance to nearby charter-only districts, weighted by charter enrollment relative to district’s enrollment)

15. C_State (state)

16. C_Locale_Type (type of locale as defined in CCD)

The “With FRPL” models add the following covariates:

19. C0910_Num_Free (number of students certified for free meals)

20. C0910_Num_Reduced (number of students certified for reduced-price meals)

21. C0910_ChartDistance_FRPL (index measuring distance to nearby charter-only districts, weighted by number of charter students certified for free or reduced-price meals)

22. C0910_ChartDistance_FRPL_Rel (index measuring distance to nearby charter-only districts, weighted by number of charter students certified for free or reduced-price meals relative to number in district)

23. C0910_Need (categorical variable for whether percentage of students certified for free or reduced-price meals is < 50, 50-74, or ≥ 75)
