State aid is complex.
That said, there are a few important issues that must be fixed ASAP to make it more equitable: 
ISSUE:  To decide funding, poverty levels are determined using outdated information from the 2000 Census.
FIX:  Use the most recent data (obviously).

ISSUE The state thinks our cost of living in Westchester is equal to other parts of the Hudson Valley (Ulster, Dutchess, etc.).
FIX:  Change the Regional Cost Index (RCI) to reflect Westchester's true costs.

ISSUE:  Added costs incurred to properly educate English Language Learners (ELLs) are insufficiently funded by NY State.
FIX:  Increase funding for school districts that have a significant percentage of ELLs.
