Chart: Weighted Funding
All but seven states apply some sort of weight or adjustment in their school finance formulas to provide additional funds for districts with certain characteristics. Typically states calculate a weighted enrollment by assigning specified groups of students a numeric weight, which causes the members of that group to count as more than one student. The specific way the adjustment is applied and the actual numeric weight used vary greatly across the states.
