40% weighted adjustment for students in poverty
Unweighted adjustment for students in poverty
NOTE: Percent difference was calculated by dividing the difference between expenditures in the highest-poverty districts from that in lowest-poverty districts by the expenditures in lowest-poverty districts. A positive percentage indicates that the highest-poverty districts spent more money per pupil than the lowest-poverty districts. A negative percentage indicates that the highest-poverty districts spent less money per pupil than the lowest-poverty districts.
Based on an assumption that additional per-pupil spending is appropriate to meet the additional needs of students in poverty, the Dashboard indicator weights the number of poor students, defaulting to a factor of 40% (taken from the Department's Title I formula) when calculating per-pupil expenditures. Users may use alternative weights, including no additional weight, if they prefer.
