The base index is calculated by averaging the percent increases in the Pennsylvania statewide average weekly wage and the Federal employment cost index for elementary/secondary schools.
Additionally, for school districts with a market value/personal income aid ratio (MV/PI AR) greater than 0.4000, the value of their index is adjusted upward by multiplying the base index by the sum of 0.75 and their MV/PI AR. For example, if the base index is 2.4% and the school district's MV/PI AR is 0.6000, the school district's adjusted index is 2.4% x (0.75 + 0.6000) = 3.2%.
