What is the MV/PI Aid Ratio?
What is MV/PI Aid Ratio? MV/PI Aid Ratio—or Market Value/Personal Income Aid Ratio—is a measure of local wealth that has been used in several education funding formulas for decades. The measure, which is a combination of a Market Value Aid Ratio and a Personal Income Aid Ratio, has a scale of 0.15 to 1, and it reflects the general wealth of the school district based a school district’s total market value and personal income per student in comparison to the state total market value and personal income per student.
A school district with a low MV/PI Aid Ratio is relatively wealthy. A high MV/PI Aid Ratio reflect low local wealth. For 2018-19, the MV/PI Aid Ratio ranges from 0.15 in many of the state’s wealthiest school districts to a high of 0.8983 in the poorest school district—Reading School District.

As an important aside, while an accurate reflection of local wealth in many school districts, the MV/PI Aid Ratio produces some surprising results in others, making it a problematic factor when defining local wealth in all 500 school districts. The basic education funding formula solved this problem by using the Median Household Income Index, which provides a much more accurate representation of "local wealth" across all school districts.
