Communities perceived to have more ability to fund services on their own — i.e., having higher per capita income and property values – receive less aid under the Chapter 70 education formula. Since that formula is now the principal conduit for state aid, total state aid tilts more heavily towards poorer communities than it did in the past.
Those communities that do not do well under the Chapter 70 formula but used to do well under the Additional Assistance formula have seen a marked decline in local aid over the last decade as Additional Assistance has been phased in favor of Chapter 70. Arlington and Cambridge are among those communities — see the chart below or click here for a spreadsheet with the underlying data. The spreadsheet includes Additional Assistance per capita rankings from 2002. These rankings confirm that the communities with the sharpest declines include many of those that did best under the additional assistance formula.
