From the EdWeek report:
Please, someone get this to DESE!For low-income students who spent all 12 years of school in districts that increased spending by 20 percent, graduation rates rose by 23 percentage points. Due to the measurement error or “noise” found in almost any study of this type, the effect could, very plausibly, be as low as 8.7 percentage points and as high as 37 percentage points. The estimates are based on the study’s analysis of 15,000 children born between 1955 and 1985. All account for a host of other potential explanations, such as school desegregation, War on Poverty programs, and demographic changes.The paper’s analysis also found that low-income children who were exposed to a 20 percent spending increase for their entire school careers attained nearly a full year of additional education after high school. (That estimate ranged from about four months to 1½ years.)Between the ages of 25 and 45, these same children were 20 percentage points less likely to fall into poverty during any given year. (Estimates vary from 8 percentage points to 31 percentage points.) Their individual wages were 25 percent higher than they would have been without the changes, with estimates ranging from 3 percent to 45 percent, according to the paper. And their family incomes were 52 percent higher, with estimates ranging from 17 percent to 86 percent.
