Quality Counts report

This annual looks at the steps states are taking to turn ESSA's blueprint into a finished structure—and the challenges of doing it by the 2017-18 school year. The report also features comprehensive, summative grades for the nation and the states on a range of custom indicators developed over the years by the Education Week Research Center: the Chance-for-Success Index, the K-12 Achievement Index, and the school finance analysis.

Graduation rates and spending study

Increased Spending Reaps Benefits in Graduation Levels
In districts that substantially increased education spending as the result of court orders, low-income children were significantly more likely to graduate from high school, earn livable wages, and avoid poverty in adulthood. Between 1971 and 2010, supreme courts in 28 states responded to large gaps between richer and poorer districts by reforming school-finance systems. Although the changes had limited consequences for higher-income children, for low-income students who spent all 12 years of school in districts that increased spending by 20 percent, graduation rates rose 23 percentage points.
