This story is part of the NPR reporting project “School Money,” a nationwide collaboration between NPR’s Ed Team and 20 member-station reporters exploring how states pay for their public schools and why many are failing to meet the needs of their most vulnerable students.

There's a nearly $15,000 gap in per student spending between the highest and lowest spending districts in the St. Louis area, according to a new analysis of school funding by NPR.

The analysis uses a cost of living index to calculate a national per student spending of almost $12,000 in 2013. The analysis applies that same formula to measure what individual districts are spending in relative dollars.

As with the rest of the country, the data show St. Louis has an uneven school funding landscape.

There are some obvious high points, the Clayton School District spent $19,681 per student, according the analysis. That’s compared to Clayton’s neighbor, St. Louis Public Schools, which spent $9,826 per student.
