Stephen Dyer, a fellow with Innovation Ohio and former legislator, explains how the charter funding system in Ohio takes money away from students who are not in charters.

“It’s really easy to sit back and make esoteric arguments about how Ohio’s charter school funding system hurts kids who are not in charter schools. And there’s a recognition from leaders in the Ohio General Assembly that the funding system — which diverts state funding meant for a district to a charter — is a shell game that leave school districts with far less state revenue than the state says they need to effectively educate their students. This, in turn, forces school districts to use sometimes large segments of their locally raised revenue to make up the difference.

“But what does that mean for a kid attending a local public school district?

“As an example, I’m going to use a student in Columbus City Schools. Let’s assume he or she started first grade in the 2005-2006 school year, which would make this student a senior this year (by the way, I was first elected to the Ohio House in 2006. Wow, does this make me feel old!)

“Anyway, I looked at how much state funding this student lost each year of their career because charter schools receive so much more per pupil state funding than Columbus City Schools would have received for the same kids. (Looking at state funding reports here and doing addition and subtraction based on number of students in Columbus before and after charter students leave, as well as how much state funding comes to Columbus before and after charter students leave.)

“Yes, I know charters can’t raise local revenue. However, the legislature has chosen to not put its money where its school choice mouth is and create a separate fund to make charter schools whole. Instead, they make up a chunk of the local funding disparity by removing extra state funding from the local school district’s bottom line, forcing local property taxpayers to do their work for them.”

Check out his graphs and data.

So, for every student who began their Columbus City Schools career in 2005-2006, they have received $10,548 fewer in state revenue, with another $1,142 set to be lost this, their senior year (charter enrollment is so volatile, this figure could change substantially during the year). To give you a sense of scale, that amount equals about the amount of state funding these Columbus students received their first three years of school — in many ways the most important years.
