COLUMBUS, Ohio -- Charter school funding in Ohio will creep to nearly $1 billion a year, under Gov. John Kasich's schools budget, estimates released today show.

If more students decide to attend charters next school year, that $990 million total could top the billion dollar mark.

Estimates by the Legislative Service Commission, the non-partisan research arm of state government, also showed other key details today of how charter funding would change if Kasich's plan is approved by the legislature.

Charter schools are privately-run, but they are public schools open to all students and funded by the state.

In addition to showing changes in aid to charters,

the new estimates show how state aid to school districts would change, once the state deducts money for students from each district who choose to attend charter schools.

See below for an explanation of how those deductions work.

Here are some highlights:

* The state will pay charter schools $34.5 million more in the 2016-17 school year than this school year for daily operations, even if charter enrollment stays the same.

* That's about $279 more for each of the 123,000 charter school students in 2016-17 than today -- a 3.7 percent increase.

* Some of that is from the $100 increase in the base aid per charter student in 2014-15, which increases to $200 more in 2016-17.

* The state will also pay charters another $9.3 million a year to help pay for facilities. Kasich wants to give $100 more to all "brick-and-mortar" charter schools per student for facilities, but not to online schools.

* No district that was slated to receive a significant increase under Kasich's earlier budget estimates will end up losing money after the charter school dollars are deducted.

That's a significant change from Kasich's last budget in 2013, when districts guaranteed of seeing no losses ended up in the hole once charter money was deducted.

* But many districts will see funding gains dwindle after charter deductions.

The Cleveland school district, for example, was listed in Kasich's early budget estimates as gaining $5.6 million in state aid by 2016-17. After increased dollars are deducted for charter school students -- again, assuming no enrollment changes -- that total drops to a gain of $488,000.

* Other districts that were slated to lose state aid in Kasich's early estimates will end up further behind after the deductions. Counting charter deductions, Northeast Ohio suburban districts make up 10 of Ohio's 11th largest percentage losers.

They are: Mayfield, Brecksville-Broadview-Heights, Independence, Westlake, Beachwood, Kenston, Nordonia Hills, Orange, Chagrin Falls and Strongsville.

To see your district's gains or losses under Kasich's proposal see the chart below. Note that these totals include money from Kasich's aid formula, deductions for charter school students and adjustments for reduced state reimbursement for the state's elimination of the Tangible Personal Property and utilities taxes -- business taxes that districts once counted on.

Here's what we mean by a charter school deduction: Ohio plans its state aid by district depending on how many students live in the district. The first budget estimates list how much money would go to the students from that district's area.

But since some students attend charter schools, the state sends part of that money to the charter school the student attends. That money is deducted from the first calculation. The district receives what's left.

How will state aid to school districts change under Gov. Kasich's budget, after charter school deductions?

Note: Student count is based on this ongoing school year. The calculations assume no change in future years so it can show the effect of the funding plans itself, independent of whether enrollment goes up or down. Partial students are from students who only attend a charter part of the year.
