Annually, school districts in Ohio create a Comprehensive Annual Financial Report (CAFR), an audited document that provides different views of costs, expenditures, and revenue. Olentangy's latest CAFR -- found here on the state auditor website -- provides a simply way to get beyond the spin and into true district expenses.
The administration and Olentangy for Kids have been touting the district's costs per pupil as if their number details the total cost of running district operations. But, the Ohio Deparment of Education figure being used does not include real costs that any business would consider in its financial reports; namely interest, depreciation, etc.
Using accrual-based accounting, district costs per pupil soar from the advertised $8,507 per pupil to the true cost of $11,111. Shocked?
Well, you shouldn't be. Note that, despite the spin coming out of the district and levy committee, you are taxed for both operating and capital expenses. 
Consider this contrived example: Ask the manager of the local Burger King what the cost is to produce one hamburger. He thinks, and then states (say) 50 cents. You question him on that number and he says that salaries, benefits, beef, bun, etc, total only 50 cents, as if there are no capital costs associated with his store. The manager has understated his costs, just as the district understates its costs.
Read the CAFR and learn the true cost of education in Olentangy, your taxes paid for it.
 The district is ranked 31st highest for bond millage rate out of the 614 districts in Ohio.
