Shawn Lee is matter-of-fact when he compares traditional public school budgets to that of RBA Public Charter School.

Lee started teaching at the Mankato charter, formerly called Riverbend Academy, eight years ago. In that time, he’s watched traditional school districts slash millions from their budgets, lay off dozens of teachers and discontinue student programs. He knows a handful of area schools are set to close their doors at the end of the school year while four-day weeks and cuts to electives have become standard fare for discussion in school board rooms.

But Lee said it’s a different story for charter schools.

“We don’t really (cut) anything student related,” Lee said.

Charter schools are funded essentially the same way as traditional schools. Funding is based on enrollment, with each student accounting for roughly $5,200 in state aid (in reality, students are weighted on several academic and economic factors to determine state aid).

And like traditional districts, charters are subject to the same set of ever-increasing fixed costs — lease payments, transportation and insurance costs — and draw from the same pool of state aid.

The difference is, charter schools are excluded by law from holding referendums and levying for more tax support.

“We have to live off our budget,” said Don Johannsen, RBA’s program adviser. “It is what it is.”

Charter schools generally eschew traditional administrative positions, usually in favor of a collaborative system where teachers make decisions together. Charter teachers are not unionized ( “That helps,” Lee said) and staffing is based purely on enrollment (“If we have a waiting list, we hire a new adviser,” Lee said.)

Nearly all traditional public schools spend well upward of 75 percent of their general fund budget on staff costs. Doug Thomas, director of the charter-school oversight organization EdVisions Schools, said most charter budgets allocate about 65 percent to staff costs.

Thomas, whose organization lends support to more than 50 charters nationwide, adds that none of the 10 charters he oversees in Minnesota — including Minnesota New Country and RBA — are struggling financially.

“They don’t have that bureaucracy surrounding them,” Thomas said. “Charter schools are so directly managed.”

At RBA, the entire staff works on the budget together. Johannsen said the process starts by allocating all fixed costs and program expenditures and then “seeing what’s leftover for salaries.” A couple of years ago, teachers accepted a pay cut. Last year, wages were frozen and this year, raises are highly doubtful.

But the fiscal diligence paid dividends last fall when RBA received a School Finance Award, which is given to districts that comply with state accounting regulations and preserve recommended fund reserves.

“We take the budget, sit down and make it work,” said Johannsen, who added that the percentage of charters receiving finance awards last year (33) was nearly double that of traditional districts. “Charter schools know they’re being scrutinized. They have to be accountable.”
