From generous eligibility rules to a timid political climate, the state faces several "disincentives" that make it hard to rein in the spiraling cost of educating the disabled, Legislative Auditor Jim Nobles told legislators Wednesday.
"We do not find any easy answers or simple solutions to the complex issues involved with special education," Nobles said. "But we still strongly recommend that we keep trying to make improvements and modifications where we can, because even small steps sometimes are worth taking."
In the report, Nobles found that school districts statewide are hampered by state and federal funding shortfalls that have forced them to cover about a third of all special education costs by dipping into their general education funds. Schools districts' special ed tabs jumped 40 percent between 2000 and 2011.
Altogether, special education accounted for 20 percent of state education spending in 2011, up from 9.8 percent in 2000. Nobles urged the Minnesota Department of Education to find ways for districts to improve cost controls.
After adjusting for inflation, special education expenditures jumped by 38 percent in the past decade, reaching $1.8 billion this year. A recent Star Tribune examination of special education programs showed that students with major disabilities typically cost some districts more than $50,000 per year, or more than twice the state average, with annual expenditures topping $100,000 for some students.
Rep. Jerry Hertaus R-Greenfield, said $1.8 billion "is some really big money." He openly worried that districts could be forced to spend even more than they are now and asked if there is a way to limit the spending to, say, $1 million annually per student.
"A dollar cap ... would probably be seen as illegal," said Jody Hauer, who led the audit for Nobles' office, noting that state and federal law prohibit districts from denying services strictly on the basis of cost.
Nobles said the most obvious cause of higher expenses is the growing special education population in Minnesota, which climbed 11 percent in the past decade, reaching 111,794 K-12 students in 2011, according to the report.
