My recent post on special education (SPED) had one education scholar emailing me to point out that a perverse financial incentive exists to place students in special education. I agree with that, though it doesn't discredit the influence that special education advocacy and parental groups have exerted on the issue (which others like Wade Horn and Douglas Tynan have also acknowledged).
But I'm also intrigued by some other factors that may be influencing the rise in SPED costs. I'm referring to research in Massachusetts a few years ago which found that cost increases in that state were less a factor of district policy or practice (e.g., inaccurate over identification of SPED students) and more a case of increasing numbers of students with significant special needs requiring more costly service. Specifically, researchers found several major underlying causes of rising SPED costs. One was changes in medical practice that now enable increasing survival rates for premature babies (many, unfortunately, with lifelong developmental and neurological problems); deinstitutionalization (more SPED children once served by state facilities are now served by school systems); and social/economic factors (more children exposed to child abuse, neglect, drug use, and dysfunctional family environments). So it's not just perverse financial incentives or influential SPED advocacy groups that are contributing to rising costs. Given these findings, it may be both our good intentions and our bad ones.
