Federal law first insisted in 1975 that public schools educate disabled students. Since then, the portion of students receiving special education services has increased 64%. Today, 13.5% of all public school students have been diagnosed with a disability. Special education, it turns out, is no longer particularly special at all.
Taxpayers pay a substantial price for the growth in special education. In New York state, for instance, in 2007, the average special education student cost $14,413 more to educate than a regular-enrollment student.
What has produced such rapid growth in the percentage of American students identified as disabled? Don’t worry–it’s not “something in the water.”
Better means of identification explain part of special education’s expansion. However, a growing body of research points to a less benign cause: Schools see a financial incentive to designate low-achieving students as disabled, while they may not actually be disabled at all.
