I know exactly what you mean. A good friend was threatened to have her child taken from the home if she didn't classify him as learning disabled.
The effort to 'classify' is driven by the fact that the child's academic scores are NOT counted when the school is evaluated for meeting the standards.
Another angle I was unaware of. Thanks. I knew they got more money for special ed kids up front. Heard in Boston schools they have nearly a third of the boys classified as having learning disabilities.
