Building upon my last post, I began to discover that the concept of Individualized Education Programs had been around for years, but it is only within the last few years that the schools have really done anything for students besides the children who are usually thrown in the self contained class and the gifted and talented group. Normally, you find a theme where the school becomes concerned if the child didn't pass the tests that the school is complaining that they have to teach towards in order for the school to receive its funding.
On the surface, it looks like they are dumbing down the curriculum by forcing everyone to learn "what is 2+2", but then you notice that there is an increase in number of children who get extra time on tests and "mainstreaming" where the child is considered smart enough to stay in the regular classroom, but is taken out so that they are given additional one-on-one assistance. This is not altruistically done and certainly there are still many parents out there that are having to fight with the school to give them help, such as if they are autistic but can learn in a regular classroom as long as they have an assistant with them instead of shuffling them off to the self-contained class like they would have done in the past. Now, the schools have a prod up the backside that forces them to help other children since their performance on those tests is directly tied with their funding.
So, while the system isn't perfect, I think a lot of the complaints from schools are posturing because they ultimately hate having to hire the extra people needed to pull this off.
