School lunch programs are largely federal, aren't they? The school itself isn't paying most (or any) of the bill, and I'm not aware of any link between socioeconomic status and learning disabilities.[0] Even if it did, does having a larger proportion of learning-disabled pupils negatively effect a school's funding?
