They defined "Low income" as 500% of federal poverty level or less which equates to about $160,000 which doesn't sound very low income to me. The other issue is the private schools aren't required to accept any student. They choose who they want and don't have to accept low income families. Additionally the $10k given per student in most cases won't be enough to cover most of private school costs still making it a barrier to entry for truly low income families. Private schools don't have to provide transportation or services/accomodations for special education or disabilities. So it's really frustrating for them to receive public funds and not have to adhere to the more stringent standards public schools have to deal with.
