One of our big positions is that children of all socio-economic demographics are not eating well and that all children deserve access to healthy food at school. Many might have a long bus ride if they're in a rural community and travel a long way to school, or their families work long hours and they can't access food, or their families don't have the budget. There's a wide range of reasons that children can't access food during the school day.
The universal piece is to address all students. It's also that targeted and means-tested programs do not actually achieve the aims they set for themselves. They have a lot of stigma attached, which means that those the program is intended for tend to refuse to participate and the program is not as effective.
