Iowa participates in the National School Lunch Program, which is a federally funded program that assists schools and other agencies in providing nutritious lunches to children at reasonable prices. The program covers breakfast and lunch, and sometimes, snacks. There will be an application from the school that you must fill out to prove your children are eligible.

If you live in Des Moines, you may go directly to this page to see what the menu for school lunches is: http://dmschools.nutrislice.com/
If you do not live in Des Moines, you can call the school that you, or your child is planning on attending and ask what the school lunch menu is. Students may also bring their own lunch, and some high schools allow students at certain grade levels to leave campus for lunch. Just to be sure, you should find out the rules from your school. Some schools have websites where they show what students are having for lunch.
