School voucher programs need (at least) three key ingredients:
1. Multiple schools (don't roll your eyes, city dwellers, this one's a brick wall for many rural parents).
2. A system that makes private schools affordable for low-income parents. Choice isn't choice if it's only the rich who get to choose.
3. And transparency, so that a child's caregiver can review the options and make an informed choice.
This story is about that last ingredient.
