Students like Delano Coffy are at the heart of brewing political fights and court battles over whether public dollars should go to school vouchers to help make private schools more affordable.

He was failing in his neighborhood public elementary school in Indianapolis until his mother enrolled him in a Roman Catholic school. Heather Coffy has scraped by for years to pay the tuition for Delano, now 16 and in a Catholic high school, and his two younger siblings, who attend the same Catholic elementary school as their brother did. She's getting help today from a voucher program, passed last year at the urging of GOP Gov. Mitch Daniels, that allows her to use state money for her children's education.

"I can't even tell you how easy I can breathe now knowing that for at least for this year my kids can stay at the school," said the single mother, who filed a petition in court in support of the law. The state Supreme Court is hearing a challenge to the law, which provides vouchers worth on average more than $4,000 a year to low- and middle-income families. A family of four making about $60,000 a year qualifies.

For all the arguments in favor of vouchers, there are opponents who say vouchers erode public schools by taking away money, violate the separation of church and state by giving public dollars to religious-based private schools, and aren't a proven way to improve test scores.
