Story by Adam Taylor and Lee Williams focuses on 11-year-old David Moore, a success story at Nativity Preparatory School in Wilmington, Del. Created by the Oblates of St. Francis de Sales two years ago, Nativity Prep is a private Catholic middle school for boys from households earning less than $28,000 a year. Of the 27 students at Nativity, 24 of them are black. Classes are held from 8 a.m. to 3 p.m., with mandatory sports from 3 to 5 p.m. Students go home for two hours, but return at 7 p.m. for a mandatory two-hour study hall. They take field trips on Saturdays. In July, the students attend mandatory academic camp at DeSales University, where they are immersed in a variety of classes and activities. According to school director Richard DiLillio, the aim at Nativity is to save children, one at a time.
