The school began with four students in 1910. Initially for only white male orphans, the school expanded in the 1960s and 70s to include girls, racial minorities, and "social orphans"—those with impoverished parents. About 2,000 students attended the school in 2020. Admission is restricted to low-income individuals aged 4–15 without intellectual or behavioral problems. Students live in group homes of uniform gender and similar age, with set schedules for elementary, middle, and high school students. The school has Judeo-Christian elements, but is officially non-sectarian.
