(19)A Catholic high school in Chicago ensured its financial survival by having students help pay their tuition by working one day a week in clerical jobs at downtown offices. This was a new idea in the US secondary education. New ideas are not necessarily a good thing, because they often fail.(20)But the Cristo Rey Jesuit High School has grown to 25 schools in 17 states. The creator was an educational missionary named John P. Foley who started the original school in 1996. To some, it seemed to be a foolish venture. Catholic schools were dying in the nation’s urban neighborhoods. There was no way to pay for them. But Richard Murray, a management consultant Foley knew, had an inspiration. What if Foley divided the student body into teams of four and assigned each team to an office job in the city? Each student would work one day a week. Their combined salaries could guarantee the school’s future. More than 90 percent of the students at the original Cristo Rey school were from low-income families. Few had been subjected to the pressures of big-city offices. But they received proper training for their clerical assignments.(21)As the experiment proceeded, they realized the writing, reading and math skills they were learning in school were relevant to their new jobs—and their work experience would help them find jobs to pay their way through college. Foley urged other cities to adopt the unorthodox Cristo Rey approach. A network of new schools began to grow. Today, it has 325 students who work one full day per week at law firms, banks, hospitals, universities and other professional corporate partners and are in the classroom the other four days.
