News of Catholic school closures has become so commonplace over the past few decades that it's almost not news anymore. What was once a vibrant nationwide school system serving five million students a year has become a struggling sector serving fewer than half that number. Last week, the Archdiocese of Chicago announced its plan to close another five schools at the end of this year, citing declining enrollment and financial challenges. One of these schools has been serving students on Chicago's South Side for over 115 years. In Memphis, the diocese announced yesterday that all nine of its inner-city Jubilee Schools will close this year. It's long been clear that something has to change.
