"Early studies comparing Catholic and public schools often were discounted by critics who argued the differences were a result of selectivity bias, claiming the Catholic schools leave the worst-performing and worst-behaved students in public schools. But when Derek Neal at the University of Chicago analyzed U.S. Department of Education data and took that potential bias into account, he found the Catholic school advantage was still evident, with Catholic schools producing the following long-run results and lifetime advantages:"

Just exactly how can you take into account the "potential bias" of the cherry picking of students? How can you eliminate the bias inherent in a childhood in which your parents care about your education? How can you norm for parents intelligent enough to find solutions to educational problems? I'm glad the Catholics do a good job for the students they take, but I see no valid way to compare them to the public educational system which must take all students (including the incredibly expensive special education students).
