Abstract: What makes a high school successful? Coleman, a sociologist a t the University of Chicago, and Hoffer, a research associate at Northern Illinois University's Public Opinion Laboratory, conducted a fouryear study of 1,015 private and public high schools. They conclude that successful high schools result from strong communities reinforcing teachers' efforts. The authors distinguish between two types of school communities. "Functional communities" are those where the school's goals mesh with the values of the surrounding neighborhood. During the first half of the century, because parents and teachers both taught values "which place [dl importance upon learning" (hard work, respect for teachers), even children from lower-class families mastered the skills needed to better themselves. Many "functional communities" died during the 1960s, as school consolidation and busing created huge high schools that had little to do with their surrounding neighborhoods. Faced with public schools that were increasingly disorderly and bureaucratic, a growing number of parents placed their children in schools tied to "value communities," whose common bond is a set of values endorsed by the parents of the children enrolled in them. These schools range from fundamentalist Christian academies to such selective public schools as New York's Stuyvesant High and Walnut Hills High in Cincinnati. Unlike most private and public schools in the 1980s, Catholic high schools are still part of functional communities; values learned in school are shared by both home and church. Parents are more involved in Catholic high schools than in public schools; 17 percent more parents of Catholic high school students attended a parent-teacher conference and 19 percent more parents did volunteer work for their school than did public school parents. Fifty-three percent of public high school principals said that parents "lack in te res t in s tudents ' progress," compared to only seven percent of Catholic high school principals. Because parents support teachers who make students work hard, Catholic high schools outperform public high schools and match other private schools in learning, even though Catholic schools pay their teachers less. Students in Catholic high schools learn three grades' worth of reading and mathematics in two years; public high school students learn two grades' worth in two years. In part, the authors attribute Catholic high schools' success to "relative inflexibility" which "has been able to withstand the curriculum watering-down . . . that occurred in American [public] high schools in the 1970s." Students in Catholic high schools are also more dutiful than those in comparable institutions; 49 percent of Catholic high school sophomores had perfect attendance records compared to 34 percent of other high school students. While 15 percent of public school sophomores and 12 percent of other private school sophomores later dropped out, only three percent of Catholic high school sophomores dropped out by their senior year. The authors are not optimistic about transforming public schools. They conclude that using tax credits to create private schools affiliated with a factory or other workplace probably would be the best way to restore "functional communities." These schools, similar to laboratory schools linked to universities, would be "the next step in a social evolution" that has replaced the neighborhood with "formal organizations" as the center of most American lives.
