Since 1985, school attendance zones have been configured partly to help the district meet its "60 percent guideline." Although all schools are currently in compliance with the guideline, the district has not always followed it strictly, and some who see a link between busing and achievement would just as soon see it modified or discontinued.
The school district provides busing for children who live at least 1.5 miles from their attendance-area schools or who would have to cross a major street to reach school on foot.
Almost nowhere in 674 pages does he, say, pass judgment on anyone or anything; although I think he'd say busing was a failure, I couldn't produce a passage in the book to prove it.
And he breaks from the narrative five times to profile, vividly, the major public figures involved in busing, which helps make Common Ground work as a multi-layered portrait of Boston as a whole.
