Something's broken with the buses. The Globe notes that most of the buses in Boston's system fill less than a quarter of the bus, some as low as one or two students. Why drop or dramatically alter the busing scheme and spend half the $79 million (9% of the city's budget) on private tutors at schools that aren't performing up to par, increasing school days if need be? $40 million buys a lot of private, highly qualified tutors.
Considering some of these buses are shipping next to no students halfway across the city, that sounds like a way better way to both make sure kids are getting a quality education and making sure the city is spending money efficiently. Otherwise, there's layoffs and everyone loses, including those getting bused, as the bus system suddenly takes up 10-15% of the school budget because of the cuts.
I honestly doubt sending the kids across the city would dramatically improve the education they receive; the very fact that these kids are willing to go that far, and have parents willing to go through that extra mile, suggests that they're generally good students already. 'Bad schools' are schools that just lose more students - students that can't or won't do homework or study because of home life or don't have the tools to learn what they didn't learn whilst in class (everyone has their own pace). Finding ways to get at them, teach them what they need, preferably during school hours, is the way to salvation at schools. That's not going to come from a bus. It's going to come from more hours in school, with guided study sessions that include personal tutoring if need be, so students are learning what they need, when they need it.
