A recent Atlantic Cities look at school performance in Washington, DC, helps illustrate why school assignment in Boston is such a politically thorny issue to tackle.

DC recently opened a vault of data on school performance and other attributes, to help parents navigate that city’s choice-heavy school selection process. The Atlantic notes that the highest-performing schools are located in the city’s northwest quadrant, where its wealthiest families live. But the correlation isn’t just about wealth or race, the magazine argues — it’s also about travel patterns. There’s a strong correlation between DC public school performance and walkability.

The schools excelling in the DC public system are the ones kids can walk down the street to; the poorest performing schools are also the ones that students have to spend the most time, and effort, commuting to. There’s no such correlation on the public charter school side, partly because high-performing charters are drawing students from across the city, and partly because real estate values (which also rise and fall with walkability and transit access) dictate where charters can open.

The Atlantic doesn’t interpret the data as saying walkability drives student achievement. Instead, it takes the data as another illustration of inequality in DC. In doing so, the magazine hints at why school assignment and performance — the hottest issue in Boston’s mayoral race, assuming we find out whether we’re ever going to have one — is such a tricky and divisive issue

Boston Mayor Tom Menino launched the city’s most recent overhaul of its school assignment process (one that came after years of false starts and stops) after a brutal round of Globe stories decrying the current busing-heavy system. In a particularly harsh editorial, the paper accused the city of purposefully maintaining a Byzantine choice system, a “whole buckling contraption … designed to make up for the fact that about half of Boston’s schools rank in the bottom fifth on statewide tests.” Menino’s opponent, City Councilor John Connolly, has made school improvement and walkable neighborhood schools the leading prongs of his upstart campaign.

Some old-line activists protested the School Committee’s recent vote on a new hybrid choice and walking plan, casting the new system as a back door to school resegregation. But a lukewarm Globe editorial endorsing the new system pointed to a larger problem — Boston doesn’t provide equal access to enough high-performing schools in enough neighborhoods. Busing came to Boston because of segregation and race-based school spending; it’s hanging around because of neighborhood inequality.
