Schools

Arlington school officials recently realized they made a critical error in calculating school enrollment rates as they prepared a final proposal for the redrawing of attendance boundaries in South Arlington, prompting the last-minute introduction of a new map to correct that snafu.

The School Board is gearing up for a final vote this week on boundary changes at eight elementary schools, which will conclude a lengthy, contentious process stretching over the better part of the last six months. Superintendent Patrick Murphy put forward what was meant to be a final proposal last month, but officials then tinkered with that map to better distribute students across the schools involved and reduce overcrowding.

(Updated at 9:50 a.m.) Many parents of Patrick Henry Elementary School students have expected, for years, that their community would move as one to Alice West Fleet Elementary when it opens next fall.

They believe Arlington school officials have repeatedly promised them as much over the years, as deliberations have progressed over the best way to build a new South Arlington elementary school, then shift Drew Model School’s Montessori program to Henry’s old building. That’s why so many Henry parents are now furious that Superintendent Patrick Murphy’s proposal for a redrawing of school boundaries would send more than a fifth of current Henry students to schools other than Fleet.
