Every weekday morning, three school vans roll into the SouthField neighborhood and drive down freshly paved, tree sapling-lined streets to pick up schoolchildren who live there.

Some students wait at the bus stop by the sparkling new apartment complex on Parkview Drive. Others get picked up farther down the road, near newly built homes on Thistle Lane. They are among the youngest residents of SouthField, the new community-in-the-making growing on a former naval base straddling Weymouth, Abington, and Rockland. Since SouthField has no school system of its own, the students attend school in Weymouth.
