At M.S. 126 [in Williamsburg], despite the librarian’s dismay, the principal, Rosemary Ochoa, has worked out what she considers a viable plan with the Williamsburg Charter High School and its two small spinoffs, which also occupy the building. The charters get the library for most of the day, and Ms. Tecza is expected to travel to individual classrooms to teach the public students library skills.

The City’s space planning for schools remains a nightmare, with underutilized schools (PS 84) blocks away from overcrowded ones (MS 126). And while the trend towards charter schools fills up unused space in many local schools, it does nothing to the improve the education of the host schools.
