Pat Greenhouse / Boston Globe via Getty Images Share The Boston School Committee has extended Superintendent Brenda Cassellius' $311,000-a-year contract, calling her work proficient but not exceptional. The committee's 4-1 vote Wednesday night took place despite calls from activists and some members of the public to delay a decision until the city elects a new mayor. School Committee Vice Chair Michael O'Neill said waiting until then was not feasible under the terms of Cassellius' contract, which brought her to Boston from Minnesota two years ago.
