The Boston School Committee voted 5-2 on Wednesday night to offer the position of superintendent of the Boston Public Schools to Dr. Brenda Cassellius. Cassellius recently stepped down as Commissioner of Education for the state of Minnesota. She still must formally accept the offer for the position, then negotiate the conditions of her employment, including salary, and a starting date. The school committee voted during a meeting after publicly debating the three finalist candidates. The two other finalists were Dr. Oscar Santos, Head of School for Cathedral 7-12 High School in Boston; and Marie Izquierdo, Chief Academic Officer for Miami-Dade County Public Schools in Florida.
