The Boston School Committee Wednesday night selected former Minnesota education commissioner Brenda Cassellius as the system’s next superintendent, believing she was the best candidate poised to repair bruised relationships with the community and boost student achievement.

Five committee members voted for Cassellius, including Michael Loconto, the chair, saying the choice came down to experience versus seasoning.

“Brenda Cassellius is the right choice for the leader of the BPS,’’ he said.
