A new accreditation report criticizing Belmont High School’s curriculum and safety triggered outrage from the school district’s interim superintendent, who, in a letter to the community last week, called the report riddled with “caricatures, exaggerations, and outright falsehoods.”

The district received the report from the New England Association of Schools and Colleges toward the end of last month, said Thomas S. Kingston, who started his interim role in Belmont last year.
