Jonathan Mulhern, associate head of school of Boston Latin School, is leaving to become a middle-school principal in Canton.
Head of School Rachel Skerritt had announced her resignation in March.
Mulhern had been a BLS administrator since 2011, and associate head of school since 2018. Before that, he taught English.
In a statement, Canton Superintendent Derek Folan, said he is thrilled to have Mulhern:
For the last decade, he has proven to be a highly effective leader for middle grades, facilitating best instructional practices to promote strong student achievement, educational equity, and effective social and emotional growth.
In 2016, after then BLS Headmaster Lynne Mooney Teta resigned, an assistant headmaster resigned as well.
