Boston University has abruptly parted ways with Ari M. Betof, the head of Boston University Academy, a small private high school that it operates on its campus.
Betof was appointed to head the academy, a school of just under 200 students, in 2015.
In a statement Monday, BU said it had separated with Betof.
“The reason for the separation does not involve any current or former BUA student or other members of the BUA community,” said Colin Riley, a Boston University spokesman.
Riley declined to answer further questions about Betof’s departure, and the university would not provide the date of his termination.
As of Tuesday afternoon, he was still listed as head of school on the academy’s website. By the end of business on Tuesday, BU had announced on its website that Rosemary White, the academy’s assistant head of school, would be the interim leader, effective immediately.
In a statement provided by his lawyer, Betof said he disagreed with BU’s decision.
“It has been an honor to serve as the Head of School for Boston University Academy (‘BUA’), working with its enormously talented students and faculty,” Betof said. “I am proud of what we — together as a community — have accomplished. Whatever my disagreements with BU over the decision made, I will continue to cheer on the students of BUA and its faculty as they set the bar high and do amazing work.”
Betof was previously head of school at New Garden Friends School in Greensboro, N.C., and served on the board of directors of the Friends Council on Education, a national association of Quaker schools.
The academy was founded by BU in 1993. The university’s board of trustees oversees the academy, which features small class sizes, university-caliber teachers, and the opportunity to take classes with college students and for college credit.
The school charges nearly $45,000 a year in tuition and fees. About one-third of students receive need-based financial aid, according to the school’s website.
According to public records, Betof and his family lived in a Brookline apartment complex, not far from the university campus, that BU provides for its faculty and staff.
BU told parents Tuesday that it would begin a national search for a new leader with the expectation of having someone in place by summer 2019.Deirdre Fernandes can be reached at firstname.lastname@example.org. Follow her on Twitter @fernandesglobe.
