St. Ann’s Academy, a private Catholic elementary and middle school that has been part of its Northwest Washington community for decades, will close at the end of this academic year because of declining enrollment and a large budget gap.

“Unfortunately, St. Ann’s parish can no longer support its school mission and assume or guarantee the school’s growing deficit,” Reverend Msgr. Godfrey Mosley, the pastor of St. Ann’s Church, wrote in a March 6 letter to parents.

Enrollment has dropped from 220 students in 2009 to 139 students this year, according to the letter. Fundraising and $200,000 in aid from the archdiocese was not enough to close the budget gap, Mosley wrote.

St. Ann’s is prominently located on Wisconsin Avenue next to Janney Elementary and the newly renovated Tenleytown Library. Mosley’s letter offers no indication of what might become of the school building. A spokeswoman for the Archdiocese of Washington said conversations so far had focused on doing what is best for the children at St. Ann’s, and there is “no dialogue about the future of the building at this time.”
