The Sisters of the Blessed Sacrament will close Xavier Prep at the end of the school year.
They ran the school for 98 years.
Xavier Prep says it will work with the Archdiocese of New Orleans to help all students transition to new schools as needed.
The Archdiocese says it offered financial resources to the school but the Sisters declined the offer.
Xavier Prep alumni are organizing a meeting Saturday morning to discuss ways to keep the school open.
The meeting is at 10:00 a.m. at Dr. Martin Luther King Charter School on Caffin Avenue.
