St. Agnes Academic High School, a private Catholic high and independent of St. Fidelis parish, has been operating for over one hundred years. In its early years, it was very briefly co-educational, but is now restricted to girls. It is owned and still staffed by the Dominican Sisters of Amityville, assisted by lay men and women. For many years, Reverend Mother Agatha, O.P., was superior and principal of St. Agnes High School. The Dominican Sisters reside in Saint Agnes Convent as well as the Harbor of Grace Convent, which was the original convent for this community. In June 2018, The Harbor of Grace Convent will permanently close, since the Diocese of Brooklyn wishes to reclaim the building. The Harbor of Grace, first opened in the early 1970s, with Sr. Julianne (Nora Daniel) Connolly, O.P. being one of its pioneers. Sister Julianne has lived there for its entire history. St. Agnes Convent, the last of the Dominican Convents in College Point, will close in 2019.
