Catholic elementary schools in Nassau County

About twenty-eight Catholic elementary schools teach approximately 10,360 students in Nassau County, according to the 2013 Official Catholic Directory. Most of these schools are parish-based.  Five are regional, that is, nearby parishes support a school together or are listed as sending their students to that school.  Each of the three "private" schools is unique.  The De La Salle School, Freeport, teaches only boys and only grades 5-8.  Holy Child Academy is an independent school with higher tuition.  The St. Martin de Porres school in Uniondale is somehow linked with neighboring parishes but controlled by the Marianist Province of Meribah.
