History

The school attracts students from over 30 parochial, private, and public schools in Monmouth County and Middlesex County. The school maintained an average enrollment of 435 students in grades nine through twelve. Mater Dei was a part of St. Mary Parish and later operated under the supervision of the Roman Catholic Diocese of Trenton. The school was accredited by the Middle State Association of Colleges and Schools Commission on Elementary and Secondary Schools and was a member of the National Catholic Educational Association (NCEA). The virtual learning program began in 2005 and ended in 2010. Virtual learning classes included all levels, including Advanced Placement, in Math, Foreign Languages (Latin, Italian, and Chinese) as well as History. In February 2015, the pastor of St. Mary Parish announced that the school would be closing at the end of the 2014-15 school year, in the wake of chronic fiscal deficits. A few days after the announcement, it was disclosed that the Parish Finance Council had agreed to a two-month extension in order to raise the $1 million needed to remain open. Through the Seraph's Fund, and efforts by the student body, $1 million was raised in a two-month span and the school was able to open for the 2015-16 school year. As of the 2021–22 school year, the school had an enrollment of 223 students and 21.4 classroom teachers (on an FTE basis), for a student–teacher ratio of 10.4:1.
