Immaculata, a four year, private, coeducational Catholic High School, is located on Mountain Avenue adjacent to Route 22 in Somerville, New Jersey.

Founded in 1962 by Monsignor Eugene B. Kelly, the school was built by the parishioners of Immaculate Conception Parish. Immaculata serves the needs of the populations of Somerset, Hunterdon, Middlesex and Warren counties in New Jersey.

The high school is accredited by the Middle States Association and the New Jersey Department of Education. It is an educational component of the Diocese of Metuchen. In 1998, Immaculata was recognized by the U.S. Department of Education in the Blue Ribbon Schools Program as a recognized school of excellence. The school curriculum is designed primarily as a college preparatory. Student scheduling allows non-college bound students to succeed on their own level. There is a full complement of honors classes, and advanced placement classes in English, History, Calculus, Physics, and Chemistry with the possibility of taking Advanced Placement Examinations. A wide variety of sports and extracurricular activities enhances the academic program.

The school operates as a legal corporation with the Bishop of Metuchen as the President of the Board. It is administered by a sister-principal under the guidance of the pastor-director. The faculty is composed of the Sisters, Servants of the Immaculate Heart of Mary, lay personnel and a diocesan priest chaplain who is part-time.

For forty-two years, Immaculata has served the church and the community by educating young adults to be responsible citizens eager to live their Catholic faith and serve others as they work towards peace and justice.
