Immaculate Conception School exists as a gift to God’s children, to prepare them to live a life with Jesus the Good Shepherd as their teacher and friend. Inspired by the Holy Spirit, and through the intercession of Mary, the school seeks to foster in each student spiritual growth, academic excellence and moral integrity.
Immaculate Conception Roman Catholic Church was established on Oct. 13, 1864, as a mission church attended, at different times, by pastors of parishes in High Bridge, Hampton, Lambertville and Flemington. The first church building was constructed in 1879 and was situated on Halstead Street in Clinton Town. On Nov. 14, 1947, Immaculate Conception became a parish church with the appointment of its first resident pastor.

The parish moved from Clinton Town to the Annandale section of Clinton Township in 1969. Our present house of worship, situated on St. Mary’s Hill, was dedicated on June 30, 1996.

In 1992 the Sisters of Jesus our Hope established the Sheepfold at Immaculate Conception Parish, which served children in three-year-old preschool, four-year-old preschool and kindergarten.

In August 1999, Bishop Breen approved the establishment of a parish grammar school at Immaculate Conception. Immaculate Conception School opened its doors in the Fall of 2001 to children entering three-year-old preschool through fourth grade. In the Fall of 2002, our new school building opened and now serves students in three-year-old preschool through eighth grade.
