Immaculate Heart Academy

Immaculate Heart Academy (IHA) is an all-girls college preparatory private Roman Catholic high school located in Washington Township, in Bergen County, in the U.S. state of New Jersey.

Immaculate Heart Academy has been accredited by the Commission on Secondary Schools of the Middle States Association of Colleges and Schools since 1971 and is accredited until January 2034. The school is also accredited by the New Jersey Association of Independent Schools.

As of the 2023–24 school year, the school had an enrollment of 638 students and 62.5 classroom teachers (on an FTE basis), for a student–teacher ratio of 10.2:1.

The school colors are blue and white, and the school's athletes are known as the Blue Eagles.

The school was founded in 1960 by the Sisters of St. Joseph of Peace as the first regional high school for girls in the Roman Catholic Archdiocese of Newark. From 1990 to 2008, administration shifted to the Apostles of the Sacred Heart of Jesus.

The school opened in 1960 with 180 students in ninth grade in an interim site at a church in Paramus, having received approval to build a Permanent facility on almost 11 acres (4.5 ha) in Washington Township that would accommodate a maximum enrollment of one thousand students.

For the 1996–97 school year, Immaculate Heart Academy was recognized with the National Blue Ribbon Award of Excellence from the United States Department of Education, the highest honor that an American school can achieve.

The Immaculate Heart Academy Consultative Board began its duties on July 1, 2009. In prior years, a Finance Committee had been established and was effectively providing financial advice and direction to the school.
