School Notes

Located in Fullerton, California, Rosary Academy is a private, four-year secondary Catholic school for girls.
Rosary was founded in September 1965 under the auspices of the Archdiocese of Los Angeles and administered by the Sisters of St. Joseph of Orange.
In 1976, with the establishment of the Diocese of Orange, Rosary is now under the jurisdiction of the Bishop of Orange.
Mission: As a college preparatory diocesan Catholic high school, Rosary Academy empowers the mind, body, and spirit of each young woman in a transformative educational experience. Guided by the Blessed Mother, Rosary Academy embraces and challenges its students with an innovative instructional curriculum to achieve academic success and ignite the call to serve the dear neighbor without distinction.

School Mascot: Royals (crown)

The Rosary community includes faculty, staff, administration, students, alumnae and families. We believe in the value of the family unit as the primary educational environment for our students; therefore, we work to assist the family in this endeavor. We strive to provide a faith community which accepts Jesus Christ as the Way to respond to one`s neighbor, the Truth to be communicated, and the Life to be shared. We uphold the dignity and uniqueness of each individual within the community experience. We endeavor to provide guidance for her journey of faith and opportunities for her growth and development as a daughter of God.
Rosary Academy offers a diversified college preparatory curriculum complemented by an extensive co-curricular program. We challenge each student to acquire and refine the skills necessary for a fulfilled, well-balanced life. The faculty and staff are strongly committed to developing in our students academic excellence and technological competence in all areas. We seek to cultivate leadership skills, initiative, personal accountability, and an increased sense of self-worth.
The goal of the Rosary community is to empower each student to become a woman of faith and a citizen who is knowledgeable, creative, ethical, and responsible. In the face of our multi-cultural constantly changing world, we call upon each young woman to become a contributing member of society and a lifelong learner who appreciates the value of both culture and creation. We are committed to helping each young woman recognize herself as a positive force within the greater human society.
