Guided by Father Placide Dobyns, Annunciation Catholic School was founded in September 1939. The first school was housed in the original Annunciation church building. Sister Caroline from the Benedictine Sisters of San Antonio was the first principal of the school. Father Hubert Bordenave led the construction of the present school building in 1956 and Bordenave Hall in 1980. School Sisters of Notre Dame provided teachers from 1948-1982 with Sister Herman Marie as their last principal. The Mary Paduda Early Education Center was dedicated in 1996. The Teresian Sisters were the last religious order serving the school, with Sister Amelia Ibarra as principal from 2001-2006. Annunciation Catholic School is the only Catholic school in Washington Parish, Louisiana, and is located at 511 Avenue C, in the center of Bogalusa. The school is approved by the State of Louisiana and the Archdiocese of New Orleans and is accredited by Cognia. The school currently serves 100 students in grades prekindergarten 3 through seven. 

   Despite its small student population, Annunciation offers classes, programs, activities, and clubs offered by other schools in the local area. The ACS curriculum is based upon and exceeds the State of Louisiana’s Comprehensive Curriculum and meets all Bulletin 741 standards for nonpublic schools. Small class sizes ensure individual attention and promote friendships and a nurturing and positive classroom and school culture.

    Annunciation Catholic School enjoys a reputation throughout the community as a school of excellence. For 81 years, Annunciation has been synonymous with achievement, service, and devotion to Christ. Graduates of the school excel in public and private institutions within both Washington and St. Tammany parishes.

Students and their families report that the foundation received at Annunciation was an integral part of the students’ success. It is impressed upon ACS students to develop “the total package," from the state of their school uniform to their willingness to serve others. It is no wonder that ACS students are recognized for their high moral standards, academic readiness, and dedication to service.

Annunciation Catholic School prepares students of all faiths for the challenges of an ever-changing world by providing opportunities for academic excellence, character development, and humble service in a Catholic, Christ-centered environment.

Annunciation Catholic School will foster the spiritual, intellectual, and social development of the whole child.
We seek to develop within our students a personal desire for life-long learning, faith enrichment, social justice, and a profound contribution to society.

Annunciation Catholic School being a part of the Archdiocese of New Orleans and the universal Catholic Church based on the example of Jesus Christ welcomes and admits students of any race, color, national, and ethnic origin to all the rights, privileges, programs, and activities. National and ethnic origins are not a basis in the administration of educational policies, admission policies, athletic, or other school-administered programs.

In order to be identified as a Catholic student, the candidate is to have received a valid Catholic baptism, or all of the Sacraments of Initiation through participation in a Children's Rite of Christian Initiation. In order to be considered a Catholic student, the person must be attending, on a regular basis, Sunday Mass in a Catholic Church. Having a sacramental certificate is not enough to be considered “Catholic.” The student must be participating in Catholic worship and being formed as a Catholic. Only those who have been mentioned above are to be considered for Catholic tuition and/or reduced tuition rates. Families of students who do not meet these requirements are not to apply for reduced tuition.

To be in this category, the student and family should be baptized and attending Catholic worship for a least a year prior to or after receiving the sacrament(s). In other words a students is not to receive Catholic baptism just to receive the benefit of Catholic tuition rates.
