After the United States bishops declared the necessity for more Catholic schools, St. Augustine Church opened its parochial elementary school in September 1926. Under the direction of the Daughters of Mary and Joseph, the school originally had an enrollment of 123 students and only 4 classrooms. In 1938, a set of bungalows was added. In 1947, a new building of reinforced concrete was completed, with a second wings added in 1969, allowing enrollment of 700 student with 2 classes for each grade.
The sound leadership of the Daughters of Mary and Joseph led the school to make changes that would help its students. As enrollment decreased in the early 70's, and costs rose with the rising number of lay faculty members, the school decreased to a single class per grade level. This allowed for the conversion of some classrooms into various types of specialized classrooms, such as an art room, a science laboratory, and 2 computer laboratories. One room was made available to the parish's religious education program.
In the 1980's, the parish pastor, Monsignor Ian Holland, looked to the school's future financial stability. With decreases in enrollment occurring in most Catholic schools, the pastor discussed the necessity of ensuring the school's presence in the face of declining student tuition. He established a school endowment account by starting a parish collection on the third Sunday of each month.
A lay principal was first appointed in 1997. In response to the rising need for early childhood education, the school began renovating its first floor in 1998. The school now holds an early education program for ages 2 through 5 on its first floor. In spring 2005, due to the foresight and continuous involvement of the parent of alumni, the science laboratory received an extensive equipment upgrade. Between 2006 and 2008, major renovations were made to the school restrooms. A multi-purpose classroom allowed for small group reading classes, visual art classes, and performing arts classes. After Internet lines were upgraded, Wi-Fi access was routed throughout the school. The two computer labs were then consolidated, and additional portable devices were added to the program.
With an aim to promote the longevity of the school, the principal created a facilities team in 2015. Under their direction, a comprehensive master plan was developed to ensure the continuing mission of the school in the 21st century. In 2016, another upgrade in the digital infrastructure occurred, while implementing the Core Instructional Method/Practices into teaching methodologies. The school received an Archdiocesan C3 grant in 2017, making one-to-one digital devices available to all students. The school began implementation of global competency into its curriculum in 2018 by applying the United Nations Sustainable Development Goals 2030. In 2019, the school began using the ADLA Finland Cohort's recommendations for classroom instruction.
In March 2019, the school went into quarantine because of the CoVid19 pandemic, with students learning by using one-to-one devices in virtual classrooms. The school began using a hybrid model in March 2020 to accommodate all families. Unfortunately, the socio-economic conditions greatly impacted school enrollment. In January 2023, the school adapted to multi-age classrooms both to increase student learning and to maintain the financial viability of the school.
