In 1929, San Felipe Independent School District (I.S.D.) formed; one of the District's first decisions was to establish a high school. Residents voted unanimously for a bond for the institution. Building was completed at the corner of Plaza and Garza Streets and the new high school opened in December 1930. The new campus hosted a full range of grades, with secondary students attending school in the main building and grades six through eight housed in a posterior structure. The high school offered traditional subjects, competitive sports and a wide variety of fine arts. The colors for the Mighty Mustangs of San Felipe High School were purple and gold. In 1932, the School held its first commencement exercises for a graduating class of seven students.
San Felipe High School was known for its caring teachers, who along with administrators helped to create a close-knit community. The School also had high parental involvement. This encouraging atmosphere shaped students, aiding them in achieving later career and life success. Additionally, the School served as a focal point for the community. It held adult education classes and citizenship classes, functioned as a voting place, and has housed families displaced by floods.In 1971, San Felipe High School closed when San Felipe I.S.D. consolidated with Del Rio I.S.D. Memory of the institution has been kept alive by the generations of students who attended and by the School's alumni association a rarity for a school that no longer exists. Today, San Felipe High School is remembered for being a cornerstone in the San Felipe community for over 40 years. (2009)
