The present Livonia High School was established in Livonia in 1915. The following year, 1916, this school was combined to also include all of the students from Valverda and Dreyfus schools. The present Livonia High building was built in 1936. It was originally a two-story brick building. The second floor was lost to a fire in 1971. During the 1990/1991 school year, Livonia High was scheduled to be closed down as part of a parish wide school consolidation plan that resulted in the establishment of Pointe Coupee Central High School. Because parents in Livonia and the surrounding area protested the closure, Livonia High School remained open; however, other Pointe Coupee Parish Schools closed and students transferred to Pointe CoupeeCentral High School. The school serves approximately 1000 students living in the southern region of Pointe Coupee Parish. In 2011, the school became home to the United States Air Force JROTC detachment LA-935. This detachment had previously been headquartered at nearby Pointe Coupee Central High School. The JROTC program was discontinued after the 2014 school year.
