Pierre Guidry, a native of Acadia, Nova Scotia and the first settler of Cecilia, acquired three tracts of land from Mrs. Joseph Alexander Declouet in 1791.

The community began as a small service center of sorts for the many landowners in outlying areas surrounding the Bayou Teche.

As trade and commerce grew within the small steamboat stop along the Bayou Teche, the need for a public school was clearly evident.

Headmistress of the first public, free tuition school in the community was under the supervision of Mrs. A. P. Lastrapes (the former Marie De La Croix) in the St. Joseph Chapel around 1893.

Continued growth in student enrollment spurred the construction of a two-story, four room wooden structure on land purchased by Mr. Joel Dupuis on the eastern bank of the Bayou Teche in preparation for the 1905-1906 session.

Due to increased enrollment on the main campus, several new facilities such as a Multi-Purpose complex, Girl's Gymnasium, Band Hall, softball stadium, and improvements to student parking were completed during the 2012-2013 school year.

As of March 2019, a modern football and soccer field, track, and stadium with new fieldhouse and concessions stands are under construction on the main campus.

A college preparatory curriculum is offered as the school stresses a personal approach to the education of the whole student through diverse academic, athletic, and co-curricular programs.
