Year 1942 when Sto. Rosario Primary School was established thru the effort of some elders of the barangay with the help of the municipal government.
It started classes during Pre-Japanese occupation and continue until it became Sto. Rosario Elementary School in 1972. The school has its guiding principles. Its vision is to promote equity, efficiency, effectiveness and excellence in education. Its mission is to provide total quality, Basic Education services to school pupils to transform them as functional citizens in literate, God fearing, productive, just humane society.
From some elder folk accounts, the school started first in a single classroom so they had used two other houses as classroom such as Mr. and Mrs. Teodoro Navarette and Mr. and Mrs. Leon Santos. These houses had been used for Grade I and Grade II classes. And the erected Gabaldon building were used for Grade III and Grade IV classes. Sometimes, Sto. Rosario chapel was used for some special situations, then.
