Mount Barker Public School was officially opened on Friday, September the 14th 1877. It was located on Adelaide Rd and had an enrolment of 163 students on its opening day.

Due to the ever growing enrolments a new school was built on Dumas Street. This was a very long process but building was finally completed on November the 1st, 1965. It was officially opened on Novemebr the 21st, 1967 by the then Minister for Education, Mr Loveday.

Five additional classrooms, an open space unit and two transportable units were gradually added to cope with the steady increase in numbers. In 1977 school enrolments numbered 515 and class numbers were unacceptably high, hence pressure began mounting for an additional Primary School to be built in the town.
