The earliest evidence of children receiving formal education in what is now Sanger Unified School occurred in 1860. Scottsburg, one of the first school districts organized in Fresno County, served a community on the Kings River. In the following one hundred fifty plus years, many new schools were organized while others were abandoned or consolidated.
