In 1864, during the creation of Lassen County there were six original school districts, Milford would become seventh the following year. On February 28, 1865, Milford residents petitioned the Lassen County Board of Supervisors for a school district of their own. After all, the Lake School, was some twelve miles to the north and the Long Valley School nearly twenty miles to the south. The board obliged.
One of the unique traits of Milford, is that its original and replacement school houses still stand—though since converted in private residences, and they are side by side. The first schoolhouse was built in the summer of 1865 by Ezra P. Soule and Henry C. Stockton for $500. As Milford continued to grow, so did its student population. In 1883, the voters there dealt with a contentious issue to pass a special tax for $160 to construct an addition—it narrowly passed. The school population just kept growing and the original school, even with an addition was not enough. Back to the polls. On May 12, 1888, the school district voters approved $1,400 bond measure for a new school house, that served the community for nearly eight decades.
While the Milford School experienced many ups and downs, like any institution, times were changing. Long gone were the horse and buggy days, replaced with paved highways and automobiles that resulted in the population decline of rural communities and Milford was of no exception. In 1965, the upper grade students at Milford were transferred to Herlong Elementary. The following year, the school struggled and only taught grades one through three. The following year it closed and was annexed to Janesville Elementary School District.
