In 1874, a report sent to the State Superintendent of Public Schools stated that of the 581 children of school age in the county, only 99 were attending school. (Another source places the school age population of Carter County in 1874 at only 487).[2] The 1874 report to the State Superintendent went on to say that there were only three school houses in the entire county and 25 teachers. The salaries of a male teacher averaged $16 a month while that of a female teacher averaged $10 a month.[3]
