Prior to the division of school sections, Hyndman had its own log schoolhouse constructed in 1842; the log building was used after hours for religious services and as a community hall. When Hyndman was divided into sections, the area became section #17 with the school being referred to as S.S. #17 Campbell's Mills School; the school was located between Hyndman and the small neighbouring settlement of Campbell's Corners. In 1852, the log structure had greatly deteriorated and was replaced in a new location, west of its former location on Hyndman Road, by newer a frame building. In 1875, the area was divided into two sections, S.S. #17 and S.S. #23; the western section remained #17 serving Campbell's Corners, while S.S. #23 was created near the intersection of Hyndman Road and County Road 22. The S.S. #23 school was replaced by a newer building in 1914, and the old frame schoolhouse was dismantled to have its materials recycled. Both schools closed permanently in 1964 due to the construction of larger, modern schools nearby and improved transportation.
