District 16 Schoolhouse is an original one-room schoolhouse built in 1898 along the Michigan border, north of present-day Sauder Village. It was originally called Rosehill School and was renamed District 16 School when it was moved to Sauder Village in honor of the school attended by village founder Erie Sauder. One-room schools dotted the landscape of Northwest Ohio from the 1830s to the 1940s and could be brick, stone, or frame structures like this one. This school has two doors, one for boys and one for girls, though not all one-room schools included that feature. In such schools, all eight grades were taught together by one teacher, with students ranging from 6 to 21 years old. Students learned reading, writing, and arithmetic, and depending on the community and teacher, they might also study geography, grammar, and orthography, or spelling. Prospective teachers had to pass an examination given by local or county school boards in the basic subjects, and examiners also judged their moral character. In 1864, the State of Ohio began issuing teaching certificates recognized throughout the state.
