Could you have passed the 8th grade in 1895?

Notice that the exam took five hours to complete. There are questions about for whom it was intended. The original exam does not mention the eighth grade. The document describes itself as being administered orally and for "applicants." This makes one wonder if the exam was actually for newly graduated teachers. May be eighth grade was the highest qualifying exam to become a teacher in 1895 in the USA.
