Millerstown education began in 1808 when the Presbyterian Church served as the first schoolhouse beside the church cemetery on Grave Street. In 1834 the borough enlarged the school and combined it with a Juniata River school into one district, excluding adjacent Greenwood Township. As the town's population grew, a large two-story frame school building was constructed on High Street in 1856, and it survives today as an apartment building. An addition a decade later expanded capacity to several hundred students, and the first graduation of five twelfth-grade students was held in 1887. In 1925 a new frame building was erected one block north of the original High Street School. In 1948 the Greenwood Joint School District was formed by merging the Millerstown district with those of Greenwood and Tuscarora Townships, and Liverpool Township joined in 1949. The 1925 school was updated and used until 1954, when a new Greenwood High School opened at 405 East Sunbury Street. In 1980 a new elementary school completed a modern educational complex with enrollment of approximately 750 students. Higher education also took root here when Silas Wright, a local educator and author of the first history of Perry County, established the Juniata Valley Normal School in Newport in 1867 and moved it to the High Street schoolhouse in Millerstown in 1868. A later historian, H. H. Hain, wrote that the location offered easy access from every section of the county and from the east and west on the Pennsylvania Railroad, allowing students to travel to Millerstown. Hain observed that with this opportunity for higher education, dozens of students became educators, lawyers, physicians, ministers, bankers, business men, and intelligent farmers and homemakers. At one time 160 students attended the five-month sessions, which cost $60 in tuition. The normal school closed in 1878, but the building remains today.
