According to PIAA directory July 2016[5] The history of education in Littlestown dates back to 1747 when a Reformed minister, Rev.

Many people sincerely believed that free schools would engender indolence, increase crime, oppress the taxpayers and destroy individual liberty.

As a result of such thinking, a joint convention was held at Gettysburg College November 4, 1834, by the County Commissioners.

There were two schools established, one a log structure on East King Street, taught by John McSherry and Francis X. Deneckere established the first Catholic parochial school with Miss Mary Wilson as first teacher.

Public education so progressed in Littlestown that in 1871 a two-story brick building consisting of three classrooms and one recreation room was built.

The new building was constructed by John Eline, who was The Builder in those days, at a cost of $10,000 and boasted a hot water furnace and spacious rooms and halls.

On January 7, 1932, it was decided to construct a new building as a result of the congestion being experienced on East King Street, and this was to be located on a site north of the playground on Maple Avenue, at that time Long Alley.

William Eline was the contractor, son of the man who built the East King Street School; Stanley B. Stover did the electrical work and B.F. Redding the Plumbing.

The Board of Education consisted of Dr. Harry S. Crouse, Samuel E. Renneer, John A. Mayers, Emory H. Snyder, and Henry S. Stover.

The High School Faculty included Paul E. King, principal; Lloyd L. Stavely, Harold R. Shriver, Golda O. Hook, Josephine Stetser and Kathryn Snyder.

In the summer of 1950 extensive renovations were made in the Maple Avenue structure to accommodate an enlarged Industrial Arts program and to provide space for a music room and laboratory.

On February 11, 1952, the Joint Board of Education was advised of the increase in enrollments of the elementary schools and the lack of physical facilities.

On April 8 it was agreed to take an option on the proposal of Lloyd and Alma Crouse for twelve lots on East Myrtle Street and consider the gift of lands adjoining thereto as owned by I.H.
