The Ohio State University Lima has its own chapter of the National History Honor Society, Phi Alpha Theta. Only certain exceptional students of history will be invited to join this prestigious society, and membership is then for life. Phi Alpha Theta's Mission Statement reads:
We are a professional society whose mission is to promote the study of history through the encouragement of research, good teaching, publication and the exchange of learning and ideas among historians. We seek to bring students, teachers and writers of history together for intellectual and social exchanges, which promote and assist historical research and publication by our members in a variety of ways.
