Harrisburg Academy students head back to the classroom on August 27 as the school marks its 240th Anniversary. Founded in 1784 by John Harris, Harrisburg Academy is one of only three Pennsylvania Full Continuum International Baccalaureate Pre-K to Grade 12 schools. HA offers the Primary Years Programme (PYP), Middle Years Programme (MYP), and Diploma Programme (DP) – the only such school in Central Pennsylvania and one of just 2% of schools in the United States. It is the nation’s oldest, private, independent co-ed school of its kind.
