The Bryn Athyn School District is a public school district in Montgomery County. While it is designed to serve residents of the small Philadelphia suburb of Bryn Athyn, it has never contained a school. 90% of students in the affluent and highly religious community attend private schools operated by the General Church of the New Jerusalem, which has its global headquarters in the borough. The remaining students attend Lower Moreland Township School District. The Bryn Athyn School District is one of just four in the state to not operate a high school; Midland Borough School District in Beaver County and Saint Clair Area School District in Schuylkill County have avoided consolidation by continuing primary education only, while Duquesne City School District, which features the lowest test scores in the state, in Allegheny County had its high school closed by state mandate.
