[1] Starting in September 2015, for ninth through twelfth grades, students from Merchantville attend Haddon Heights High School as part of a new sending/receiving relationship with the Haddon Heights School District that was approved by the commissioner of the New Jersey Department of Education, joining students from Barrington and Lawnside, who already attend the Haddon Heights school.

John Ellis, the New Jersey State Commissioner of Education, blocked Merchantville leaving the partnership on the grounds that it would cause more white students to leave Pennsauken High and turn Pennsauken High into a majority minority school.
