 Dover High School had served students from Denville Township, Hanover Township, Hopatcong, Jefferson Township, Randolph and Rockaway Township, before those districts terminated their sending/receiving relationships and either created their own high schools or established relationships with other receiving districts.In September 2013, the school was one of 15 in New Jersey to be recognized by the United States Department of Education as part of the National Blue Ribbon Schools Program, an award called the "most prestigious honor in the United States' education system" and which Education Secretary Arne Duncan described as schools that "represent examples of educational excellence".The school was the 238th-ranked public high school in New Jersey out of 339 schools statewide in "New Jersey Monthly" magazine's September 2014 cover story on the state's "Top Public High Schools", using a new ranking methodology.
