West Morris Regional High School District  The West Morris Regional High School District is a limited purpose regional public high school district in New Jersey that serves students from the surrounding Morris County communities of Chester Borough, Chester Township, Mendham Borough, Mendham Township and Washington Township. Elementary school students of the constituent municipalities attend separate K-8 school districts maintained by four of the five municipalities; Chester Borough and Chester Township schools are consolidated under the Chester School District and the remaining three municipalities each have their own districts (Mendham Borough Schools, Mendham Township Public Schools and Washington Township Schools). As of the 2017-18 school year, the district and its two schools had an enrollment of 2,519 students and 192.8 classroom teachers (on an FTE basis), for a student–teacher ratio of 13.07:1. The district is classified by the New Jersey Department of Education as being in District Factor Group "I", the second-highest of eight groupings. District Factor Groups organize districts statewide to allow comparison by common socioeconomic characteristics of the local districts. From lowest socioeconomic status to highest, the categories are A, B, CD, DE, FG, GH, I and J. Both schools in the district are fully accredited by the New Jersey Department of Education, the Gilder Lehrman Institute of American History and the International Baccalaureate program. In August 2015, West Morris Central (ranked 151st) and Mendham (18th) were ranked among "America's Top High Schools 2015" by "Newsweek" magazine. The West Morris Regional High School District is the only school district in New Jersey to offer students both the International Baccalaureate Diploma and Career programs. West Morris Mendham High School was ranked as the 7th most challenging public, non-magnet, non-charter high school in 2017 by "The Washington Post". The district was established in March 1956, with the first school opening on September 1, 1958, at what is now West Morris Central. The district originally included Mount Olive Township, until that municipality voted to leave the regional system. Students from Mount Olive Township attended West Morris Central High School until 1972. West Morris Mount Olive High School, in Flanders, opened in 1972 and was operated by the regional district until the 1978-1979 school year, with the West Morris Mount Olive High School Class of 1978 being the last graduating class from this facility under the regional administration. The high school building and remaining faculty became part of the Mount Olive Township School District and is operated as Mount Olive High School.
