As of the 2020–21 school year, the district, comprising six schools, had an enrollment of 3,930 students and 342.8 classroom teachers (on an FTE basis), for a student–teacher ratio of 11.5:1.[1]
The district is classified by the New Jersey Department of Education as being in District Factor Group "J", the-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.[4]
Elections were held in both municipalities in November 1986 to consider joining the disparate school systems of the two communities into a combined regional district. This proposal was supported by the voters and since then, the two municipalities have shared a regionalized school district.[5]
For the 2025–26 academic year, the school district will shift its distribution of grades within the schools of the Borough and Township. Washington and Southern are set to go from K–3 to K–2, whereas Milton is set to go from pre-K-3 to pre-K-2; Lafayette will go from 4 to 5 to 3–4, and, finally, Chatham Middle School will add fifth grade to become 5–8.[6] These changes come in regard to age demographic trends and class sizes noted across both towns.
