Education​
The New Milford School District serves students in kindergarten through twelfth grade. As of the 2018–19 school year, the district, comprised of four schools, had an enrollment of 2,026 students and 157.4 classroom teachers (on an FTE basis), for a student–teacher ratio of 12.9:1. Schools in the district (with 2018–19 enrollment data from the National Center for Education Statistics[100]) are Berkley Street School with 436 students in grades K-5, Bertram F. Gibbs Elementary School with 484 students in grades K-5, David E. Owens Middle School with 510 students in grades 6-8 and New Milford High School with 601 students in grades 9-12.

In the 2011–12 school year, the high school introduced an academies program to the school, similar to the structure at the Bergen Academies. There are now sub-academies within the high school such as the school of sciences and the school of history.

Public school students from the borough, and all of Bergen County, are eligible to attend the secondary education programs offered by the Bergen County Technical Schools, which include the Bergen County Academies in Hackensack, and the Bergen Tech campus in Teterboro or Paramus. The district offers programs on a shared-time or full-time basis, with admission based on a selective application process and tuition covered by the student's home school district.

The Hovnanian School, founded in 1976 and dedicated to helping foster knowledge of Armenian culture and the Armenian language, serves students in preschool through eighth grade in the former Steuben School.

New Milford is the home of The Art Center of Northern New Jersey, a fine arts school and gallery offering classes for adults and children that was originally established in 1957 in Englewood, New Jersey
