The North Haven Middle School is located in a residential neighborhood with single-family homes approximately 2 miles from the center of town. The building was built in 1960 as a Junior High School and later became one of two high school campuses. It now houses the three middle grades (6-8). The physical building is a neighbor to the North Haven High School (grades 9-12) on the same property. The schools share the campus with separate driveway entrances, one connecting access driveway, a ¼ mile running track and athletic fields and bleachers on the property. Renovations of the middle school took place in 1986.
The 2010-2011 enrollment of 841 students is projected to decline slightly since the overall population state-wide is declining. The building has two separate cafeterias with ample seating, a large and a small gymnasium, and an auditorium that seats 475. Each core teacher and teachers of special education have their own classroom. World Language, Reading and Unified Arts teachers also have their own classrooms. The library and the two computer labs provide supplemental information, materials and equipment for instructional use and all three resource areas are reserved by teachers and used daily.
Parents are instructed to drop off students at approximately 7:30 am when the busses start to arrive. All visitors must enter through the main entrance where they are acknowledged by an office staff member who unlocks the door. Visitors then report to the Main Office where they must sign-in and obtain a visitor's pass. This pass is returned and the visitor signs-out before they exit the building. External security is also provided by the School Resource Officer (SRO) housed at the neighboring high school during school hours, in the event of an emergency or a security breech.
North Haven Middle School is on the north side of town with close access to the Route 40 connector and Interstate 91. North Haven borders the towns of Northford, Branford, Wallingford, Hamden and the City of New Haven.
