Zip code 07045 has four schools in the Montville Township School District: two elementary schools, one middle school and one high school, serving 2,478 students from elementary through high school. Results are generally well above state figures; for example, the two elementary schools averaged 70% in ELA and 72% in math, compared with state averages of 49% and 47%.

Valley View’s six grade 3–5 ELA and math scores averaged 75%, versus 67% at Mason; Valley View led five of the six matchups, including grade 5 math, 70% to 53%. Mason’s exception was grade 4 ELA, where it scored 72% to Valley View’s 64%. In grade 5 science, Valley View scored 59% and Mason 40%.
