Summary:
The 07878 list includes one school, Mount Tabor Elementary School, serving grades K–5 with 340 students; test results cover grades 3–5 in English language arts (ELA) and math, plus grade 5 science. Because there is only one school, families cannot compare schools within the ZIP code. Most importantly, in 2025–2026 Mount Tabor exceeded state results in every reported grade and subject.
Against state averages, Mount Tabor’s 2025–2026 results were higher by an average of 24 percentage points in ELA, 26 points in math, and 23 points in grade 5 science. Math was its strongest area compared with the state, but results varied by grade: proficiency ranged from 62% in grade 4 to 80% in grade 3. The school was not ahead of its district in every comparison: it scored 2 points lower in grade 5 ELA and 5 points lower in grade 4 math than the Parsippany-Troy Hills Township School District, while exceeding the district in the other listed subject-grade comparisons.
Results changed unevenly over time. From 2024–2025 to 2025–2026, grade 4 results fell by 10 points in both ELA and math, while grade 5 science declined by 10 points; math improved in grades 3 and 5, and the school remained well above state results overall. SchoolDigger’s ranking also moved down, from 93rd of 1,338 schools and the 93rd percentile in 2023–2024 to 159th of 1,331 and the 88th percentile in 2025–2026; its rating went from 5 stars to 4. Context figures include a 12.6 student-teacher ratio and 17% free/reduced lunch eligible in 2024–2025. Chronic absenteeism was 10% that year—above the district’s 7% but below the state’s 14%.
