Original Research by School Decision on Jefferson Elementary School
Jefferson Elementary School is a regular public school in Succasunna, an unincorporated community that serves as the downtown and population center of Roxbury Township in Morris County. The school serves students from preschool through fourth grade, after which they move on to middle and high school elsewhere in the district. It is a school of moderate size for its grade band.
The academic picture is mixed, with a notable bright spot in fourth-grade English language arts. On the state’s NJSLA assessments, a strong majority of fourth graders met the proficiency benchmark in ELA, a result that points to solid early literacy instruction at that level. Third-grade ELA proficiency was lower, with less than half of students reaching the bar, a gap a parent may want to ask the school about, especially how reading support is structured in the early primary years. In math, just over half of fourth graders scored proficient, while third-grade math proficiency was slightly below half. Overall, the school’s combined proficiency across tested subjects and grades sits below the midpoint relative to other districts in Morris County.
The student body is largely homogenous in terms of income. A relatively low share of students qualify for free or reduced-price meals. Racially, the majority of students are white, with Hispanic students forming the next largest group, followed by smaller shares of Asian and Black students. Data on students with disabilities and English learners was not available in the provided records.
Jefferson Elementary sits in a community defined by suburban residential character. Succasunna is primarily made up of owner-occupied single-family homes, and home values in the 07876 zip code are well above the state average. The county housing market has seen active listings increase recently, but homes still sell quickly, with median days on market under a month. Route 10 is the main commercial corridor, and Horseshoe Lake provides recreational space with a playground and natural areas. The area has seen population growth in recent decades, though the district brief turned up no recent major changes or developments affecting the schools.
Because Jefferson Elementary ends at fourth grade, there is no graduation rate to report, and the school does not offer high school-level programs such as AP or career pathways. The focus is squarely on the primary grades. For a family considering this school, the central question is how the early academic experience aligns with their priorities. The school’s fourth-grade ELA results are a clear strength, while early math and third-grade reading show room for improvement. The relatively low poverty rate and stable suburban setting may appeal to families looking for a traditional elementary school environment within a well-regarded Morris County district. Those wanting a fuller picture of the upper grades would need to look at the district’s intermediate and secondary schools.
