Original Research by School Decision on Flocktown-kossmann Elementary School
Flocktown-Kossmann Elementary School serves students from prekindergarten through fifth grade in Long Valley, an unincorporated community within Washington Township in western Morris County. It is a regular public school and the only elementary school in the Washington Township School District that covers this grade span. The school draws from a residential area with a historic village core and rural-suburban character, where the German Valley Historic District and the South Branch of the Raritan River anchor the community. Enrollment has been relatively stable in recent years, consistent with the slow-growth pattern typical of this part of the county.
Academically, the school performs above the midpoint among districts in Morris County in overall proficiency across tested subjects and grades, based on the most recent state assessments. In English language arts, results are a clear strength. The large majority of fourth graders met the proficiency threshold, and a strong majority of fifth graders did as well, while third graders scored somewhat lower but still with a majority proficient. In math, a solid majority of third and fifth graders were proficient, and fourth graders were a bit above half. Science is tested only in fifth grade, and here proficiency was notably lower, with a minority of students meeting the state standard. A parent may want to ask the school about science instruction and support in the upper elementary grades.
Because the school ends at fifth grade, there is no graduation rate to report, and the school does not administer state tests in the earlier grades, so no assessment data is available for kindergarten through second grade. Multi-year trend data was not available, so it is not possible to say whether scores are improving or declining. Information on special education and English learner populations was also absent from the data, so a family with specific support needs would want to inquire directly with the school about those services.
The student body is predominantly white, with smaller shares of Hispanic students, Asian students, students identifying as two or more races, and Black students. A very small share of students qualify for free or reduced-price lunch, indicating a low level of economic diversity within the school. The school serves roughly the same number of students across each grade, with a slightly larger fourth grade cohort.
Housing in Long Valley is expensive relative to state and national benchmarks, reflecting the broader Morris County market. Homes in the area have appreciated modestly over the past year, and listing activity has picked up. The area is not a fast-growth one; Long Valley’s population has shown slight decline over recent decades, and no major new developments were identified in publicly available sources. The community remains largely built out with larger lots and historic homes.
The Washington Township School District, which oversees Flocktown-Kossmann, operates four schools serving grades PK through eight. The district has a low student-to-teacher ratio, well below the state average, a structural feature that bears on class size. Per-pupil spending is high, with a substantial share of revenue coming from local property taxes. That fiscal profile shapes both the programming available and the tax environment for residents. No recent referendum or policy changes were identified in publicly available sources, so it is unclear whether the district has pursued new facility or program investments in the last several years. The district’s high local revenue share and spending levels are lasting characteristics that families weighing a move to the area would want to understand in relation to their own priorities.
