Original Research by School Decision on Lincoln Union
Lincoln Union is a small rural elementary school serving kindergarten through sixth grade in unincorporated Petaluma, on Hicks Valley Road. It is part of Laguna Joint Elementary, a single-school district serving the rural Chileno Valley area.
The school's enrollment data shows zero students reported across all grade levels, which is unusual. This appears to reflect either a data reporting issue or a closure; the directory lists the school as open, but without confirmed current enrollment or recent enrollment trends, a parent should contact the district directly to understand the school's actual operational status before considering it.
State testing results for the school are fully suppressed across math, English language arts, and science for the most recent years on record. Suppression typically occurs when enrollment in a tested grade or subgroup falls below a threshold that would protect student privacy. This prevents any public assessment of the school's academic performance. The state does not report proficiency rates, average scale scores, or participation data for Lincoln Union. Given the zero-enrollment figure in the directory data, this suppression may reflect that the school is not currently serving tested students, though this would need confirmation from the district.
The locale data shows that Petaluma as a whole is a city of historic downtown architecture anchored along the Petaluma River, with commercial, residential, and light-industrial areas, transit anchors including free local transit and SMART rail service, and ongoing development activity. However, Lincoln Union's specific location on Hicks Valley Road places it in a rural, unincorporated part of the county outside the main city fabric, far from those civic amenities and walkable neighborhoods.
No current information is available about the school's program offerings, staffing, attendance patterns, special education services, or English learner support. The district brief noted no recent deliberate changes in curriculum, pedagogy, or property-tax measures specific to Laguna Joint Elementary.
Housing values in the Petaluma zip code are very high relative to national benchmarks, and rents are substantial, reflecting Marin County's overall real estate market. This context matters if a family is considering relocation to the area.
Given the data gaps, particularly the zero-enrollment figure and fully suppressed test results, a parent considering this school should reach out to Laguna Joint Elementary directly to confirm whether the school is currently enrolling students, what its actual student population is, and what academic and support services it offers.
