Hansen Elementary, Mountain House CA

Original Research by School Decision on Hansen Elementary

Hansen Elementary serves kindergarten through eighth grade in Mountain House, a newly incorporated master-planned community in San Joaquin County. The school sits in one of several residential villages that make up the city, positioned at the center of a neighborhood organized around parks, schools, and growing commercial development. Enrollment is moderate for a K-8 school spanning nine grade levels, with a student body that is predominantly Asian, followed by smaller populations of Hispanic, white, two-or-more-races, American Indian/Alaska Native, Black, and Native Hawaiian/Pacific Islander students. A very small share of students qualify for free or reduced-price lunch, reflecting the area's homeowning, relatively affluent character.

Academically, Hansen performs at a solid level. In mathematics, proficiency rates across grades three through eight cluster in the upper seventy to low eighty range, with seventh grade performing notably higher. In English language arts, proficiency is comparable, though third grade is softer at around seventy and seventh and eighth grades perform strongest. Science proficiency, measured in grades five and eight, sits in the low-to-mid seventy range. Across both math and ELA, the overall proficiency index places Hansen in the top quartile relative to other schools in San Joaquin County districts, marking it as a stronger performer in its regional peer set. Only one year of state assessment data is available, so trend information is not present; a parent may want to look into whether these results reflect stable performance or growth patterns at the school.

The school draws from a community still in rapid construction and expansion. Mountain House is roughly halfway through its master plan and adding housing at a steady pace, with new neighborhoods and commercial amenities continuing to materialize. Most residents are homeowners in newly built properties, many commute to the Bay Area or Sacramento for work, and the community is organized explicitly around walkable, family-oriented neighborhoods with schools and parks as central anchors. Housing values have declined modestly in recent months but remain elevated; the local housing market reflects affordability stress relative to income, though renters may find rents manageable compared to the cost of ownership. The Lammersville Joint Unified School District, which operates Hansen, has recently opened a new K-8 campus nearby and expanded the district's only comprehensive high school to accommodate growth, so school capacity is being actively managed to match community expansion.

As a K-8 building, Hansen does not serve high school grades, so no graduation rate or high school program data apply. Special education and English learner enrollment data were not available. The district operates only through eighth grade in most buildings, with Mountain House High School as the single feeder high school serving grades nine through twelve for secondary students in the area.

This schoolLammersville Joint Unified, same grade

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
