Original Research by School Decision on Horace Mann Elementary
Horace Mann Elementary, serving kindergarten through fifth grade in Redmond, sits within the Lake Washington School District. The school is a regular public elementary school in a city that functions as both a major technology employment hub and a residential community for the Seattle region. Redmond is best known as the home of Microsoft and Nintendo of America, and its economy and housing market reflect that. The median home value in the school's zip code is among the highest in the region, and the area has seen rapid growth, densification, and recent light rail connections to Bellevue and Seattle. For families considering this school, the housing market is a major factor: it is a high-cost area where even renting is expensive, and the school serves a student population with a very low share qualifying for free or reduced-price meals, reflecting the broader affluence of the neighborhood.
On state assessments administered in the 2024-25 school year, Horace Mann students performed at a very high level across all tested subjects and grades. In both math and English language arts, the proportion of students meeting proficiency standards was well above the midpoint for King County districts overall. Third graders posted particularly strong results in reading, and fifth graders did so in writing and science as well. The school's combined proficiency across all tested areas places it in the top quartile among elementary schools in the county's districts. This is the kind of academic profile that signals consistently strong classroom instruction and a student body that, on average, arrives well prepared.
The student body at Horace Mann is roughly a medium-sized elementary school. The largest racial or ethnic group is Asian, making up close to half of enrollment. White students account for about a third, with smaller shares of students who identify as two or more races, Hispanic, Black, and American Indian or Alaska Native. One characteristic that stands out is the low share of students who qualify for meal assistance. That figure is below the county average by a wide margin, which matters for understanding the peer environment families will find here.
Data on two important student support indicators is not available in the records we reviewed. Information on the share of students who receive special education services through an Individualized Education Program, and on students classified as English learners, was not reported in the school's data. A family looking into whether the school's supports match their child's needs may want to follow up directly with the school or district for those details. Similarly, chronic absenteeism data is not available for this grade band, and there is no graduation rate to report, as the school does not serve high school grades.
The surrounding community has seen significant investment and change in recent years, including new office campuses for major tech firms and the extension of light rail into downtown Redmond. The city has two distinct urban centers, and residential neighborhoods ring the downtown. Horace Mann itself sits in a residential area. The district, Lake Washington, did not have any major recent changes reported in the materials we examined, so families should rely on current school communications for any updates on curriculum, boundaries, or programming.
For families who can afford the housing market or are already in the area, Horace Mann offers a strong academic track record with very high proficiency rates and a student body that is economically homogenous at the low-poverty end. The missing special-population data is a gap worth probing, but on the measures available, the school delivers consistently strong results.
