Original Research by School Decision on Interlake Senior High School
Interlake Senior High School is a large regular public high school in Bellevue, serving grades nine through twelve as part of the Bellevue School District. The school sits in a city that functions as the high-tech and retail hub of the Eastside, a place where towering downtown office blocks sit alongside woodsy suburban neighborhoods threaded with trails. The local economy is dominated by major technology employers including Amazon, T-Mobile, Meta, and TikTok, and the city has seen rapid population growth, becoming majority non-white and roughly one-third foreign-born. Light rail now connects Bellevue to Seattle and Redmond, and large-scale redevelopment is reshaping the Bel-Red and Spring District corridors. The housing market reflects this affluence: home values are among the highest in the region, and rents are steep, which shapes the demographic profile of families who can live in the attendance area.
The student body is diverse and large. Asian students make up the largest plurality, followed by white students and a substantial Hispanic population. More than a quarter of students qualify for free or reduced-price lunch, a share that stands out in a city known for its wealth but also reflects the area’s economic range. The school’s size is typical for a comprehensive high school in this district, drawing from neighborhoods across eastern Bellevue.
Academically, the most recent state assessments show strong results. In English language arts, a large majority of students met the proficiency standard. Math and science proficiency are also solid, though the math figure is somewhat lower than the ELA figure, a pattern not uncommon in high schools. These results come from a single year, so no trend is available to show improvement or decline over time. The school has no reported graduation rate in the data, and chronic absenteeism figures are also absent, which makes it difficult to assess how many students complete high school on time or how regularly students attend. A parent may want to follow up with the school directly for those metrics, as they are common questions for high school evaluation.
No information was provided on advanced coursework such as Advanced Placement or International Baccalaureate, dual-credit programs, or career and technical education pathways. These offerings are often a central part of a high school’s academic profile, and their absence from the data does not mean they are missing at the school, only that they were not part of this dataset. The comparison set that places this school relative to other districts in King County could not be applied because the needed metrics were not available, so there is no external benchmark from that analysis.
The district itself, Bellevue School District, did not have any recent parent-relevant changes reported in the data available, so there is no notable shift in policies, boundaries, or programming to describe.
For families, Interlake Senior High School sits in a well-resourced community with strong test performance in the core subjects. The student population is academically oriented and reflects the broader city’s ethnic and economic diversity. The main gaps in the public record are outcome measures beyond proficiency, especially graduation rate and attendance. Anyone evaluating this school for a student should seek those figures directly from the school or district, along with details on the breadth of the academic program. The surrounding Bellevue housing market is expensive, which shapes the practical options for families considering the school as part of a move.
