Original Research by School Decision on Southridge High School
Southridge High School, a regular public school serving grades nine through twelve in Kennewick, Washington, is a large comprehensive high school within the Kennewick School District. A parent evaluating this school will find a student body that is both sizable and notably diverse in socioeconomic background, set within a city that is the most populous of the Tri-Cities and experiencing steady growth.
The student community at Southridge is mixed. A substantial share of students qualify for free or reduced-price lunch, a fact that signals a wide range of household incomes among the families the school serves. Racially and ethnically, the student population is predominantly white and Hispanic, with smaller numbers of students who identify as two or more races, Asian, Black, Native Hawaiian or Pacific Islander, or American Indian or Alaska Native. Data on students who receive special education services or are classified as English learners was not available in the reviewed materials, so a parent with a child in either of those categories should verify available supports directly with the school.
On state assessments administered in the 2024-25 school year, Southridge High School posted results that a parent should examine closely. Proficiency in English language arts was above the midpoint of possible outcomes, while proficiency in science was more moderate. The school’s performance in math was substantially lower, with a smaller share of students meeting the state standard. Because only a single year of test data was available in the source materials, there is no trend to judge whether these results represent a typical year or an outlier. A parent concerned about math achievement in particular will want to ask the school what interventions, course pathways, or support structures are in place for students who need them. Graduation rate data was not included in the information reviewed, so a family for whom that metric is important should seek it from the district or state report card.
Kennewick itself provides the context for the school. The city runs along the Columbia River and has a diversified economy that includes manufacturing, food processing, retail, and services, with offices for Amazon and Lamb Weston. The Hanford Site and the Pacific Northwest National Laboratory, located in nearby Richland, are major regional employers. Kennewick is part of the Tri-Cities area, described as the fastest-growing population center in Washington State. Growth is reflected in planned investments, including an expansion of the Three Rivers Convention Center. Housing values in the area around the school are close to the statewide benchmark but sit well above the national median, suggesting that owning a home near Southridge requires a higher-than-average income. Rents are more aligned with typical household earnings.
The Kennewick School District maintains a bonds and levies program, with voters deciding on funding for new buildings and major capital projects through bonds, and for ongoing programs and operations through levies. The district uses a Facility Study Committee to recommend capital projects based on enrollment growth projections. This suggests a district that is actively planning for its infrastructure needs in a growing region, which may be relevant for a family considering the long-term stability of the high school.
In sum, Southridge High School is the large public high school serving a growing and economically mixed section of Kennewick. Its academic picture from the most recent state testing is strongest in English language arts, more moderate in science, and notably lower in math, which is the primary area a prospective parent would want to investigate. The lack of graduation rate and special population data in the available information are gaps that would be important to fill before making an enrollment decision. The broader community is one of steady population growth and economic diversification, with housing that is expensive to buy but more accessible to rent.
