Educational Service District 123

Educational Service District 123 is an active, non-charter public education agency headquartered at 3924 W Court St in Pasco, Washington. Serving the community within the expansive suburban landscape of the Kennewick-Richland metropolitan area, the agency operates a single specialized school facility dedicated to high school instruction across grades 9 through 12. Designed to support students in their final years of secondary education, the district's programming caters predominantly to upperclassmen, with the vast majority of its enrollment concentrated in the 11th and 12th grades as students prepare for post-secondary academic and career pathways.

According to federal educational records for the 2024–2025 academic year, the district serves a total of 353 students, including 197 male and 150 female learners. The student body represents a rich cultural background, composed primarily of 165 Hispanic students and 164 White students, alongside a diverse cohort of Black, American Indian, Asian, Pacific Islander, and multiracial youth. Under its specialized classification as an educational service district, standard full-time equivalent (FTE) staffing metrics reflect a regional support structure rather than direct classroom staffing. Families, students, and educational researchers can learn more about the district’s specialized secondary programs and regional services by contacting their administrative facilities directly or by visiting esd123.org.
