The Hermiston School District is the largest district in eastern Oregon, exceeding 5,300 students in grades kindergarten through 12, with the mission of serving the needs of all students with rigorous and engaging program choices, mutual, respect, and high expectations. The school district includes a 9-12 senior high school, two 6-8 middle schools, and six K-5 elementary schools for students and families.
 

The district employs over 630 full time staff that includes approximately 390 teachers and over 260 classified, support, and supervisory personnel, making it one of the largest employers in the city of Hermiston. A nationally recognized community that embraces its diversity, the district serves some 28,000 residents, where half of the population is Hispanic.

Support for Hermiston School District has been strong from the community. In 2001 voters approved a $39 million building program, and in 2008 voters approved a $69.9 million bond. 
 

On November 5, 2019, the Hermiston community approved Bond Measure 30-130, an $82.7 million Hermiston School District 25-year bond. The measure will address student capacity, adding a 600-student elementary school on Theater Lane, and replacing the district’s oldest school, Rocky Heights Elementary, which was built in 1962. The bond also includes an annex to increase capacity at Hermiston High School, site improvements at elementary schools, and property acquisition for future growth.
 

On April 9, 2020, the district’s AA-credit rating enabled the HSD’s bond underwriter, Piper Sandler, to sell the bonds and refinance $2.8 million of a 2010 bond issue. The district gained an additional $1.7 million in bond premium and afforded the Hermiston community a savings of $382,448.
 

During the bond campaign, voters were told to expect a steady property tax levy rate of approximately $3.65 per $1,000 of assessed value for the life of the bond. Following the bond sale, rates are now expected to drop in 2030 to approximately $2.16 until 2045.
