Summary

Kelso High School is a public high school serving approximately 1,390 students in grades 9-12 within the Kelso School District in Washington state, which ranks in the middle range of districts statewide.

The school presents a mixed picture, with a significant strength in its 90.2% graduation rate, which exceeds the state average and is comparable to nearby schools like Kalama High School. However, academic performance is a serious concern, particularly in mathematics, where only 14.83% of students are proficient—far below the state average and lower than all neighboring traditional high schools, including Castle Rock High School and R A Long High School. This has contributed to a decade-long decline in the school's overall state ranking.

Performance varies widely among different student groups; the school shows notable effectiveness in supporting homeless students but is struggling profoundly to serve students in special education. Compared to alternative schools within its own district, such as Loowit High School, Kelso High School successfully graduates the vast majority of its mainstream student population, indicating strong student engagement and support systems even amidst academic challenges.
