Summary:
The Clarkston School District has one middle school, Lincoln Middle School, serving grades 7–8 in Clarkston, Washington. The school enrolls 346 students, has a student-teacher ratio of 18.8 to 1, and reports a 56.94% free- or reduced-price lunch rate. Because Lincoln is the only middle school in the Clarkston School District, there are no local middle-school alternatives to compare within the district. Its 2025–26 performance shows a mixed picture: English language arts is the strongest subject, science is in the middle, and math is the clearest concern.
In English language arts, 47.34% of Lincoln students were proficient, just 1.02 percentage points below the district and 5.47 points below Washington overall. Results were nearly identical for 7th and 8th grade, and both grades slightly exceeded district results. Science proficiency was 42.05%, 3.31 points below the district and 8.90 points below the state. Math performance was much weaker: 26.92% of students were proficient, trailing the district by 6.91 points and the state by 16.19 points. Both grades need attention, although 8th grade math was somewhat stronger than 7th grade. The school was slightly above district grade-level math results, but statewide gaps remained large.
Recent trends make math the most important area for families to monitor. Math proficiency fell 6.61 points from 2024–25 to 2025–26, while ELA declined modestly by 1.21 points and science was essentially unchanged. Lincoln’s reported ranking also weakened, moving from the 49th percentile in 2023–24 to the 40th percentile in 2025–26, while remaining a 2-star school. Overall, Lincoln offers relatively steady performance across 7th and 8th grade and is closest to district expectations in ELA, but families should expect the greatest improvement needs in math. The stable science results and comparatively competitive ELA results are encouraging strengths to build on.
