With no other middle schools in the ZIP code, families cannot compare local schools against one another using these figures. The most important finding is that in 2025–26, the school’s proficiency rates were well below state results in every subject: by 34 percentage points in ELA, 31 in math, and 25 in science.
Upper Lake Middle is both the highest- and lowest-scoring school in this one-school group, so that is not a meaningful distinction between peers. In 2025–26, 15% of students were proficient in ELA, 8% in math, and 11% in science; statewide results were 49%, 38%, and 36%, respectively. Science was the school’s strongest subject relative to the state, while ELA had the largest gap. SchoolDigger ranked the school 2,620th of 2,703 statewide, in the 3rd percentile, and gave it 0 stars.
Results were mixed from 2024–25 to 2025–26: the school’s science proficiency rose by 5 percentage points, while math fell by 4 points and ELA slipped slightly; meanwhile, the state’s average across the three subjects rose from 40% to 41%. SchoolDigger’s ranking also declined, from the 14th percentile in 2023–24 to the 3rd percentile in 2025–26, an 11-percentage-point drop. Other context: in 2024–25, the student–teacher ratio was 21:1 and 81% of students were free/reduced lunch eligible. Chronic absenteeism in 2025–26 was 30%, below the Upper Lake Unified rate of 37% but above the state’s 18%. These figures describe the school’s context, not the causes of its results.
