Public Grades 9-12

2090^th

SchoolDigger Rank ?

of 2,162 California High Schools

Better than 3% of California high schools

Summary

Carle (William C.) High (Continuation) is a small public high school in Lower Lake, CA, serving about 85 students in grades 9-12 who have faced challenges in traditional school settings, operating within the Konocti Unified school district.

The school faces significant challenges, with academic proficiency rates below 3% in English, math, and science, which are far lower than the state average and even the district's other comprehensive high school, Lower Lake High. A critical issue is chronic absenteeism, with 91% of students missing a large portion of school, creating a major barrier to learning. While the graduation rate has improved to 80%, the dropout rate remains high at 18.5%.

Interestingly, comparisons show that other local continuation schools, like Natural High (Continuation) in the Lakeport Unified district, achieve much stronger results with similar students, including higher graduation rates, better test scores, and far lower absenteeism. This suggests that while Carle High serves a high-need population, its current performance is not typical of all alternative schools in the area, indicating potential for improvement with targeted support and interventions.
