High Schools in Klamath County School District

Summary:

Henley High School stands out as the top-performing school in the district, consistently ranking among the best in Oregon and earning a 5-star rating from SchoolDigger. The school boasts exceptional academic results, with over 80% of 11th-grade students proficient in English Language Arts and 66% in Science. Lost River High School also performs well, ranking 45th in the state and earning a 4-star rating. In contrast, Chiloquin High School has seen significant fluctuations in its performance, moving from a 2-star to a 4-star rating before dropping back to a 2-star rating.

Across the district, the high schools share some common challenges, such as high chronic absenteeism rates and a significant percentage of students receiving free or reduced-price lunch, indicating economic disadvantage. While the district's overall four-year graduation rate is above the state average, there are notable disparities in academic performance, with the top-performing schools significantly outpacing the lower-performing ones. Addressing these inequities and leveraging the strengths of the high-performing schools could benefit the entire Klamath County School District.
