Lost River High School

Summary:

Lost River High School is a public high school located in Merrill, Oregon, serving grades 7-12 with a total enrollment of 228 students. The school is part of the Klamath County School District, which is ranked 88 out of 140 districts in Oregon and has a 2-star rating from SchoolDigger.

Lost River High School has consistently outperformed the Klamath County School District and the state of Oregon in English Language Arts (ELA) proficiency for 11th grade students, with 60% proficiency in 2023-2024 compared to 50.5% for the district and 45.2% for the state. However, in mathematics, the school's 11th grade proficiency rate of 20% in 2023-2024 is on par with the state average but higher than the district's 19.2%. The school also performs well for Hispanic and low socioeconomic status (SES) students, ranking 20th and 26th out of Oregon high schools, respectively, in 2023-2024.

Despite these strengths, Lost River High School's statewide ranking and SchoolDigger rating have fluctuated over the years, suggesting the school may be facing challenges in maintaining consistent academic achievement. Nearby Henley High School consistently outperforms Lost River High School and the Klamath County School District in academic proficiency, while Bonanza Junior/Senior High School has a more mixed performance. The high percentage of free and reduced-price lunch recipients at Lost River High School, along with its strong performance for low-SES and migrant student groups, suggests the school may be effectively supporting economically disadvantaged students, but there is still room for improvement, particularly in mathematics and science proficiency.

As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
