Triangle Lake Charter School

Summary:

Triangle Lake Charter School is a public charter school located in Blachly, Oregon, serving 406 students from kindergarten through 12th grade. As an alternative school, it offers a unique educational approach compared to traditional public schools in the area.

While the school's spending per student is higher than the state average, its test scores in English Language Arts and Mathematics are generally lower than the state's, particularly in the upper grade levels. However, the school's 4th grade ELA proficiency rate was higher than the state average. The school also has a relatively high percentage of students from low-income families, with 28.08% receiving free or reduced-price lunch in the 2022-2023 school year. The student-teacher ratio at Triangle Lake Charter School has fluctuated in recent years, ranging from 13.4 to 22.2.

Comparing Triangle Lake Charter School to the nearby Alsea Charter School, which is also a public charter school serving a similar grade range, Alsea Charter School generally performs better on standardized tests, with higher proficiency rates in both ELA and Mathematics across most grade levels. This suggests that the educational approach or resources at Alsea Charter School may be more effective in supporting student academic achievement. Understanding the unique educational model and strategies employed by Triangle Lake Charter School could provide valuable insights for the school and the broader educational community.

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.
