Summary:

Thunder Mountain High School is a public high school in Juneau, Alaska, serving 586 students in grades 9-12. The school is part of the Juneau Borough School District, which is ranked 16 out of 24 districts in the state.

Thunder Mountain High School stands out for its diverse student population, with 48.63% White, 9.9% Hispanic, 7.34% Asian, 11.6% Native American, and 19.28% two or more races. This diversity is higher than the nearby Juneau-Douglas High School: Yadaa.at Kale, which has a 46.38% White student population. Academically, the school has shown strong performance in the past, ranking 7th out of 61 Alaska high schools in 2020-2021 and earning a 5-star rating from SchoolDigger. However, its ranking has declined in recent years, dropping to 31st out of 63 schools in 2023-2024 with a 3-star rating.

Thunder Mountain High School has performed well in serving certain student subgroups, such as Asian and Hispanic students, but has struggled with the performance of Native American students. The school has also faced challenges with its low socioeconomic status (SES) students, ranking 25th out of 41 Alaska high schools in 2023-2024. Addressing these disparities and the overall decline in academic performance will be key priorities for the school and district moving forward.

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.
