Summary

Plymouth High School is a small public high school in Saint Helens, Oregon, serving grades 9-12 with only 85 students. The school is part of the St Helens School District 502, which is ranked 124 out of 140 districts in Oregon and has a 1-star rating from SchoolDigger.

Despite the relatively high per-student spending of $21,129, Plymouth High School has consistently ranked in the bottom 10-20% of Oregon high schools for the past decade, with a ranking of 267 out of 268 schools in the 2023-2024 school year. The school's academic performance, as measured by the percentage of students proficient or better in OSAS tests, is significantly lower than the state and district averages. For example, in 2023-2024, only 10% of 11th-grade students were proficient or better in English Language Arts, compared to the state average of 45.2% and the district average of 29.1%. The school also struggles with the performance of female students, white students, and low socioeconomic status students, all of which are significantly lower than the state and district averages.

The high percentage of students eligible for free or reduced-price lunch at Plymouth High School, at 58.82% in the 2022-2023 school year, suggests that the school serves a population with significant socioeconomic challenges. This may contribute to the school's low academic performance, as research has shown that socioeconomic factors can have a significant impact on student achievement. Additionally, despite the relatively high per-student spending, the school has a high student-teacher ratio of 17.9, which may suggest that resources are not being effectively allocated to support student learning.
