Sauvie Island School

Summary:

Sauvie Island School is a public charter elementary school serving 211 students in grades K-8, located on Sauvie Island just outside of Portland, Oregon. This exceptional school has consistently ranked among the top elementary schools in the state, earning a 4-star rating from SchoolDigger.

Sauvie Island School's academic performance is truly impressive, with students consistently outperforming the Scappoose School District and the state of Oregon in proficiency rates for English Language Arts, Mathematics, and Science. For example, in 2023-2024, 66.7% of 3rd graders at Sauvie Island School were proficient or better in ELA, compared to 58.8% in the Scappoose district and 39% statewide. The school also stands out for its relatively low percentage of students from low socioeconomic backgrounds, with only 19.91% qualifying for free or reduced-price lunch in 2022-2023, compared to nearby schools like Astor Elementary (64.4%) and Cesar Chavez K-8 (64.59%).

Another key factor contributing to Sauvie Island School's success is its relatively low student-teacher ratio of 16 students per teacher in 2022-2023, compared to higher ratios at nearby schools like Grant Watts Elementary (18.6) and Astor Elementary (15.4). This smaller class size likely contributes to the school's strong academic performance and ability to provide personalized attention to students.

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.
