Sanislo Elementary School

Summary:

Sanislo Elementary School is a public elementary school in Seattle, Washington, serving students from kindergarten to 5th grade. With a diverse student population, the school has faced significant academic challenges, consistently ranking in the bottom quarter of Washington elementary schools.

Sanislo Elementary's performance on standardized tests, such as the SBAC and WCAS, is significantly lower than the state and Seattle School District averages. In the 2023-2024 school year, only 39.76% of Sanislo students were proficient or better in English Language Arts, compared to 52.63% statewide and 67.59% in the district. The math performance gap is even more pronounced, with only 26.51% of Sanislo students proficient or better, compared to 41.68% statewide and 58.68% in the district. The school's academic performance also varies significantly among different student subgroups, with the school ranking in the bottom quarter of Washington elementary schools for female students, male students, African American students, Hispanic students, and low socioeconomic status students.

Interestingly, Sanislo Elementary's academic performance is significantly lower than most of the nearby schools in the Seattle School District, such as Pathfinder K-8 School, Fairmount Park Elementary School, and Gatewood Elementary School, which all have much higher proficiency rates on standardized tests. The nearby Highline School District school, White Center Heights Elementary, also outperforms Sanislo Elementary School on academic measures, despite serving a similarly diverse and economically disadvantaged student population.

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.
