Winterhaven School, Portland OR - Test Scores & Data

Original Research by School Decision on Winterhaven School

Winterhaven School is a regular K-8 public school in southeast Portland, part of the Portland School District (1J). It serves grades kindergarten through eighth grade on a single campus and draws from the surrounding residential neighborhoods east of the Willamette River. The school is not a charter school and operates as a standard neighborhood-attendance school within the district.

The school’s student body is predominantly white, with a smaller but notable share of students who identify as two or more races. Smaller populations of Asian, Hispanic, and Black students round out the enrollment. A substantial minority of students qualify for free or reduced-price lunch. The school is on the smaller side for a K-8, with enrollment distributed fairly evenly across the elementary grades and a slightly larger cohort in the middle school grades.

Academically, Winterhaven posts proficiency rates that place it well above the typical range among districts in Multnomah County. Proficiency in math and English language arts across grades four through eight is consistently high. The strongest scores appear in fifth grade, where nearly all students meet or exceed state standards in both reading and math. The one notable dip is in seventh-grade math, where proficiency, while still above the county median, drops noticeably from the school’s own high marks in adjacent grades. A parent may want to look into this further with the school to understand what may be driving that grade-level pattern. Fourth-grade English language arts also sits a bit below the school’s typical high standard, though it remains strong. Science scores are solid, with fifth graders performing particularly well, while eighth-grade science is somewhat lower but still very good by district and county norms. Because this school does not serve high school grades, there is no graduation rate to report.

The school environment data on civil rights topics, such as discipline rates and special education identification, was not available in the provided information. The same is true for staffing details, chronic absenteeism, and course access. These are gaps a family may want to investigate directly with the school or district.

Winterhaven sits in a city that is dense, walkable, and well served by public transit, with a strong bike infrastructure. The neighborhood around the school at 3830 SE 14th Ave is a mix of single-family homes and multi-unit buildings, with commercial corridors along nearby streets like Division and Hawthorne. A family living in this part of southeast Portland has easy access to the city’s amenities, parks, and civic institutions. Housing values in the area are above national medians, consistent with Portland’s inner neighborhoods, and rents have been rising.

The district, Portland Public Schools, is in a period of notable transition. Enrollment has dropped substantially from pre-pandemic levels, leading to a school consolidation process that involves closures and mergers. In 2024, the district placed a large capital construction bond on the ballot to address facility needs, seismic safety, and accessibility, with the outcome affecting future property taxes and school conditions. These district-level dynamics mean that attendance boundaries and school assignments could shift in the coming years, something a parent considering Winterhaven should track.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
