Original Research by School Decision on Dilley Elementary School
Dilley Elementary School serves kindergarten through fourth grade in Forest Grove, a commuter town in the Portland metro area that still holds onto its small‑farm‑town character. The school is part of Forest Grove SD 15, a district with eight elementary schools and five secondary schools distributed across the city. Dilley sits in a residential section of Forest Grove, a place where the downtown core along Pacific Avenue and Main Street offers locally owned restaurants, breweries, and a Wednesday evening farmers market, while the western and northern edges of town open onto rural acreage and vineyard views. Pacific University’s campus anchors the center of the city, integrated with the commercial district rather than separated from it.
The school is small for its grade band. Enrollment gives each grade a modest number of students, which means classes are likely to be relatively intimate. A substantial share of students qualify for free or reduced‑price meals. The student body is predominantly white, with a Hispanic population and a multiracial population each making up a noticeable share, and small counts of a few other racial groups.
State assessment results are available for the 2024‑2025 school year. In third‑grade math, a majority of students met the proficiency bar, and in fourth‑grade math just over half did. In English language arts, third‑grade proficiency was lower, with under half of students meeting the standard, while fourth‑grade proficiency was comparable to the fourth‑grade math result, with about half of students proficient. Combined across tested subjects and grades, the school’s overall proficiency index places it in the top quartile relative to districts in Washington County. Only one year of assessment data is available for this reporting period, so there is no trend direction to examine.
Because Dilley ends at fourth grade, there is no graduation rate and no chronic absenteeism data to report. Parents considering the school for the full K‑12 arc will need to look at the middle and high schools in the district separately. The district brief turned up no recent parent‑relevant changes such as boundary shifts, program launches, or bond measures, though that does not mean none have occurred, just that they were not confirmed in the available search.
Forest Grove’s housing market is a relevant factor for families deciding where to live. The area’s home values are in a range that is near the state benchmark, and rents are around that same level relative to incomes. The town’s growth has come from both expanding city boundaries and new subdivisions, with housing stock that runs from older ranch homes on the east side to larger custom homes on acreage to the west and north. The city has a car‑dependent walk score overall, though the downtown core and the area around the university are walkable.
For a family weighing this school, the picture is straightforward. Dilley is a small elementary with solid math proficiency in the tested grades and English language arts proficiency that is lower, particularly in third grade. The school serves a high‑poverty population and operates in a community that blends small‑town amenities with proximity to the Portland metro job base. The lack of multi‑year testing data and the absence of information on student support populations such as English learners and special education students are gaps a parent may want to follow up on with the school directly.
