Original Research by School Decision on Windsor Elementary School
Windsor Elementary is a public school serving kindergarten through fifth grade in Arlington Heights, a Chicago northwest suburb. The school sits within Arlington Heights School District 25 and serves roughly half a thousand students across its grade band.
The school's state assessment results show proficiency rates ranging across its tested grade levels. In third-grade mathematics, students performed near three-quarters proficient or above. Fourth-grade mathematics dipped lower, and fifth-grade mathematics was near seven-tenths proficient. In English language arts, third grade reached similar rates, fourth grade was notably lower at around three-fifths proficient, and fifth grade recovered to near three-quarters. Fifth-grade science proficiency was near seven-tenths. The school's overall proficiency index across tested subjects and grades places it in the top quartile among Cook County school districts, a reflection of solid performance across the elementary band.
Students at Windsor are predominantly white, with smaller populations of Hispanic students, Asian students, and other groups. The school's enrollment includes students across the kindergarten-through-fifth-grade span as its primary mission, though a handful of sixth-, seventh-, and eighth-grade students appear in the enrollment data, likely reflecting administrative or transition reasons rather than the school's regular grade structure. Data on free-or-reduced-price lunch eligibility and counts of students with individualized education plans was not available, so a full picture of economic circumstance or special education prevalence cannot be drawn from the materials provided.
The broader district context matters here. Arlington Heights SD 25 approved a substantial bond measure in 2022 by the narrowest margin, authorizing infrastructure investment and the transition from half-day to full-day kindergarten beginning in 2024. This means families enrolling a kindergartener at Windsor are stepping into a newly restructured program, with newly built classrooms supporting the expanded day. The referendum also raised property taxes measurably, a factor worth understanding if you are comparing housing costs and school support in the district.
Arlington Heights itself is a transit-oriented suburb north of Chicago with a revitalized downtown anchored around the Metra station, mixed with traditional single-family residential blocks. Major employers including Northwest Community Healthcare, Amazon, United Airlines, and others anchor the local economy. Housing values in the area are moderate to mid-range for a Chicago-area suburb, and the market has seen steady activity alongside broader regional patterns.
Windsor Elementary's location on East Miner Street places it within the residential fabric of the village rather than in the downtown core, and the school serves its neighborhood as a neighborhood elementary school. State test data was the most recent available metric; other measures such as chronic absenteeism, discipline, or staffing details were not in the provided data, so a full operational picture is incomplete. A parent considering Windsor might look into the school's specific current practices around reading instruction, math support in the fourth-grade range where results dipped, and what family engagement looks like across the building.
