Original Research by School Decision on Half Day School
Half Day School serves grades three through five in Lincolnshire, an upscale suburb about thirty miles north of Chicago along I-94 in Lake County. The school is a regular public elementary school within Lincolnshire-Prairieview School District 103, located on Olde Half Day Road in the eastern residential portion of the village.
The student body is around six hundred students, with nearly even distribution across the three grade levels. Racial and ethnic composition is predominantly Asian and white, with smaller populations of multiracial, Hispanic, and Black students. Free-or-reduced-price lunch data was not available, and counts for students with individualized education plans or English learners were not reported.
On the Illinois Assessment of Readiness in math and English language arts, Half Day's proficiency rates cluster in the low-to-mid eighties across grades three and four. Third grade math and English proficiency both sit in the low eighties; fourth grade shows similar results in both subjects. Fifth grade dips slightly in math, to the mid-seventies, though English language arts rises to the mid-eighties. Science proficiency in fifth grade, measured by the Illinois Science Assessment, is around seventy-eight percent. These results place the school in the top quartile among Lake County school districts for overall proficiency across tested subjects and grades. Testing participation is at or near complete across all reported grades.
The school occupies a traditional elementary school role within the district; it feeds into middle school for students' sixth-grade year. Program offerings, staffing, attendance data, and other operational details were not available in the data provided. A school website was not listed.
Lincolnshire itself is a residential-corporate hybrid. The eastern half, where Half Day School sits, consists of large-lot single-family homes, townhouses, and condominiums set among wooded subdivisions. The western side along Milwaukee Avenue hosts a commercial spine with restaurants, retail, hotels, and corporate office parks. Housing in the zip code where the school is located carries median valuations in the high six figures, with year-over-year appreciation in recent years. Rental affordability is moderate; the median listing price per square foot suggests homes and units at entry levels still stretch household budgets. The village has recently begun adding multifamily housing, with the first purpose-built apartment complex completed in 2024 after decades as a single-family-dominated suburb.
Parks and recreation trails connect school, residential neighborhoods, and the Vernon Area Public Library, a community anchor about a mile away. Metra rail service is accessible via paths to nearby stations. Bus transit exists but is light; Lincolnshire is auto-oriented. The area's employment base includes several Fortune-level corporate headquarters such as CDW and Camping World, plus the Marriott Lincolnshire Resort, creating a stable if car-dependent suburban setting.
Half Day School's performance is solid for its affluent, college-prep-oriented community. Proficiency rates in the low-to-mid eighties are above the median for Lake County districts and mark it as a school where the majority of students meet or exceed state standards. The slight softening in fifth-grade math is worth noting and may reflect normal curriculum progression, but a parent may want to look into how the school approaches mathematical skill-building in that grade.
