Grayslake Middle School serves about 312 seventh-graders and about 351 eighth-graders in a regular public school setting within Grayslake CCSD 46, a district in Lake County north of Chicago. The school's most recent test data is from the 2024-25 school year, when the school administered Illinois state assessments in math, English language arts, and science across its two grades.
In math, seventh-grade proficiency stood at roughly the midpoint of the school's reported range, while eighth-grade math proficiency fell notably lower, less than one-third of students meeting or exceeding the state's proficiency standard. In English language arts, both grades performed similarly, with seventh and eighth grades each showing proficiency near or slightly above the midpoint. Science testing occurred only in eighth grade, where proficiency was the strongest subject result, with more than three-fifths of students meeting or exceeding the standard. School participation in assessments was high across both grades in all three subjects.
Relative to the Lake County districts serving similar grades, Grayslake Middle School's overall proficiency index sits below the county median. A parent may want to look into the school's specific approaches to math instruction, particularly at the eighth-grade level, and how the district supports students who do not meet proficiency benchmarks.
The school's enrollment is majority white (about one-half) with a substantial Hispanic population (roughly one-quarter to one-third) and smaller Asian, Black, and multiracial populations. Data on the proportion of students who qualify for free or reduced-price lunch, students receiving special education services, and English learners were not available.
The broader district context matters here. In March 2024, voters approved a new funding referendum—called "Maintaining Excellence"—that provides ongoing resources for capital repairs, safety improvements, and teacher retention. A consequence is a net reduction in the property tax rate once existing long-term debt is paid off in 2025. Additionally, beginning with this school year, grades five through eight across all district middle-tier schools underwent a significant daily schedule restructuring. The changes include consistent instructional time blocks, a double block of English language arts in fifth grade, consistent math courses in grades six through eight, and band instruction available within the school day at grades six through eight. These changes affect how every student in Grayslake Middle School's grade span experiences the day.
Grayslake itself is a residential suburb with strong town identity. Center Street downtown contains shops and restaurants walkable from Gelatin Park and Central Park, and a community campus nearby clusters the library, aquatic center, senior center, and skate park. Two Metra stations provide rail access to Chicago. The housing market has grown steadily, with median home values in the mid-to-upper range for the suburban region and rents climbing at rates outpacing the broader area. New residential construction remains active, and the village is planning substantial development including a data center campus for artificial intelligence computing.
