Original Research by School Decision on Adler Park School
Adler Park School is a small elementary school serving kindergarten through fifth grade in Libertyville, a residential village north of Chicago in Lake County. The school enrolls a diverse community of families, with the plurality of students identifying as white, and a meaningful representation of Hispanic, multiracial, and Asian students. The school sits in a stable, affluent community where housing values have appreciated and the rental market remains tight, making housing cost a consideration for families in the area.
Academically, Adler Park shows solid proficiency across the subjects and grades where state testing occurs. In English Language Arts, the school performs notably well in grades four and five, with the substantial majority of students meeting or exceeding state proficiency benchmarks. Third-grade ELA proficiency is somewhat lower, but still approaches three-quarters of tested students. Math proficiency is consistent across grades three, four, and five, with around four-fifths of students demonstrating proficiency. Science performance in fifth grade also comes in at approximately four-fifths of students proficient. When proficiency results across all tested grades and subjects are averaged, Adler Park ranks in the top quartile compared to other schools in Lake County. This is a genuine strength: the school is outperforming most peers in its region on standardized measures.
One boundary to note is that only grades three through five have state test results available; kindergarten through second grade are not assessed by state tests, which is standard practice across Illinois. This means the school's academic profile in early literacy and numeracy rests on school-level and classroom-level measures rather than standardized state data.
The school is part of Libertyville School District 70, which has undertaken deliberate curriculum and pedagogical shifts in recent years. Starting in the 2023-24 school year, the district adopted a new K-5 English Language Arts program grounded in the Science of Reading, a research-based approach to how children learn decoding and fluency. For the 2025-26 school year, the district introduced a new kindergarten entry process called Kindergarten Launch to Learning, in which incoming kindergarteners spend two full days observing and interacting in mixed groups before classroom assignments are finalized based on peer dynamics and learning styles. These changes affect how students at Adler Park experience early learning and reading instruction.
Libertyville itself is largely built out and relies on incremental site-by-site redevelopment rather than suburban expansion. The village has a preserved historic downtown anchored by Cook Park and Cook Memorial Library, with a Metra commuter rail station serving the Chicago market. The broader community is pursuing mixed-income development goals, with recent approvals for multifamily housing and attainable senior apartments. The median home value in the area is in the mid-to-upper range, and rental prices reflect a tight market with limited turnover, consistent with a mature suburban enclave. The median household income locally exceeds the national benchmark, and the unemployment rate sits slightly above recent national trends.
Adler Park serves families looking for a neighborhood elementary school with solid academic fundamentals in a stable, affluent residential setting. The school's consistent proficiency rates and top-quartile performance position it as a dependable academic choice for grades three through five. Families considering the school may want to connect directly with the district about how the new literacy curriculum and kindergarten transition model align with their child's learning style and needs, and to understand the school's approach to students across the full range of readiness and ability. Housing and rental costs remain a practical consideration for any family relocating to serve this school.
