Cornerstone Academy Charter

Cornerstone Academy Charter is a K-8 public charter school in Belle Isle, FL, serving 1,094 students within the Orange school district.

Cornerstone stands out for its exceptional academic consistency and remarkable efficiency. It has earned a 4-star rating from SchoolDigger for the past decade, with state rankings consistently in the 78th to 86th percentile. This high performance is achieved at a large scale—nearly four times the enrollment of nearby Pinecrest Preparatory Charter—while maintaining proficiency rates that often match or exceed those of smaller, high-performing peers like Blankner K-8. The school also demonstrates outstanding results in advanced coursework, with 100% proficiency in Geometry and 97% in Biology 1 on End-of-Course exams. Perhaps most notably, Cornerstone achieves these results with the lowest per-student spending among nearby schools with available data ($8,561 per student), compared to $13,505 at Blankner and $19,068 at Conway Elementary.

A key differentiator is Cornerstone's remarkably low chronic absenteeism rate of just 11.6% in the 2023-2024 school year. This is dramatically lower than the district average of 35.2% and the state average of 31.4%, and it also beats high-performing peers like Pinecrest (16.3%) and Blankner (17.6%). This suggests a highly engaged student body and a strong school culture that prioritizes attendance. While the school excels overall, it shares a common challenge with other K-8 schools in the area: a noticeable dip in 7th-grade math proficiency, which drops to 48% at Cornerstone, mirroring a statewide trend. This pattern, combined with the school's decade of stable, high performance and efficient spending, points to a deeply embedded culture of success.
