Archimedean Upper Conservatory

Archimedean Upper Conservatory is a small, high-performing public magnet high school in Miami, FL, serving 306 students in grades 9-12 within the Miami-Dade school district. This school consistently ranks among the top in the state, currently holding the #8 spot in Florida, and boasts a near-perfect graduation rate of 100% in four of the last five years. Its academic excellence is driven by a low student-teacher ratio of 13.3:1, which allows for personalized attention, and a highly engaged student body, reflected in a chronic absenteeism rate of just 15.6%—roughly half the district and state averages.

The school’s performance on standardized tests is in a completely different tier compared to nearby schools. For example, in ELA, Archimedean scores between 92-96% proficient, while Miami Sunset Senior High School, located just 0.63 miles away, scores only 46-51%. In Biology and US History, Archimedean achieves 97-100% proficiency, and in Geometry, it scores 95%—a massive 49-point gap over the next best non-magnet school, Pinecrest Preparatory Academy Charter High School. The only nearby school in the same league is Terra Environmental Research Institute, ranked #9 in the state, while most other local high schools, like Miami Killian Senior High School and G. Holmes Braddock Senior High, rank in the bottom half of the state.

One interesting finding is a unique dip in Algebra 1 performance, where Archimedean scored just 50% proficient in 2024-2025, below the district average, though it was at 92% the previous year. This anomaly is worth investigating but does not overshadow the school’s consistent excellence over nearly a decade. Notably, the school’s success is not driven by spending alone—its per-student cost of $13,405 is higher than some peers but lower than others with mediocre results, reinforcing that its academic culture and selective admissions are the primary drivers of its top-tier outcomes.
