Miami Killian Senior High School

Miami Killian Senior High School is a public high school in Miami, FL, serving 675 students in grades 9-12 as part of the Miami-Dade district, and it stands out for its near-perfect graduation rate despite facing significant challenges with academic proficiency and chronic absenteeism.

While Killian boasts an exceptional graduation rate of 98.9%—well above the district and state averages—its standardized test scores tell a different story. For example, only 33% of students were proficient in Algebra 1, compared to 69% in the district, and just 46% were proficient in 10th-grade ELA. This gap is much wider than at nearby Southwest Miami Senior High, which has a similar graduation rate but significantly higher proficiency in both subjects. Additionally, Killian spends $17,503 per student, nearly double the spending of top-performing schools like Coral Reef Senior High School and Terra Environmental Research Institute, yet its academic outcomes are among the lowest in the area. This high spending with below-average results raises questions about resource allocation.

A major factor behind the low test scores is a severe chronic absenteeism crisis: 35% of Killian students were chronically absent in 2023-2024, far exceeding the district average of 28.2% and rates at nearby high-performing schools like Coral Reef (11.9%) and Terra (14.7%). On a positive note, Killian shows a strength in US History, where 72% of students were proficient, nearly matching the state average. However, the school is an outlier in a neighborhood dominated by high-performing magnet and choice programs, such as Archimedean Upper Conservatory and Terra, which rank in the 99th percentile. The primary challenge for Killian is to bridge the gap between its graduation success and academic performance by addressing the root causes of absenteeism.
