Summary

Key Biscayne K-8 Center is a public school on Key Biscayne, FL, serving approximately 884 students in grades PK through 8 as part of the Miami-Dade district, and it has a long history of strong academic performance, consistently ranking in the top 15% of Florida elementary schools.

This school stands out for its exceptionally low rate of economic disadvantage, with only about 6% of students qualifying for free or reduced lunch—far lower than nearby schools like Silver Bluff Elementary School (53%) or Mater Academy East Charter School (84%). This affluent community profile correlates with high student engagement, as chronic absenteeism is just 10%, well below the district average of 28%. The school excels in early elementary grades, with math and reading proficiency rates consistently 10-20 points above state averages. However, a notable "middle school dip" emerges in grades 6-8, where English Language Arts (ELA) proficiency drops below district levels—for example, 7th-grade ELA was 47% compared to the district's 67% in a recent year. This contrasts with a peer like Ada Merritt K-8 Center, which achieves 91% ELA proficiency in 8th grade despite having a higher percentage of economically disadvantaged students.

Despite this literacy challenge, the school shows strengths in other areas. Eighth-grade science proficiency is a standout at 63%, significantly higher than the district (49%) and state (52%), and 8th-grade math and Algebra 1 scores are strong at 80% and 88%, respectively. The school spends about $11,304 per student and has a student-teacher ratio of 18:1. For parents, Key Biscayne K-8 offers a supportive, engaged community with excellent early education, but those with middle schoolers should pay close attention to literacy support, as this is the school's primary area for improvement compared to top-performing peers like Coconut Grove Elementary School.

Overcrowded school!. Not sure where they got the data for teacher/student ratio but in my experience, it has never been below 25 students per teacher Close Quote
