The Osceola School District earned its highest district grade to date for the 2025-2026 school year, improving its overall accountability score from 62% to 64% of total possible points -- within one-tenth of a percentage point of an overall 'A' rating. Twenty-six schools earned an 'A' rating in the most recent cycle (20 district-operated public schools and six charter schools), across a district serving 87 public schools and 75,314 students.
Proficiency scores still trail the state average
Even with that improvement, Osceola School District's average math proficiency score is 41% versus a 53% Florida public-school average, and reading proficiency is 45% versus a 52% state average. That's a real, disclosed gap -- the district's grade trajectory is genuinely positive, but current average outcomes still run meaningfully below the statewide norm, and families should weigh both facts together rather than either alone.
Confirm the specific school for a given address
With district-wide averages this mixed and 26 individual schools earning 'A' ratings within the same district, the gap between a strong specific school and the district average is likely substantial. Check the Florida Department of Education's school-grades portal or the Osceola School District's own site directly for the specific school zoned to any Kissimmee address under consideration, rather than relying on either the district-wide grade trend or the average proficiency figures alone.
Key takeaways
- Osceola School District posted its highest-ever district grade for 2025-2026 (accountability score up from 62% to 64%, within 0.1 point of an overall 'A'), with 26 schools ('A'-rated) across a district of 87 schools and 75,314 students.
- Despite that improvement, district average proficiency still trails the state: 41% math (vs. 53% Florida average) and 45% reading (vs. 52% Florida average) -- a real, disclosed gap alongside the positive grade trend.
- The gap between the district average and individual 'A'-rated schools is likely substantial -- confirm the specific school zoned to a given address via the Florida DOE school-grades portal or the district's own site.
- Both facts (real improvement AND below-average current proficiency) are true simultaneously -- weigh them together rather than citing only the favorable trend.
