The single score runs from 0 to 100 and is built from content mastery, progress, closing gaps and readiness, plus graduation rate for high schools. Georgia does not publish an A-to-F letter grade for schools in its 2025 data.

Georgia Milestones end-of-grade tests, 2025, share of tested students scoring Proficient and Distinguished, the two upper achievement levels:

Subject Proficient Distinguished
English language arts 18.5% 4.2%
Math 18.7% 5.7%

The same data put 28% of third graders and 33% of fifth graders reading at or above grade level.
