Florida released the grades for each of its school districts this week. Duval County received an A this year, the same grade it got last year.
Clay, Nassau and St. Johns counties also managed the same achievement.
Baker County received a B, and Putnam got a C.
The state determines the grades by assigning points to each district based on student achievement in language arts, math, social studies and science.
St. Johns scored the most points out of the entire state, while Nassau came in second. Clay and Duval fell further down the list.
