Imo, he should be classified as a Special Needs child and given appropriate assistance. While most children learn at the same rate in the same collective setting, some learn slower and others learn faster. The outliers shouldn't be pigeonholed into the cookie-cutter approach applied to those students within the 1st standard deviation from the mean.
That same philosophy can apply to behavioral as well as intellectual special needs. When I went to school in western NY, those children with behavioral issues did receive special attention and were often separated from the rest of us. I'm a little surprised you're facing such an obstacle, even if you are teaching in Florida.
