Fulton County Schools dominated a list of the best schools in Georgia based on the state’s report card for 2015.

Gov. Nathan Deal and his Office of Student Achievement on Tuesday released their list of the 187 top Georgia schools, and 23 were in Fulton.

The results are based on the state's College and Career Ready Performance Index. The highest performers were those that ranked at or above the 93rd percentile for their "achievement" score, while the greatest gainers ranked that way on their "progress" score, in each case based on an average over three years.

Here are the schools and the categories in which they excelled:
