Twelve out of 21 Gwinnett County high schools who had ACT composite scores for the last two years saw their mean scores rise during the 2019-2020 school year, district officials have announced.

Gwinnett has 24 high schools, but only 21 of them posted mean composite scores during both the 2018-2019  and 2019-2020 school years. The others include Phoenix High School, which posted no composite score for either year, and two new schools: the Paul Duke STEM High School, which posted its first composite score last year, and the McClure Health Science High School.
