Letter grades are based on numerical scores that are compilations of the 2019 ACT Aspire exams, achievement over time, and data such as student attendance. Alternative education schools and closed schools are not included.

High school letter grades take 2017-18 graduation rates into account along with other factors.
A total of 175 schools will receive cash rewards for achievement or academic growth on state-mandated ACT Aspire tests.

Rewards must be used for employee bonuses, equipment and materials, or personnel for supporting student performance.
