Who was included

The study included all 614 students who signed up during the Spring 2026 semester. A student was counted as active after completing at least one practice session.

How improvement was measured

A student improved when a later practice ACT score was higher than their earlier score. Of 516 active students, 329 met this definition during the Spring 2026 semester.

How gains were calculated

The 31% average and 30% median include only the 329 students who improved. Their similarity shows that unusually large gains did not skew the average.

CONCLUSION

At a public high school in Arizona, more than four in five enrolled students practiced, and nearly two in three active participants improved their practice ACT score.
