Case study: ACT practice score gains with How To Student
An observational analysis of 614 enrolled students found broad participation and measurable score growth. Of the 516 students who completed at least one practice session, 329 improved their practice ACT score.
Cohort progression
Note. “Practiced” indicates completion of at least one ACT practice session. The improved group represents 63.8% of active participants and 53.6% of the full enrolled cohort.
Average gain
Average practice ACT score gain among the 329 students whose practice ACT scores improved.
Methods & interpretation
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.
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.
