This evaluation of PowerUp is a gold standard randomized control trial (RCT) that meets ESSA’s standards for STRONG research - the highest tier of efficacy evidence outlined by federal law.
PowerUp users gained on average more than 20 percentile points more than non-users on their end-of-year state assessment.
Results show that PowerUp is nearly 5x as effective as the average middle school reading intervention.
