Can a free app bridge the literacy gap before kindergarten begins?
In short: A rigorous study suggests that digital tools might do more than just entertain. For children from low-income families, just ten weeks of using a specific educational app resulted in literacy gains comparable to dozens of private tutoring sessions.
A peer-reviewed randomized controlled trial, published in the Journal of Children and Media, has provided strong evidence for the efficacy of the Khan Academy Kids app. A study involving 49 children aged four and five from low-income Western Massachusetts areas was performed by University of Massachusetts Amherst researchers. These children were randomly assigned to either use the Khan Academy Kids app at home or use other age-appropriate, non-literacy-focused apps. The research utilized the Test of Preschool Early Literacy (TOPEL) to measure progress. This well-validated national benchmark ensured the data's accuracy.
The results were striking. Children who used the app for an average of 13 minutes per day showed significant pre-literacy gains in just 10 weeks. Specifically, those using the app for at least one hour per week saw overall literacy scores increase by 6.3 points and phonological awareness scores rise by 11.3 points. This phonological awareness gain is particularly vital, as it is a primary predictor of long-term reading success.
To illustrate the effect, external experts noted these improvements match what 25 private one-on-one lessons with a professional tutor achieve. Because the app is free, it offers a potential mechanism to narrow the school-readiness gap—a persistent disparity in foundational skills that is often already deeply entrenched by the time children enter kindergarten. The study noted that the median family income for participants was $24,000, highlighting the app's potential for families in low-income brackets. Notably, the study reported zero attrition among the Khan Academy Kids group. This suggests high levels of engagement throughout the trial.
