Summary

This study tests whether a program called LENA Start can help parents talk more with their young children to improve language skills and school readiness. About 600 families with children aged 16-30 months will either take part in the program or receive usual care. Researchers will measure changes in home language environment and child development.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
LENA Start Program (behavioral intervention)
What this could lead to
If successful, this could provide a low-cost, scalable way for schools to help parents boost their child's language development and school readiness.
What could go wrong
This is an early-stage study with 600 families, and results may not apply to other communities. The program's impact on actual school performance is not yet proven.
