Understanding why LENA programs work


Through a focus on actionable feedback and coaching, LENA has helped communities all over the world provide programs for parents and teachers that create sustainable increases in the quality and quantity of talk with children. Many independent evaluations have shown similar results with LENA: stronger families, improved classroom quality, and increased early literacy and school readiness. For studies validating the accuracy of LENA technology and its proven effectiveness in interventions and research studies, see our full bibliography of more than 100 peer-reviewed publications. Read on to learn about some of the evaluations and studies demonstrating the effectiveness of LENA’s programs:


LENA Grow

LENA Grow is a job-embedded professional development program designed to measure and improve the quality of early childhood programs. It is implemented through trusted community partners including human service organizations, county and state-level agencies, and school districts. LENA Grow has been shown to help teachers increase interaction, individualize their communication for each child, and build responsive caregiving skills, leading to improved teaching practice and measurable increases in scores on independent assessments of classroom quality.

LENA Start

LENA Start is an evidence-based group program for families that uses regular feedback from LENA technology to help increase interactive talk between adults and young children. Children whose caregivers participate in the program reap the benefits of an enriched environment, showing measurable improvements in key aspects of language development. LENA data show that children whose families participated in LENA Start are showing elevated language skills one year after the program, according to an analysis of longitudinal data. As home language environments are transformed, communities are transformed, and an early-language focus builds to city-wide impacts.
