About LENA Foundation

LENA Foundation is a national nonprofit headquartered in Louisville, Colorado, that uses audio-based technology, data, and program models to strengthen adult–child conversational interactions in the first five years of life. Its core products and programs (including the LENA recording and analytics system and the professional-development program LENA Grow, and family-facing programs such as LENA Start and LENA Home) are used by school districts, Head Start programs, public health initiatives, libraries, and researchers to boost language, literacy, and social-emotional outcomes for young children.

The EIN 26-3784465 has been verified as belonging to LENA Foundation (Louisville, CO) through nonprofit filings and public charity records. In the last 2–3 years LENA has expanded partner reach and published multiple independent program evaluations: its 2024 year-in-review reported 424 partner organizations and evaluation findings showing substantial improvements in kindergarten readiness, language/literacy measures, social-emotional outcomes, and teacher retention associated with LENA Grow implementation.

Notable achievements

Evidence-based program outcomes

Independent and internal evaluations (2022–2024) show LENA Grow participants had significantly better language and kindergarten-readiness outcomes than controls, with reported increases in language/literacy readiness (about 1.5x) and overall readiness (about 1.6x) in recent analyses.

Scale and partner growth

By 2024 LENA reported working with hundreds of partner organizations (424 partners reported in their 2024 year-in-review) — including Head Start programs, school districts, libraries, and public-health initiatives — to bring early-talk interventions to classrooms and families.

Research footprint

LENA technology and programs underpin a substantial body of research — the organization maintains a research library with 200+ peer-reviewed studies and has supported multi-site and peer-reviewed evaluations published in academic journals.
