Our MissionSee how and why we’re introducing language learning excellence across the US.

Going beyond language education

LLN is committed to more than just language education. LLN is grounded in holistic educational practices that prioritize developmentally and age-appropriate instruction; social-emotional learning; diversity, equity, and inclusion; and sociocultural competence.

Language education isn’t just another grade on the report card, but a way to understand different cultures, communicate across borders, and ultimately unlock the world. But not every student gets this opportunity. That’s where LLN comes in.

Our Mission

To meet the needs of schools and students across the United States without language learning opportunities. We aim to do this by providing you access to real teachers, a flexible curriculum, quality materials, and a range of resources.

A curriculum committed to excellence

We don’t believe in halfway. That’s why our teachers are experienced, our curriculum is innovative, and our technology is cutting-edge. LLN teachers meet state and national standards and, as lifelong learners, regularly complete professional development.
