English Classes for Adults

Build Community and Skills with Our English Classes for Adults

Intercambio makes learning English practical and fun! With Intercambio classes, you can improve your communication skills, build confidence, and connect to the community.

With two ways to learn, you have the freedom to choose what works best for you. Our Boulder County classes take place in-person, and our online program connects students and volunteer teachers living anywhere in the U.S.

We will place you in one of our seven levels of classes according to your current English ability.
