Partners with Head Start

The effects of great teaching can last a lifetime for young learners. That’s why CLASS and Head Start are working together to ensure every child has access to high-quality educational experiences. For almost a decade, Head Start programs nationwide have been using CLASS to ensure compliance with national standards, while also providing their educators with the tools they need to create effective learning environments.

Head Start grantees are eligible for a free, one-time, one-month subscription to our CLASS Video Library so they can see effective interactions in action.
