We are thrilled to offer our Nature-Based Teacher Certification as a multi-level program to provide in-depth study of best practices in nature-based early childhood education and prepare teachers for meaningful outdoor learning experiences. Each level offers 36-clock hours of training with in-person and online options available.
Whether you are in a formal school or childcare setting or working in a nature or forest preschool, this course is designed to meet the needs of early childhood educators working in any setting. Learn more about each level of certification below. (Note: See photos from the very first cohort of teachers to participate July 2018 in Baltimore, MD.)
Registration Options
Join us online OR in person! Registration now open for virtual six-week courses and for our in person, five-day training experiences (summer sessions). Please note that the online course is designed like an interactive college course and requires real-time participation with presenters. This is not a pre-recorded "on demand" class - you get to network with others as you learn.
