Master Composter Class

Master Composter Certification Class

Become a certified master composter in Washtenaw County! Learn all about composting - from backyard composting, vermiculture (worms!), compost tea, and soils. Take a guided, technical tour of the Ann Arbor Municipal compost operation and receive a comprehensive binder of class and composting reference materials. A take home quiz is worked on collaboratively. Michigan Master Composter certification is available for students who pass the take-home exam and complete at least 10 volunteer hours in the community. 

The Master Composter Certification class is collaboratively organized by Project Grow, Washtenaw County and the Ann Arbor Public Schools (AAPS) Recreation and Education Program. Not sure if the class is right for you? View the 2019 class flyer
