The Minnesota Nursery & Landscape Association, in collaboration with the University of Minnesota as well as other institutions of higher learning, offers the Certified Professional designation.  MNLA-CPs have studied a broad range of horticultural topics and have then passed a rigorous examination of general industry knowledge, as well as an examination within their specialty field (grower, garden center, or landscape).  MNLA typically offers the certification exam twice each year, once in January and again in March.
