Advance your turf management knowledge at your pace with GreenKeeper University.

Our team of renowned turfgrass professors, researchers and practitioners have moved to our courses to a 100% self-paced format. This means students can enroll in courses at any time and view hundreds of hours of lecture material on their own timeline. Our new learning management software automatically tracks student progress towards either an Introductory Certificate in Turfgrass Science or GKU Diploma.

The new Introductory Certificate course in GKU covers the principles of turfgrass science with a golf-turf focus, ranging from turf selection to soil fertility and pest management. This program is recommended for those new to the industry or those with experience wanting to update their practices. Students earn a certificate immediately upon completion of the program.

The advanced courses build on the fundamentals of turf science and management. These courses are a deep dive into their topic areas, taught by experts in their respective fields. While the Introductory GKU course is not a prerequisite to enroll in the Advanced courses, past turf management experience or education is recommended to excel in the Advance courses.

GreenKeeper University self-enrollment opens us on Monday, November 20, 2023. Students will have immediate access to the content upon registration. Learn more and enroll at
