University of Massachusetts Winter School for Turf Managers


Winter School students participate in a grass ID lab. The UMass Winter School for Turf Managers is a certificate program designed to convey concepts essential to maintaining high quality turf, with emphasis on environmental stewardship and fiscal responsibility. This comprehensive, dynamic short course is especially suited for experienced professionals associated with the management of fine lawns and landscapes, golf courses, sports fields, parks, and municipal and private grounds.

Winter School is an excellent choice for practitioners who seek to expand their knowledge and practical skills. The program is also uniquely suited for those who want to advance in their career, but cannot schedule a two- or four-year program, as well as career changers who want to establish a solid foundation for entering the field of turf management.

About Turf Winter School

A typical Turf Winter School is a full-time, in-person program held each on the UMass Amherst campus for 6 weeks in January and February, with approximately 32 hours of instruction each week. Due to COVID-19 pandemic, Winter School was re-invented as a completely online program for the 2021 session. The virtual 2021 course ran for 12 weeks, from January 4, 2021 through March 26, 2021. Instruction was a combination of synchronous (live) and asynchronous (on-demand) content. The routine schedule included synchronous lectures/discussions/activities at 1:00 PM and 3:30 PM on Tuesdays and Thursdays for each week of the course. Synchronous content was recorded for on-demand viewing whenever feasible to allow for additional flexibility. Regular and consistent graded assessment activities were due throughout the course period to ensure that students were engaged and progressing appropriately.

For a less in-depth and less intensive turf management certificate course, take a look at UMass Extension's Green School.


A Certificate of Completion will be awarded to those who satisfactorily complete the program requirements.

Pesticide recertification contact hours will be offered for all New England states, and 9.6 Continuing Education Units (CEUs) are available.


The 2021 Winter School for Turf Managers has completed.

Winter School: A Distinguished History

The 'Massachusetts Agricultural College Winter Greenkeepers Class' circa 1930

The 'Massachusetts Agricultural College Winter Greenkeepers Class' circa 1930

Professor Lawrence S. Dickinson established the 'Winter School for Greenkeepers at Massachusetts Agricultural College' in 1927. The University of Massachusetts Winter School for Turf Managers, as the program is now known, was the first program of its kind and has run continuously with the exception of a three year hiatus during World War II. The program remains to this day a top source for turf industry professionals, and many UMass Winter School graduates hold positions of responsibility at prestigious fine turf venues throughout the United States, Canada, Australia and Europe.
