Volunteer Service Hours

Record your volunteer hours on one of two volunteer hour log sheets. Download 2019 Volunteer Log Sheet(s) in Word and Excel.

Hours are due by October 1. If hours are submitted later than October 1, access to CERVIS and other resources will be interrupted.

Continuing Garden Education hours:

  • Attend any MG training class offered from January - March at any of the 3 training locations. Morning sessions and afternoon sessions each count for 3 hours of continuing education. Attending the classes is a great way to brush up on the basics. The annual schedule is posted in the January and February MG newsletters.
  • The Clackamas, Multnomah, and Washington Co. Chapters all offer several speakers, seminars, and classes throughout the year that count as continuing education credit. Find designated speakers and classes designated on their Chapter pages, in the Metro MG newsletter or on the Educational Events Calendar. Always look for a designation like “approved for MG garden education credit” or “qualifies for continuing education credit”.
  • MG Program Hands-on Education Workshops. These workshops are part of the MG training curriculum offered by the metro-area MG program. Current Perennial Master Gardeners are allowed to take one of these workshops. Perennial Master Gardeners will be notified of workshops via the monthly newsletter.
  • Keep your eye out for additional designated continuing education credit opportunities as they surface throughout the year. Be sure to read the monthly MG program newsletter or email announcements.

This form is to be submitted annually, due October 1.

2019-2020 Conditions of Volunteer Service


Attend all 8 in-person classes (January through March)

Take and successfully pass REQUIRED modules which include:

  • Oregon Master Gardener Program: Learn the nuts and bolts of the Master Gardener program educational program.
  • Pesticide Safety: Understand how to read and interpret pesticide labels; learn how to safely mix, apply, handle, and dispose of pesticides.
  • Plant Pathology: Identify microorganisms that cause plant disease and symptoms; learn how to diagnose and control plant disease.
  • Diagnosing plant problems: Learn to gather information from clients, discuss plant growth and identification. Clearly assessing a plant problem leads to taking actions to resolve the issue. Save time and money by not treating problems you don't have.
  • Your choice: Complete one of the optional modules and complete the quiz.

Final exam

Successful completion of an exam is required to become a certified MG volunteer. The goal of the exam is to ensure that trainees meet learning objectives of the MG program. The exam is available and you must complete the final exam and 50 hours of volunteer internship in order to get an official OSU Master Gardener name badge and to be eligible to continue to volunteer in our program in subsequent years. You must pass exam with at least 70% by March 31 (training year) in order to participate in the OSU-sponsored volunteer activities like phone hotlines and OSU Master Gardener clinics at farmers markets and other venues.

Our local Master Gardener Chapters in Clackamas, Multnomah, and Washington counties provide monthly educational seminars on a wide range of topics. Attending at least three hours of educational programming (not a volunteer shift) is encouraged. Find listing of the events in the Chapter’s newsletters. Please note: these events are FREE of charge and open to the public. Bring your friends and family!
