Some 2026 classes will be held online and some in person at Brookhaven College. We will have small-group, in-person experiences – nature walks, field trips, meet-ups to see Master Naturalist Projects and places to volunteer, and also for you to meet and get to know fellow Master Naturalists.
Learn. Volunteer. Repeat.
How do I become a certified Master Naturalist?
- Submit the application for the class and pass the mandatory background check to be accepted into the program. To become a Master Naturalist, you must be at least 18 years of age.
- Complete the training program: 40 classroom hours (in person and online), 3 field trips (1 each for Aquatic, Prairie, and Forest ecosystems), homework, and class project.
- Obtain a minimum of 8 hours of approved advanced training and complete a minimum of 40 hours of chapter-approved volunteer service within the same calendar year.
Master Naturalists maintain certification by completing 8 hours of advanced training and 40 hours of volunteer service each year.
The next class will start on Tuesday, January 27, 2026 and run through April 28, 2026.
Preference will be given to applicants who express a commitment to stewardship of our natural resources, a willingness and availability to contribute time to volunteer service, a desire to complete the coursework, homework, and field trips, and those already volunteering.
This is a selective process and applicants will be notified of acceptance status by end of November following the application period each year.

WETLANDS Field Trip
*Note: JBS is the best place in town for wetlands education. There will be two trips to JBS on the calendar, and we are hoping that we can get 100% of trainees registered in one of these Saturday morning classes. Understanding that Saturday mornings may not work for everyone, I’ll work with those of you who can’t attend the JBS trips to try and schedule an alternative option.
