What time do the classes meet? Each class will start at 8:30 a.m. and end at 3:00 p.m.

Is financial assistance available? Yes! Partial scholarships are available. Please email or call us for information.

Do I have to attend the entire course? Yes. Participants agree to sign up for and attend all six sessions.

What about lunch? Both morning coffee and lunch will be provided for the 5 sessions at the hotel. Plans will be announced for the September 29th field day.

Do I have to be my town’s “official” tree warden to attend?  No. We know there are many of you out there who are performing the work of a tree warden but do not have the official title. And even if you do have the title, but some or all of the actual duties are delegated to others, that’s okay too.  If you are a municipal employee and this course will be helpful to you, we welcome you!

Can I attend if I am not a municipal employee? Maybe. If you are not currently working for a town or city, we will place you on a waitlist and notify you if space is available after August 15th.

Will there be continuing education credits? Yes. CEUs will be available for certified arborists (ISA and MCA), and there will be CTSP and pesticide credits for applicable sessions.

Will this course be offered another time? The full six-session course takes place biennially, alternating years with UMass Green School. This means that the next Qualified Tree Warden Course will be held in the fall of 2023.
