Tree Wardens' association of CT

TWAC hosts a variety of educational and professional programs throughout the year. Please read through below for more information on Tree Warden School, Workshops, and Continuing Education. 




Each fall, the Tree Wardens' Association of Connecticut conducts the Tree Warden School.  This seven week course located in New Haven is held on Thursday mornings from 8:30-12:00 (dates and location subject to change from year to year). Attendance is required at 6 of the 7 classes and a passing grade of 70% on the final exam. Tree Wardens and Deputy Tree Wardens are given top priority on open spaces for the next session, but anyone is welcome to apply to Tree Warden School. The schedule is updated in the spring. Any questions regarding Tree Warden School should be directed to the office.

The TWAC holds two educational workshops per year; once in the spring and once in the fall. The locations of these workshops are rotated around the state. Continuing Education Credits for Tree Wardens and other professions are always offered. Be sure to check out the Events page for upcoming workshops. Events are open to members and the public.

Webinars and Lunch and Learn Series are offered a few times per year during the lunch hour. The locations will rotate throughout the state, providing for regional networking and easy access, as well as virtual.  These free or low-cost workshops are complementary and supplementary to the larger workshops offered in spring and fall. The Meet n' Greet events are arranged by county and intended for regional networking.
